Tip

If there are creases or hard-to-reach small places on your wooden surfaces, use a small scrub brush or toothbrush to clean it.

If mildew is a common problem on your exterior wooden surfaces, consider repainting with a paint designed to prevent mildew.

Warning

Never mix bleach with any other cleaning products, especially those containing ammonia, as this will create toxic fumes.

Do not allow bleach solution to come in contact with any plants for grass, as bleach will kill them.

When the exterior wood on your home is primed and painted properly, it can look beautiful, and you may think your work is done. However, like any surface exposed to the elements, painted wood on the exterior of your home easily collects dirt, grime and mildew that ruin the look of your home. If it remains long enough, it can even damage the paint or the wood itself.
