Please wear a mask and long gloves to protect you from the mold spores. Please note that none of these techniques will work as fast as Bleach. If you choose to use bleach, you can use bleach without chlorine. Non-Chlorinated bleach can be found at most grocery stores and health food markets. ECOVER brand (non-chlorinated bleach) is one that we use often for bathroom and kitchen cleaning. You can find this brand at most any natural food stores.
