Carpet at Risk
If padding beneath the carpet has become wet for any reason, or has become moist from condensation, the padding as well as the carpet on top are at risk for mold growth.
Mold and dust mites thrive in damp environments, and hot water extraction leaves carpet fibers damp. Mold spores can germinate after only 12 hours in hospitable conditions, and a colony may form in as little as a day.
Clean smart. When carpeting needs to be cleaned, use a dry cleaning
How to kill MOLDS?
Nothing natural works for mold and mildew as well as this spray. I’ve used it successfully on a moldy ceiling from a leaking roof, on a musty bureau, a musty rug and a moldy shower curtain. Tea tree oil is expensive, but a little goes a very long way. Note that the smell of tea tree oil is very strong, but it will dissipate in a few days.
2 teaspoons tea tree oil
2 cups water
Combine in a spray bottle, shake to blend, and spray on problem areas. Do not rinse. Makes about 2 cups, lasts indefinitely.
