Mix your cleaning solution using a 1/2 cup of bleach for every quart of water. Put on a pair of rubber gloves and some form of eye protection, and cover either your clothes or wear clothing that you aren't worried about ruining.

Vacuum up any signs of mold from the floor using a wet-vac cleaner. Use the same water-bleach solution to clean out the reservoir in the vacuum cleaner if it belongs to you. Use fans and dehumidifiers to dry the area out for at least three days, and check for more mold growth. Repeat Steps 1 and 2 if the mold has returned or spread.
