I have a 10k mm waterproof jacket from Quiksilver and I was wondering if there is any supposed way I should wash it properly.
I know about Nikwax tech wash and have a bottle of it, but how much should I use of it?
Do I need to prepare or clean the washing machine before (from other detergents and residue) and what setting should I put it on?
Do i need to use 1k spin centrifuge? What sensitivity should I pick, a more harsh like cotton or something more easier like wool? Should I dry hang?
