what soap do you use to wash waterproof trousers?

[brimfull]

the label says to use pure soap only or specialist cleaner(regatta isotex???) which sounds expensive.

Just sponge off.

You can buy pure soap flakes, but frankly washing waterproofs is a PITA. They drip for ages and are less waterproof afterwards. And they're only going to get muddy again, so not really worth going overboard on.

Usually it means to use a Non-bio product. Anything else will damage the fabric, and the waterproofness.
Usually no fabric conditioner either - for same reason

damn-actual physical work then.

if just mud etc sponge off

we use Nikwax Tech Wash (from Millets etc) when things get really grubby - not cheap but you don't need much and if you make up a whole load (waterproof jackets, ski stuff etc) you clean a lot of stuff for your money.

i stick them in the washer no harm has come to them

may get that nrs badger,dd has been on DofE expedition this weekend and all her waterproof stuff is disgusting and smells of swamps.
Hope I don't bugger up the waterproofing as her legs were the only dry bit of her,coat was worse than useless.

if coat needs redoing they do a wash-in waterproofer in the same range - have a nosey

thanks will do

I just machine wash DS's with no detergent at all - seems to work

I work for a kids waterproof clothing company and we suggest non bio powder and no fabric conditioner or softner! The conditioner/softner affetcs the waterproofing of the garments!!!

i use nikwax too.

You should try [[http://amzn.to/1KFxbUp
Nikwax cleaner]], it's not that expensive and it's suitable for use on all fabrics. I've been using it for a long time and it gets the job done every single time. Give it a try!
