Remove everything from the furniture if necessary, including emptying out drawers and clearing out shelves.
Move the furniture outside to be cleaned. Set it on a tarp or on a clean area of concrete.
Inspect the furniture thoroughly for visible signs of mold or mildew. If you encounter mold, brush it away with a soft-bristle brush.
Dissolve 2 tablespoons of powdered laundry detergent into 1 quart of warm water.
Dip a sponge into the solution, and wipe down the furniture with it. Don't forget to wring out the sponge so as to not oversaturate the wood.
Rinse the furniture with a damp cloth to eliminate the soapy residue. Use clean, warm water, and wring out the cloth well.
Mix 1/2 cup of chlorine bleach with 1 gallon of water, and use it to disinfect the furniture.
Leave the furniture outside to air-dry. If it’s raining, keep the furniture in the garage or another location that is dry and cool to allow for proper ventilation. If you must keep the furniture indoors, place a fan nearby, or use a dehumidifier to help eliminate moisture from the wood.
