Hi all, As the title suggests I have a large wool rug in my lounge. I used 1001 no vac carpet and upholstery foam on it at the weekend and the rug now looks awful!!! The foam came out in streaks and instead of disappearing after a few mins it just left really noticeable spray tracks. It looks like someone has peed on it to be honest. There are no warnings on the can, not even a recommendation to do a patch test first. Just says it's for all rugs, carpets and upholstery so I merrily sprayed away. Does anyone here have any tips on how to clean a wool rug myself? Preferrably without having to spend goodness knows how much money on hiring a machine???
