Ensure of the health of the wood by removing mildew stains.

No matter where mildew exists, it can be a very destructive force. It can ruin furniture, molding, or hardwood floors. Wooden surfaces will deteriorate over time, if a mildew problem is not properly dealt with. However, if mildew is caught in its early stages, it is typically easy to treat and eliminate entirely.


Step 1

Cleanse the area with a combination of soap and water. Pour some detergent into a bucket of water. Swish water so that a foam forms. If no foam forms, pour more detergent into the bucket.There is no need for any specialized soap or cleaning products. Once washed, the area should be allowed to thoroughly dry.

Step 2

Mix bleach and water together in a spray bottle. Only a capful of bleach is needed. The affected area should be sprayed thoroughly and allowed to air-dry. The surface should then be washed once again with soap and water. This will kill all traces of the mildew formation. Repeat this treatment if there is still mildew growth.


Step 3

If dealing with stubborn mildew problems, gently scrub the surface with steel wool. With this method, you must be careful not to damage the surface of the wood itself by scrubbing too hard.

Step 4

Use sandpaper as a tool to remove stubborn mildew that is embedded into the wood. Only use fine milled sandpaper in order to prevent damage to the wood. Carefully apply light pressure to remove the surface mildew. It will be necessary to paint or stain the wood afterward so that the treated area will match the color of the original wood once again.


You can increase the bleach in the cleaning solution to a quarter cup if dealing with heavily soiled areas.
