Too whom it may concern; I bought the “MOLD BOMB” product a few days ago to kill 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 1 can 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. keep in mind I opened doors to old dressers to treat them as well. “IT WORKED” The basement smells new/clean. all I had to do after was to vacuum and wipe surface areas to please “wife” (but not required) this product is worth every cent. the dressers now smell of wood not mold the carpet and fabrics are not faded 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. to prevent mold from returning make sure you keep air circulating. I will advise friends to use this product.
