In order to clean your mobile home, you will need to either purchase or rent a pressure washer. Pressure washers have a learning curve and can be dangerous to operate. If you are not comfortable, I recommend hiring a professional power washing service. If you are ready to DIY, continue reading!

Gather the necessary tools and materials

Before you start cleaning the exterior walls of your mobile home, it’s important to gather all the necessary tools and materials. Having everything ready will help make the process more efficient and ensure a pristine finish. Here are some essential items you will need:

  1. Pressure washer: A pressure washer will be your main tool for cleaning the walls. It will provide the necessary power to remove dirt, grime, and old paint.
  2. Extension wand: An extension wand is useful for reaching higher areas of the walls. It will allow you to clean the entire exterior without straining or using a ladder.
  3. Mild detergent or cleaning solution: A mild detergent or specialized cleaning solution designed for exterior surfaces will help break down dirt and stains. Be sure that your pressure washer has a detergent loader if you are going to use this option.
  4. Soft-bristle brush: A soft-bristle brush will be handy for scrubbing stubborn areas and removing any remaining debris.
  5. Bucket: You’ll need a bucket to mix the cleaning solution and water. A 5 gallon paint bucket from Home Depot work great.
  6. Protective gear: Don’t forget to wear protective gear like gloves, safety goggles, and a face mask to shield yourself from any potential hazards.
  7. Drop cloths or plastic sheeting: To protect surrounding areas from overspray or splatters, you’ll want to cover windows, plants, and anything else that could be affected.
  8. Ladder: If necessary, have a ladder ready for hard-to-reach spots that cannot be cleaned with an extension wand.
  9. Scrapers: Depending on the condition of the walls, you may need scrapers to remove loose or peeling paint. You will need some touch up paint for these areas.

Choose the Appropriate Cleaning Solution

Before you begin cleaning the exterior walls of your mobile home, it is crucial to select the right cleaning solution. The type of cleaning solution you choose will depend on the material of your mobile home’s exterior walls.

If your mobile home has vinyl siding, a mild detergent mixed with water is usually sufficient to remove dirt, grime, and stains. Be sure to avoid abrasive cleaners or solvents that can damage the vinyl surface.

For mobile homes with aluminum siding, you can use a mixture of water and trisodium phosphate (TSP) to effectively clean the walls. TSP is a powerful cleaner that helps remove grease, mildew, and other tough stains. However, it is important to follow the manufacturer’s instructions and wear protective gloves when using TSP.

In the case of mobile homes with wood or composite siding, a gentle cleaner like oxygen bleach can be used. Oxygen bleach is environmentally friendly and can effectively remove mold, mildew, and dirt without causing any damage to the surface.

Regardless of the cleaning solution you choose, always test it on a small, inconspicuous area of your mobile home’s exterior walls first to ensure it does not cause any discoloration or damage. Additionally, follow the instructions provided by the manufacturer of the cleaning solution for the best results.

Precautions if you are painting

The main concern if you will be painting after your pressure washing, is to make sure that all surfaces are completely dry.

Any moisture must be avoided to prevent paint from peeling and bubbling.

After scrubbing the exterior walls of your mobile home, it is crucial to thoroughly rinse off any remaining soap or cleaning solution. This step will help ensure that no residue is left behind, which could interfere with the adhesion of the paint.

If you need to speed up the drying process, you can use a clean, dry cloth or towel to gently wipe away any excess moisture. However, be cautious not to leave behind any lint or fibers on the walls.

By properly rinsing and drying the walls before painting, you will create a clean canvas for your new paint job. This will help the paint adhere better and ensure a long-lasting, pristine finish for your mobile home’s exterior.
