I have berber carpet in my living room and every couple of days i will see this white stuff just magically appear on the top of the carpet. I go to wipe it away and it seems to be nothing, like it just disappears, nothing left on the towel or on the rug like it just vanishes. It's in the same spot every time. Could something be growing under the carpet? If so, is it mold and how can I fix it?
It sounds like a powder carpet deodorizer was once used on the carpet and is now walking to the surface. These gimmick products are a real nuisance once they have been administered to the carpet. According to directions they are supposed to be vacuumed from the carpet, however, that is near impossible with out a mega ton beater bar and a super volcanic vacuum cleaner. Mold only grows in high humidity, needing a food source, such as extremely soiled carpet or upholstery, wood or paper. Berber carpet, if Olefin is a tough carpet to vacuum as the fibers run horizontal with the floor, soil, spills, etc, hide under neath the carpet strands. Place your hand on the counter top, spread your fingers, imagine a spill on top of your hand, The spill will migrate down between your fingers and position itself on the bottom of your fingers. That's how Olefin carpeting is made, tough to vacuum and tough to even professionally clean.
