Hi Guys
Wayne, you have hit the nail on the head with burn tests, they are ok on pure fabriccs but if there is nylon, polyester, cotton and acrylic you will not be able to seperate them by burning.
This is where wetting out becomes, in my view much more important.
If it doesn't wet out then it will almost certainly be wet cleanable, subject to dye bleed test.
If it does wet out the you could still be able to clean it but you need to wet an inconspicuos part and dry using a hair dryer, if it dries ok then you can wet clean , if it's all matted etc then probably best to leave until more experienced.
It is always worth studying a suite before cleaning, the customer will probably have used detegents to remove marks in the past, dont be afraid to ask, have they distorted the pile, are there any water marks, has it delaminated(faux suede).
Cheers
Doug
