Use 1 part bleach to 3 parts water, according to Sherwin-Williams. If you don't want to use bleach but do want something other than water, try vinegar, borax or branded products that you can find in a hardware store or home center, which also get rid of mold.

However, even if you sterilize the surface, there will always be enough mold spores floating in the air for mold to grow again if the conditions are right.

Whether the mold is on porous or non-porous surfaces, probably the most important aspect of cleaning is to prevent mold from reappearing.
