Cleaning and Stain Removal - Isolated Basement Mold

I have asthma. How do I best clean mold from a basement floor to ensure that spores are not thrown into the environment?

When we first moved into our house two years ago we put our freezer on a plastic mat to protect it from the existing old carpeting. We recently moved the freezer to remove the carpet and discovered mold underneath (we were wearing masks).

This is most likely an isolated growth caused from the heat of the freezer. We're not concerned about a mold 'problem' as the house is very dry. Any help is appreciated!

Sounds like you are pretty right. There may be existing moisture in the basements as most basements are damp to some degree, plus the heat of the freezer did the trick.i would vaccum the area with a hepa filtered vaccum. best thing to do is rip out existing carpet and pad, if there is pad. Clean subfloor with mixture of bleach 4 oz/per gal of hot water, rinse well. Use personal protective equipment and dispose of carpet and pad according to local regulations for hazardaous material. Instead of placing freezer on a plastic mat, try placing freezer up on small bricks so no moisture can get trapped under a mat. Carpet in a basement in most households is a no win situation. i would also suggest running dehumidifers in your basement as well, if you are not already. If in doubt contact a professional mold cleaning company.

Thanks for your thoughts. I did have the dryer vented into the house in winter to add moisture, but decided against that after a short time because of the amount of moisture. Other than that, the basement is usually very dry, thankfully!

Your bleach idea confirms my thoughts, but would you use a bee mop or a shag mop or other implement to wash the floor? We have pulled up the carpeting and pad, so it's back to the concrete. Which, despite the mold, is in better shape than the carpet was. Blech!

Thanks again for your advice. Very much appreciated. :-)

i would use a shag type mop...a cheapie and use it only on that and toss it...after concrete is dry for a few days...seal it to prevent wicking of moisture
