Steps For How To Pressure Wash Mildew And Mold

Mold and mildew are common challenges experienced by homeowners. Unfortunately, when mold and mildew occur in your home, it leads to many health challenges. For this reason, an immediate resolution is required. The best way to get rid of this nuisance is pressure washing. This post discusses how to pressure wash mildew and mold.

A guide to pressure wash mildew and mold

Getting rid of mold and mildew with a pressure washer is not as hard or challenging. Below is a guide for pressure washing mildew and mold;

Step 1: Preparations

Like any other pressure washing task, the process starts with preparation. Before you pressure wash mildew and mold, the first thing you should do is to wet the affected area. You need a solution made of water and detergent or specific chemicals for this task. An all-purpose cleaning solution may also do the trick. The chemicals from the solution will work on the mold and mildew, making it easier to remove and preventing the issue from reoccurring too soon.

Step 2: Assemble and get the pressure washer ready

Once you have prepared the area for pressure washing, the next step is assembling the machine. Remember that you need specific attachments and accessories to pressure wash mold and mildew. For instance, you need a low-pressure nozzle that can handle the chemicals used for the process. You also need a nozzle that can handle hot water applications.

Other attachments and accessories you will need to pressure wash mildew and mold are;

  • An extension wand- to help you reach high areas in your home where the mold and mildew is present
  • Detergent tank- this is necessary for a pressure washer that does not naturally come with one.

After attaching the accessories to your machine, you also need to add the cleaning solution. Again, it would be wise to prepare it separately before adding it to the machine.

Step 3: Spray the affected area from the bottom upwards

You can start the cleaning process by spraying the cleaning solution on the affected area. Experts recommend doing this from the bottom and working towards the top. At the same time, you would benefit from moving the hose horizontally with back and forth strokes. This will prevent streaking. You can work in small sections at a time for better results.

Step 4: Let the solution sit

After spraying the affected area, the next step is to let it sit for a while (5-10 minutes). This will allow it to work on the mold and mildew and loosen it. However, do not let it dry.

Step 5: Rinse

Finally, you can rinse off the area with clean hot water. Using a nozzle with more water pressure would be wise for better results. The water will pressure wash mildew and mold, leaving the area clean and attractive. Do this from top to bottom with horizontal strokes.


The trick to pressure wash mildew and mold is using the right solution or cleaning detergent. This will help you clear the mold and mildew and prevent it from reoccurring immediately after the wash.
