Ice Fishing Gear Detergent Guide: Cleaning Float Suits Without Losing Buoyancy
Cleaning your ice fishing float suit requires careful detergent selection to preserve both flotation capabilities and waterproofing. Use only mild, non-biological detergents specifically designed for technical outdoor gear—avoid fabric softeners, bleach, and harsh chemicals that destroy the DWR coating and compromise foam buoyancy. Cold water machine washing on a gentle cycle protects your Boreas ice fishing bibs while maintaining their life-saving float technology and weather protection.
Key Takeaways
- Use technical gear detergent (Nikwax Tech Wash, Granger's Performance Wash) to preserve flotation foam and DWR coating
- Avoid fabric softeners, bleach, and bio-enzyme detergents that break down waterproofing and foam integrity
- Wash in cold water (30°C/86°F maximum) on gentle cycle to prevent thermal damage to flotation materials
- Air dry only—never use heat, which degrades foam buoyancy and melts waterproof membranes
- Inspect flotation panels after washing to ensure no detergent residue remains that could reduce buoyancy
The wrong detergent destroys the very features that keep you safe on the ice. A $6 bottle of discount laundry soap can compromise flotation foam, strip waterproof coatings, and void your warranty on a $300 float suit. This guide shows you exactly which detergents preserve your gear's performance and which products to avoid at all costs.

Understanding Float Suit Construction
Before selecting detergent, you need to understand what you're cleaning. Your Boreas floating ice fishing suit contains multiple critical components that each react differently to cleaning chemicals.
Modern float suits combine three distinct layers. The outer shell features a DWR (Durable Water Repellent) coating that causes water to bead and roll off rather than soaking into the fabric. Beneath that sits a waterproof membrane (typically polyurethane or similar material) that creates an absolute barrier against moisture penetration. The innermost layer contains closed-cell foam flotation panels positioned strategically to keep your head above water if you break through.
Each of these components can be damaged by the wrong cleaning products. DWR coatings are particularly vulnerable to surfactants found in standard laundry detergents. Waterproof membranes can be weakened by petroleum-based solvents and harsh enzymes. Flotation foam degrades when exposed to chlorine bleach, fabric softeners, and even some "gentle" detergents containing conditioners.
The combination of these materials in a single garment makes float suit cleaning more complex than washing a standard jacket. You cannot simply toss your ice fishing suit into the washer with your regular laundry load and expect it to maintain its protective qualities.
Why Regular Detergents Destroy Float Suits
Standard household laundry detergents contain ingredients designed for cotton, polyester blends, and everyday fabrics. These same ingredients actively harm technical outdoor gear.
Fabric softeners coat fibers with waxy or oily residues that make clothes feel softer and reduce static. On a float suit, this coating clogs the fabric's breathable pores, prevents moisture-wicking, and most critically, reduces the DWR coating's effectiveness. Water that should bead and roll off instead soaks into the fabric, adding weight and reducing thermal protection. In extreme cases, the additional weight from waterlogged fabric can partially neutralize the flotation panels' buoyancy.
Biological enzymes (bio-enzymes) break down organic stains like grass, blood, and food. They accomplish this by literally digesting protein-based materials. Unfortunately, these enzymes also attack the polymers in waterproof membranes and the DWR coating's molecular structure. After just a few washes with bio-enzyme detergent, you may notice water no longer beads on your suit's surface. The enzymes have partially dissolved the water-repellent treatment.
Optical brighteners make whites appear whiter by absorbing ultraviolet light and re-emitting it as visible blue light. These compounds bond to fabric fibers and can interfere with the chemical structure of technical coatings. More importantly for ice anglers, optical brighteners do not rinse out completely and leave residues that attract dirt and reduce the suit's ability to shed water.
Chlorine bleach is perhaps the most destructive product for float suits. Chlorine oxidizes and breaks down foam cell structures, reducing buoyancy. It also degrades waterproof membranes, creating microscopic holes that allow water penetration. Even small amounts of chlorine bleach can permanently damage a float suit's protective capabilities.
Safe Detergent Options for Ice Fishing Suits
Technical gear detergents are specifically formulated to clean outdoor equipment without damaging protective treatments. These products contain carefully selected surfactants that remove dirt and body oils while preserving DWR coatings and waterproof membranes.
Nikwax Tech Wash is the gold standard for cleaning float suits and other waterproof gear. This water-based cleaner contains no harmful enzymes, fabric softeners, or optical brighteners. It effectively removes dirt, salt residues, and body oils that accumulate during ice fishing sessions without stripping the DWR coating. Tech Wash is biodegradable and safe for both front-loading and top-loading washing machines.
Granger's Performance Wash offers similar properties with a slightly different formulation. Many professional guides prefer Granger's for heavily soiled gear because it contains mild abrasive agents that lift stubborn stains without chemical harshness. Like Nikwax, it preserves waterproofing and flotation materials while thoroughly cleaning the fabric.
Atsko Sport-Wash is another viable option, particularly for anglers on tighter budgets. It costs less than Nikwax or Granger's but still avoids the harmful ingredients found in household detergents. Sport-Wash is unscented, making it ideal for hunters who also use their float suits during late-season waterfowl hunts.
For emergency situations where technical detergents are unavailable, pure liquid castile soap (like unscented Dr. Bronner's) provides a safe alternative. Use half the amount you would use for regular laundry, as castile soap creates substantial suds. Ensure thorough rinsing to remove all soap residue from flotation panels.
Never substitute these specialized detergents with "mild" or "gentle" regular detergents. Even baby laundry detergents and "free and clear" formulations often contain fabric softeners or enzymes that damage technical gear.
Step-by-Step Washing Instructions
Proper washing technique matters as much as detergent selection. Follow this proven process to clean your ice fishing bibs while maintaining their protective features.
Before washing, empty all pockets and close all zippers, Velcro closures, and snaps. This prevents hardware from catching on the washing machine drum and protects zippers from damage. Check the suit for any tears, loose threads, or damaged seams that might worsen during washing.
Pre-treat heavily soiled areas with a small amount of technical detergent applied directly to the stain. Common problem spots include cuffs, collar areas, and the seat of bibs where you sit on buckets or sleds. Let the detergent sit for 10-15 minutes before washing to break down stubborn oils and dirt.
Set your washing machine to cold water (30°C/86°F maximum) and select the gentle or delicate cycle. Hot water damages flotation foam and can partially melt waterproof membrane adhesives. High-speed spin cycles can stress seams and compress foam, so gentle agitation is essential.
Use the recommended amount of technical detergent—usually 50-100ml depending on the product and your machine's capacity. More detergent does not mean cleaner gear. Excess detergent leaves residues that attract dirt and reduce water repellency.
Run the wash cycle completely, then add a second rinse cycle with no detergent. Flotation foam can trap soap residues that reduce buoyancy and cause the foam to break down over time. The extra rinse ensures all detergent is removed from the suit's inner layers.
For top-loading machines, ensure the float suit is fully submerged during the wash. The flotation panels may cause the suit to float on the water's surface, preventing effective cleaning. You may need to manually push the suit down initially until it becomes saturated.
Front-loading machines generally provide better results for float suits because the tumbling action more evenly distributes water and detergent throughout the garment. The horizontal drum also reduces stress on seams compared to top-loading agitators.
Critical Mistakes That Void Warranties
Understanding what NOT to do is as important as following correct procedures. These common mistakes can damage your suit and void manufacturer warranties like the Boreas lifetime warranty.
Never use heat during drying. Tumble dryers, even on low heat settings, generate temperatures that degrade foam buoyancy and melt waterproof membrane adhesives. Hanging your suit near a woodstove, heater, or in direct hot sunlight causes similar damage. The flotation foam in Coast Guard-approved float suits is specifically engineered to maintain structural integrity in cold conditions. Heat exposure changes the foam's cellular structure, reducing its ability to provide buoyancy.
Do not dry clean float suits. The perchloroethylene and other solvents used in dry cleaning dissolve waterproof coatings and damage foam materials. Dry cleaning may leave your suit looking clean, but it will no longer keep you afloat or dry.
Avoid washing float suits with other clothing, particularly items with zippers, hooks, or rough textures that can abrade the suit's outer fabric. A torn DWR-coated shell compromises waterproofing even if the inner membrane remains intact.
Never store a float suit while damp or wet. Moisture trapped in flotation panels can promote mildew growth and gradually break down the foam's chemical structure. This is separate from washing but critical for maintaining the suit's integrity between uses. For complete storage guidelines, review our ice fishing suit storage guide.
Do not spot-clean with household products like dish soap, window cleaner, or general-purpose cleaners. These products often contain ammonia, solvents, or other chemicals that damage technical fabrics. If you must spot-clean between washes, use only water or a small amount of technical detergent diluted heavily with water.
Proper Drying Techniques
Air drying is the only safe method for float suits. Hang your suit on a wide, padded hanger in a well-ventilated area away from direct heat and sunlight. A basement, garage, or covered porch provides ideal drying conditions.
Position the suit to allow air circulation around all areas. Leave zippers partially open to promote airflow through the interior. Ensure the suit is fully extended rather than crumpled or folded to prevent moisture from being trapped in fabric creases.
Drying time varies based on humidity and air temperature, typically requiring 24-48 hours for complete drying. Do not rush this process. Putting away a suit that is still damp in the flotation panels can lead to foam degradation and mildew odors that are nearly impossible to eliminate.
Periodically rotate the suit during drying to ensure even air exposure. If drying outdoors, bring the suit inside before evening dew settles or if rain threatens. Outdoor drying is acceptable in dry, breezy conditions but avoid direct sunlight that can fade colors and potentially degrade outer fabrics over time.
Reactivating DWR After Washing
Even when using correct detergents, repeated washing gradually reduces DWR coating effectiveness. After 3-5 wash cycles, you may notice water no longer beads on the suit's surface. This does not mean the waterproof membrane has failed—only that the outer water-repellent treatment needs reactivation.
Heat reactivation is the simplest method for refreshing DWR coatings. Once your suit is completely dry, place it in a tumble dryer on the lowest heat setting for 20 minutes. The gentle warmth causes the DWR molecules to realign and re-establish their water-repellent properties. This is the ONLY time heat is acceptable for float suits, and only for this specific purpose.
Alternatively, use a household iron on the lowest steam-free setting. Place a clean cotton towel over the suit's surface and iron in smooth strokes. The indirect heat protects the fabric while reactivating the DWR. Never apply the iron directly to the suit's surface or use high heat.
If heat reactivation does not restore water repellency, the DWR coating may be depleted and require reapplication. DWR spray-on treatments designed for technical outerwear can restore the coating. Follow the product instructions carefully, applying the treatment to clean, dry fabric in a well-ventilated area. Allow the recommended curing time before using the suit again.
⭐ Featured Gear: Boreas Pro Floating Ice Bibs
The Boreas bibs incorporate Float Assist Technology with strategically positioned foam panels that maintain buoyancy even after hundreds of fishing days. Unlike cheaper suits with minimal foam, these bibs provide reliable flotation that remains effective when properly maintained with correct washing techniques.
With 150+ grams of insulation and Coast Guard-approved buoyancy, these bibs keep you warm AND safe on the ice. Proper cleaning preserves both features for years of reliable service.
Water Temperature and Machine Settings
Cold water is non-negotiable for float suit washing. Water above 30°C (86°F) begins to soften foam cellular structures and can weaken adhesives used in waterproof membrane construction. Always verify your washing machine's temperature before starting the cycle.
Machine agitation should be minimal. Select "delicate," "gentle," or "hand wash" cycles if available. High-speed agitation stresses seams and can cause delamination where waterproof membranes are bonded to fabric layers.
Spin speed affects how much water remains in the suit after washing. While you want to remove excess water to speed drying, high-speed spinning (above 800 RPM) can compress flotation foam and stress seams. Choose low or medium spin settings to balance water extraction with garment protection.
Frequency: How Often to Wash Float Suits
Wash your ice fishing suit only when necessary. Unlike regular clothing that requires washing after each use, float suits should be washed 2-4 times per season for most anglers. Over-washing accelerates DWR depletion and adds unnecessary wear to waterproof membranes.
After each fishing trip, hang your suit to air dry and brush off any surface dirt, snow, or ice. This simple maintenance removes 80% of the soiling that would otherwise require washing. Spot-clean minor stains with a damp cloth and small amount of technical detergent rather than washing the entire suit.
Wash when you notice body odor that airing out does not eliminate, visible dirt or stains that affect performance, reduced water repellency across large areas of the suit, or at the end of the season before storage. End-of-season washing removes body oils and salts that can break down fabrics during summer storage.
For anglers who fish multiple days per week or guide professionally, monthly washing during the active season may be necessary. However, most recreational anglers find 3-4 washes per winter sufficient to maintain cleanliness without excessive wear.
Special Considerations for Hard Water
Hard water contains dissolved minerals (primarily calcium and magnesium) that can interfere with detergent effectiveness and leave deposits on fabric. If you live in a hard water area, these minerals can gradually accumulate in flotation foam and reduce buoyancy.
Use slightly more technical detergent in hard water to compensate for the minerals binding to surfactants. Adding a water softener to the wash cycle improves cleaning effectiveness, but ensure the softener contains no fabric conditioning agents.
After washing in hard water, run an additional rinse cycle with one cup of white vinegar added to the rinse water. The vinegar dissolves mineral deposits without harming technical fabrics. Ensure you run a final clear water rinse after the vinegar rinse to remove any acidic residue.
If possible, collect rainwater or use distilled water for washing float suits. While impractical for filling an entire washing machine, you can hand-wash a float suit in a bathtub with 10-15 gallons of soft water, achieving better results than machine washing with heavily mineralized water.
Hand Washing as an Alternative
Hand washing provides maximum control over the cleaning process and eliminates concerns about washing machine agitation damage. For high-value suits or those with complex features, hand washing is often the safest option.
Fill a bathtub or large basin with cold water (approximately 15-20 gallons). Add the recommended amount of technical detergent and agitate the water to distribute it evenly. Submerge the float suit completely, pressing it down to force water through all layers.
Gently work the fabric, paying particular attention to heavily soiled areas. Avoid harsh scrubbing that can abrade the DWR coating. Let the suit soak for 20-30 minutes, occasionally agitating it to maintain water circulation through the fabric.
Drain the soapy water and refill the tub with clean cold water. Rinse the suit thoroughly, pressing gently to flush detergent from the flotation panels. You may need 3-4 rinse cycles to completely remove all soap residue—continue rinsing until the water remains clear and produces no suds when you agitate the suit.
Gently press excess water from the suit without wringing or twisting, which can stress seams and damage waterproof membranes. Hang to air dry as described previously.
Inspecting Float Panels After Washing
After your suit is completely dry, inspect flotation panels to ensure washing did not compromise their integrity. Lay the suit flat and carefully feel each foam panel, checking for soft spots, areas where foam feels compressed or degraded, and any changes in thickness or density.
Foam panels should feel uniformly firm with slight give when pressed. They should return to their original shape immediately when pressure is released. Any areas that remain compressed or feel noticeably softer than surrounding foam may have been damaged by incorrect washing methods.
Check seams where foam panels are inserted into the suit. These areas should show no gaps, loose stitching, or separation. The fabric surrounding foam panels should be smooth and tight, not bunched or wrinkled, which could indicate the foam has shrunk or degraded.
If you notice any concerns about flotation panel integrity, discontinue use immediately and contact the manufacturer. Never assume flotation will work correctly if foam panels show signs of damage. For suits covered under warranty, damage from improper care products may not be covered, making correct detergent selection critical from the first wash.
The Complete Ice Fishing Suit Care System
Proper washing is just one component of comprehensive float suit maintenance. To maximize your investment and ensure reliable protection season after season, combine washing with proper storage, periodic waterproofing renewal, and regular inspections.
Between fishing trips, hang your Boreas ice fishing suit in a climate-controlled space away from temperature extremes. UV exposure gradually breaks down both fabrics and DWR coatings, so avoid long-term storage in direct sunlight.
Before each season, inspect all zippers, snaps, and Velcro closures. Apply zipper lubricant to main entry zippers to ensure they close completely and create a waterproof seal. Test the suit's water repellency by splashing water on various areas—if water soaks in rather than beading, reactivate or reapply DWR treatment before your first fishing trip.
All Boreas ice suits are backed by our industry-leading lifetime warranty, but this coverage requires following proper care procedures. Using correct detergents and washing methods preserves your warranty protection and ensures your suit provides reliable safety features for years of ice fishing.
"I've been washing my Boreas bibs with Nikwax for three seasons now, and they still bead water like new. The flotation foam hasn't compressed at all, and I feel completely safe on late ice when conditions get sketchy."
