One of the things that can damage wood siding is mildew. If you notice mildew on your wood siding, don’t panic. With a little elbow grease, you can get rid of it. Here are a few surefire steps to removing mildew from wood siding.


  1. Cover Plants: Before you get started, you’ll want to cover any plants that are near your wood siding. This will protect them from the cleaning solution that you’ll be using. You can use old sheets, drop cloths, or towels.
  2. Protective Gear: You’ll also want to put on some protective gear. This includes gloves, goggles, and a mask. This is to protect you from the cleaning solution as well as any mold spores that might become airborne when you’re scrubbing the mildew off of the wood siding.
  3. Mix Cleaning Solution: The next step is to mix up a cleaning solution. You can use a bleach and water solution or a vinegar and water solution. Whichever one you choose, make sure that the ratio is accurate.
  4. Rinse Your Home: Once you’ve mixed up your cleaning solution, you’ll want to rinse your home with clean water. This will help remove any dirt or debris that might be on your wood siding before you start scrubbing the mildew off.
  5. Apply Cleaning Solution: Now it’s time to apply the cleaning solution to the affected areas of your wood siding. You can do this with a garden hose or a pressure washer. If you’re using a garden hose, make sure that the nozzle is set to “spray”. If you’re using a pressure washer, start with the lowest setting and work your way up if needed. Be sure to avoid any windows or doors while you’re applying the cleaning solution.
  6. Scrub Difficult Mildew Deposits: Once you’ve applied the cleaning solution, let it sit for about 15 minutes so that it can start working on breaking down the mildew deposits. After 15 minutes have passed, start scrubbing the affected areas with a brush or sponge. For really tough deposits, you may need to use a wire brush.
  7. Final Rinse: Once you’ve scrubbed all of the affected areas, it’s time for a final rinse with clean water. This will help remove any leftover cleaning solution as well as any mold spores that might have become airborne during the scrubbing process. Be sure to rinse thoroughly so that no residue is left behind on your wood siding.
  8. Let It Dry Completely: The last step is to let your wood siding dry completely in the sun before applying any type of sealer or paint.
