cleaning marble in a shower, unfinished marble

Q. I have unfinished marble in our shoewr, I see mold in some of the natural holes in the marble.Can I use comet cleanser on it? Not sure what to use. Thank-you, Marie Merritt Island, FL

A. Marie-Sorry for the delay in answering. Do not use the comet!

Our MB-9 mold and mildew remover is a superior product for the removal of mold.

You could try some chlorox as well. Try diluting it 50/50

with water and spray it on then let it sit for five minutes or so.

Dont forget to test an area first before using any chemical product.

Protect your hands and eyes as well.
