Whole room - but I cannot use standard cleaner with the rented steam machine. Fibers of wool carpet do not stand up to regular cleaner.
My suggestion is to contact a reputable carpet cleaning company if this is a special carpet. I use Service Master for may rentals but I know they do specialty stuff like wool and burbers and the price is reasonable. I also heard a guy on Mark Levin’s radio program that had a nationwide carpet cleaning company that didn’t use chemicals. I forgot the name though.
Just a thought.
What I sell is the rug renovator with the rug
renovator foaming shampoo in my shop.
Any vacuum repair shop should have it or
can get it. Works on any type carpet, even
Oriental rugs. Hope this helps.
