This is not really a waterproofing wash. It is actually a gentle washing agent meant for high performance outdoor clothing to help restore and sustain the original waterproof/breathability aspects. In that it does a good job. A little goes a long way, too. If you need to restore/improve water re... Read More

  • “I would like to know if i can use this to waterproof cotton.i know nikwax has a special cotton proof on the market as well but i never see it for sale at sierra trading post so i was wondering if the tach wash will work too .”
    Asked by Mina from 10538 on 10/26/2014 7:33:49 PM
    • it didn't work very well on water proof pants that were originally waterproof and lost some of their efficiency over the years, so i highly doubt it would work on regular cotton. sorry:( it only "revitalizes" but not if the fabric is long gone:)
      thanks for asking

  • “Hello, I used Tech Wash to clean two shells. I didn't dry the shells; instead, I used the correct amount (3 oz/garment) and used a front loading washing machine and gently washed the 2 items. Then I transferred both shells to a front loading dryer and set the dryer on DELICATE and low temperature. The dryer was set for 25 minutes but stopped after only about 6-7 minutes. Both shells were still wet so I hung them on hangers overnight. In the morning they were both dry so I wore the Marmot Goretex shell in a snowstorm and later discovered that it was NOT even slightly water repellent; rather, it was soaking wet after working in the snowstorm for about one hour. Any suggestion will be very appreciated.”

    • That is really disappointing! I have not used my jacket in harsh weather so I cannot really say anything about it, yet. I will say that I followed the directions on the container.

    • There's a lot to consider, age of jacket, detergent used to wash with etc. Generally there are multiple layers that make your jacket waterproof. The first is the outer layer that is designed to repel water by acting somewhat like peach fuzz, when you first put a peach in or under running water you'll notice that the water just runs off, the same thing is what's happening with your jacket. What happens with time is that the fuzzy part of that layer gets dirty and gummed up with stuff that instead of allowing the water to run off absorbs the water and holds it. After you wash the jacket ideally it clears the fuzz of all that dirt but sometimes the detergent takes its place and that is what Tech Wash is meant for, to clear out the detergents. Depending on your jacket the fuzz could be cleared out but still matted down instead of standing up repelling water. So, depending on your jacket you may be able to steam iron it, yes, steam iron it. Your jacket may show this on the inside label or on the care instructions on the manufacturer's website. What the steam iron does is perk the fuzz back up to a standing position and making it repel water again. !!! IF YOU IRON YOUR JACKET KEEP THE IRON MOVING AND DO NOT ALLOW IT TO SIT IN ONE PLACE!!! Failing to keep the iron moving will result in a melted jacket! Now, if you're still not satisfied with with the results you can watch with TX Direct, this is purely a waterproofing treatment and I highly recommend it. Good luck!
