Nikwax TECH WASH and TX DIRECT Twin Pack, Technical Cleaner and Wash-In Waterproofer for Waterproof Clothing, 2x 300ml
About this deal
Direct are both really easy to use: measure out, send your clothes through the washing machine a couple of times et voila! It's effective at stopping both waterproof garments like Gore-Tex shell jackets and softshell products like Castelli Nanoflex from wetting out and so keeps them working well, although the treatment doesn't seem to last as long as the box-fresh water repellency - which is generally true of cleaners and reproofers and isn't unique to Grangers products.
I’ve not used the Spray-In quite as much as I thought I would, preferring just to get a whole jacket clean and waterproof and the convenience of the washing machine. Dosing, and therefore the cost per treatment, varies on the hardness of your water and how many re-washes you need per reproofing. We tested this on an old, well-loved jacket, which would previously get saturated immediately in the rain.
All you have to do is fill two caps full of the liquid, pop it in the washing machine with the garment and hit start on a full cycle as you would with regular detergent. Direct Wash-In in your washing machine for re-proofing to give really comprehensive cover in all the nooks and crannies. The Tech Wash is really easy to use, you just add it as a normal detergent in your washing machine (or hand wash if you’re that way inclined).
Standard laundry detergents won’t cut it because they leave residues on your jacket, causing the DWR layer to wet out.
If you have garments with wicking linings or want to reapply to hardwearing areas (or items such as tents) then the TX. Once the garment has been washed, you’ll need to tumble dry it or (lightly) iron it to activate the waterproofing. Instead the waterproofing solution actually revitalised the jacket and trousers to the extent that the mud, splashes and rain just beaded on the surface of the clothes and ran off.
