Friends my workshop is in the basement. I had used my stones and put them away wet to dry. The lights were off down there and it’s pretty cool. Anyways long story short. I came back 3 days later and two had mold on the surface. How would I remove this without damaging the stone and without it being hazardous to human health?
Thank you. I now bring them upstairs to dry. Not a huge water stone guy as you may have noticed by now.
