Hey all!

I'm currently cleaning out the basement and rearranging some things after my brother in law has moved out. He spent the better part of every afternoon down here working out and (I'm assuming) sweating (figuratively) gallons. I pulled the mats up to move em around and was hit with a deep earthy smell which made me IMMEDIATELY panic. There was only one super dark spot which was immediately washed off with warm soapy water and steel wool. There are other places that don't look too bad, but I am seeing markings on the floor elsewhere that match the pattern of the interlocking mat.

I'd like to keep working out down here, but I'd also like to not cause mold problems in my own house. Can anyone think of a way to essentially insulate the mat from the cement floor without creating a different problem where the plastic bottom ALSO creates an environment for the mold to grow? It's also possible that I'm WAY blowing this out of proportion...

I'll include pics on a follow up post
