Mix 3/4 cup of the bleach with one gallon of water in one of the buckets. Fill the other bucket with clean, plain water.
Put on the gloves and moisten one of the sponges with the bleach solution. Use the sponge to wipe the mildew off of the wood by scrubbing it gently. Repeat this several times until the mildew is gone. Do not let water sit on the wood for too long, as it will saturate the wood and possibly warp it.
Rinse the wood with a sponge soaked in the clean, plain water once all the mildew stains are gone. Remove all of the bleach residue; if any is left it can cause the mold to grow again.
Allow the wood to naturally dry.
Things You Will Need
- Chlorine bleach
- Two buckets
- Two sponges
- Rubber gloves
- Give the rough cut wood plenty of ventilation so moisture cannot accumulate. If moisture accumulates, even after the wood is clean, the mold can possibly grow back.
