Too whom it may concern; I bought the Biocide products a few days ago to clean mold that was forming within my basement in very old vintage wool area rugs. there were also older wood dressers located in the same room. I bought some cans to treat a room slightly larger than 7000 cf. I figured with items like pool table and other large objects within the room. I would be fine. I set the spray and left the room. “IT WORKED” The basement smells new/clean. all I had to do after was to vacuum and wipe surface areas to please “wife”. This product is worth every cent. I have 3 wool rugs Worth over $9000 and was nervous at first, but I can tell you now no matter the cost of you rugs you can feel safe to use this product. I will advise friends to use this product.
