Waterproof jackets keep rain out while staying breathable, but dirt, oils, and detergent residues can reduce performance. This guide explains a safe, effective routine for cleaning and reproofing, using commonly available products in the U.S. market. Following these steps helps extend the life of the jacket and preserve its water-repellent finish.
Quick Answer
Clean the jacket with a dedicated detergent designed for waterproof fabrics, rinse thoroughly, apply a reproofing spray or wash-in treatment according to label directions, and air dry. Avoid fabric softeners and high heat, which can degrade waterproof membranes and coatings.
What You’ll Need
- Nikwax Tech Wash 1L for waterproof jackets
- Granger’s Performance Wash outerwear cleaner 1L
- Nikwax TX-Direct Spray-On Reproofing for jackets
- microfiber cleaning cloth for waterproof jackets
- delicates laundry bag for jackets outerwear
Before You Start
Check the jacket’s care label for specific instructions and water temperature recommendations. Turn the garment inside out to protect zippers and surface finishes. Close all zippers and Velcro fasteners. Use cold to warm water settings—hot water can damage certain membranes. Do not use regular laundry detergents, fabric softeners, or stain removers, as these can impair breathability and waterproofing. Plan for a dry time of several hours after washing and reproofing.
Step-By-Step: How To Clean A Waterproof Jacket
- Remove loose dirt by brushing the exterior with a soft brush or rag, then spot-clean stubborn stains with a damp microfiber cloth.
- Place the jacket in the washing machine. Add Nikwax Tech Wash 1L for waterproof jackets or Granger’s Performance Wash outerwear cleaner 1L following the detergent’s dosage instructions.
- Run a cold or warm wash cycle on a gentle setting, without pre-rinse, to avoid mechanical stress on the fabric.
- Rinse the jacket on a second cycle to ensure all cleaner residue is removed. Do not add fabric softener or conditioners.
- Remove promptly after washing and gently squeeze out excess water; avoid wringing, which can distort the fabric.
- Apply Nikwax TX-Direct Spray-On Reproofing for jackets evenly over a dry surface or wash-in according to product directions for best results, then allow to air dry as specified on the label.
- If using the spray-on reproofing, re-finish any areas that appear visibly hydrophobic after the first pass for even coverage.
- For delicate fabrics or where machine washing is preferred, use a delicates bag to protect zippers and seams during washing and a microfiber cloth to buff the surface during drying.
- After drying, check the coated area by applying a small amount of water; beading indicates good waterproofing. If water does not bead, reapply the reproofing treatment as directed and air dry again.
- Store folded in a dry, ventilated area away from direct heat to preserve the coating.
- For routine care, repeat cleaning and reproofing every several months or when water stops beading on the surface.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Water no longer beads after washing | Detergent residue or worn DWR | Re-wash with cleaner, then reproof with TX-Direct | Use dedicated cleaners; avoid regular detergents |
| Dull fabric or stiffness | Excess lint or over-drying | Gently buff with microfiber; air dry fully | Dry indoors away from heat; don’t overdry |
| Stiff seams or crackling sound | Over-aggressive wash or heat exposure | Rewash with gentle cycle; avoid high heat | Follow label instructions precisely |
| Water leaks through seams | Worn DWR or seam integrity | Repair or reproof, consider professional seam sealing if needed | Regular reproofing and gentle washing |
Common Mistakes
- Using regular laundry detergents or fabric softeners on waterproof fabrics
- Washing on hot or using high heat during drying
- Over-drying or ironing coatings that may damage membranes
- Skipping reproofing after multiple washes or heavy use
Tips For Best Results
- Test a small hidden area before full application of cleaners or reproofing products.
- Follow product directions precisely for dosage and drying times.
- Pair the cleaning with a reproofing session to restore water beading and breathability.
- Store jackets in a well-ventilated area to prevent mildew and odor buildup.
Call A Professional
Consider professional care if the jacket shows persistent leaks, delamination, or visible membrane damage. Stop using the garment if the membrane appears compromised, or if cleaning products cause color fading or texture changes. Seek expert advice when dealing with expensive outdoor gear or suspected manufacturing defects.
FAQ
Can I use regular laundry detergent on a waterproof jacket?
No. Regular detergents can strip the durable water repellency and reduce breathability.
Is it necessary to reproof after every wash?
Not every wash, but most jackets benefit from reproofing after several cleaning cycles or when water stops bead.
How long should I air dry the jacket?
Allow several hours or until completely dry in a well-ventilated area away from direct heat.
Can I machine dry waterproof coatings?
Avoid high heat; air drying is generally safer, though some spray-on treatments may tolerate brief low-heat cycles as directed.
Buying Guide
When selecting products for waterproof jackets, consider size and compatibility with your jacket’s membrane. Noise level is not applicable here, but overall ease of use matters. Energy efficiency is not a primary concern for laundry cleaners, but choose concentrated formulas to reduce waste. Look for:
- <bCleaning power compatible with synthetic fabrics and membranes
- <bReproofing efficacy for restoring DWR coatings
- <bEase of use—spray-on vs wash-in options
- <bFabric compatibility—check that cleaners and repellents are suitable for your jacket’s fabric
- <bCare label alignment—adhere to manufacturer guidelines for best results
Placement considerations include indoor air quality during drying and a space with good airflow to prevent moisture buildup. For ongoing care, pairing a dedicated waterproofing wash with a reproofing treatment yields the best performance. If choosing between spray-on and wash-in options, consider your jacket’s usage: frequent washing favors spray-on for quick refreshes, while regular maintenance could leverage wash-in formulas for deeper cleaning.
