Review: Essential for Waterproof Gear – Works Like a Charm! - I’ve been using Nikwax TECH WASH for my waterproof jackets, hiking gear, and outdoor clothing, and it does an amazing job at cleaning while maintaining the waterproof properties. Unlike regular detergents, which can break down waterproof coatings, this gently cleans while reviving the fabric’s breathability and water repellency. It’s easy to use—just add it to the washing machine like a normal detergent or hand wash for smaller items. I’ve noticed that after washing, water beads up on my gear again, showing that it really does help restore the waterproof layer. It also removes dirt and odors effectively without damaging the fabric. Pros: Restores and maintains waterproofing Gently cleans technical and outdoor gear Easy to use in a washing machine or by hand Doesn’t leave residue or reduce breathability Works great on Gore-Tex and other waterproof materials Cons: Not a traditional waterproofer, so for full restoration, you may need to follow up with a Nikwax waterproofing treatment Slightly pricey, but worth it to extend the life of expensive gear Overall, Nikwax TECH WASH is a must-have for anyone who owns waterproof clothing or outdoor gear. It keeps jackets, trousers, and other equipment clean while preserving their water resistance. Highly recommended!

## Questions & Answers

**Q: Can I machine wash my jacket?**
A: Most waterproof breathable jackets are machine washable but always read the care label first. Nikwax supports the use of machine washing with its wash in products to provide fast, effective and even application.

**Q: How often do I need to treat a garment or item of gear with Nikwax Proofing Products?**
A: For light use, reproof once a year and for heavier use, reproof 2-3 times a year. If your item is wetting out, you may need to reproof more frequently.

**Q: What are the advantages to using Nikwax TX.Direct Wash-In instead of TX.Direct Spray-On?**
A: Using TX.Direct Wash-in means the clothing will be evenly coated and the proofer will reach hard to get to places. Using Spray-on can be useful as you can target specific areas of the jacket that need waterproofing anytime, anywhere.
