Quick questions before starting

First, let’s answer some quick questions before we head into our main topic:

Can you pressure wash a white vinyl fence? Yes; you can pressure wash your white vinyl fence. However, if you encounter mold and mildew, you will need more than ordinary soap and water to do the job.  

How difficult is this to do? It can be pretty easy if you’re just going to eliminate minor dust and dirt buildup, but contaminants on the fence require a particular solution to be eliminated. 

Aside from that, you should also know the correct PSI setting. If you’re unsure, always reach out to an expert to ensure everything is done correctly. 

How long does it take? Generally, it will take between two or three hours to pressure wash a 500 sq. ft. fence.

How to clean a vinyl fence with a pressure washer

Now that you’ve secured all the things you need, let’s move forward with the step-by-step instructions below:

1. Get acquainted with your machine

We emphasize the importance of reading the machine’s manual, especially if you are a beginner. 

2. Prepare your fence and area

Never skip preparing and securing the area to avoid any accidents. 

If plants and essentials are immovable, ensure they are covered in a drop cloth to avoid getting soaked in water and/or chemicals.

3. Spray the fence with water

Use your hose and thoroughly wet the fence or use your pressure washer in the lowest setting. This step helps loosen up the buildup of dirt and debris. 

When using the pressure washer, always stand a few feet away and spray your way across the fence until completion. 

After loosening up dirt, stubborn stains and spots will be more visible. You can use a white vinegar solution by mixing 1 cup of vinegar into 2 gallons of water. Soak a rag in the solution and carefully rub it on the stubborn spot. 

Then, wipe down any excess vinegar with the rag or spray it with the hose to avoid leaving residue.

4. Apply the cleaner to your fence

Ensure that the cleaner you use supports vinyl fences, although you can also apply a multi-purpose cleaner. You’re good to go as long as it’s advisable for vinyl materials.

Fill the pressure washer with the solution and work from bottom to top. Always work in sections, so the solution doesn’t dry on the surface. Let the solution sit for 3 to 5 minutes to loosen up the dirt. 

Note that we strongly suggest using greener alternative solutions to protect yourself and the environment.

5. Spray off the fence with your pressure washer 

After 3 to 5 minutes of letting the solution sit, spray it off using the green 25 degree nozzle. This nozzle is suitable for wood, fences, gutters, driveways, and more. It spritzes a wide spray, rinsing more area at once. 

Vinyl materials can withstand up to 2,000 PSI. However, test out a small portion of the fence before operating in that setting so you can adjust the intensity as needed.

Note: You should still be working in sections alternating between applying the solution, letting it sit for 3 to 5 minutes, and then rinsing it off as you cover each board over time.

6. Let it dry

Before putting back all the plants or essential things against it, let it completely dry.

Professional or not, it is crucial to practice safety when operating a pressure washer. 

Follow the safety tips below to avoid any mishaps:

Stand 2-3 feet away from the surface you’re cleaning

Stand a few feet away from the surface you’re cleaning to prevent damage.

How do I remove stains from a vinyl fence?

We recommend using a white vinegar solution; mix 1 cup of white vinegar into 2 gallons of water. Soak a rag on the solution and thoroughly rub the area. You can formulate a more robust solution depending on the extent of the stain.

Vinegar solution is an eco-friendly cleaner that kills specific contaminants such as algae, molds, and stains. After pre-washing the exterior, apply it thoroughly with a rag and rinse with a pressure washer.
