Understanding Vinyl Siding and Power Washing

The Basics of Vinyl Siding

Vinyl siding is liked for its durability and maintenance convenience. It best survives elements and can last for decades with the proper maintenance. This does not, however, mean that grime, mold, and mildew will never collect on it, especially in humid areas or places that do not get much sunlight.

Why Power Washing?

Power washing is an excellent solution for cleaning vinyl siding, with virtually any unwanted buildup being easily washed away without the laborious elbow grease. It works by blasting away dirt with high-pressure

Characteristics of Vinyl Siding
  • Durability: Vinyl is resistant to weathering, rot, and corrosion.
  • Maintenance: It requires less maintenance than other siding materials, like wood or brick.
  • Sensitivity to cleaning: Vinyl is sensitive to harsh chemicals, which might lead to discoloration or material degradation.

Choosing the Best Equipment and Settings

Selecting the Right Power Washer

For vinyl siding, one must use a power washer that can adjust to a lower power setting. High pressure can do some serious numbers on the siding or even drive water behind the panels, creating even more significant problems. A washer with a PSI (pounds per square inch) rating between 1300 and 1600 is ideal.

Appropriate Nozzle and Pressure Settings

The key to proper cleaning without causing damage is in the nozzle that you use. A wide-angle nozzle, with 40 degrees being typical, spreads the water out over a larger area, reducing the force on any single point of the siding. Always start at the lowest setting and adjust as needed to find the right balance between being effective for cleaning and preserving the integrity of the siding.

The Best Cleaning Solutions for Vinyl Siding

Commercial Cleaners vs. DIY Solutions

While there are many commercial cleaners designed for vinyl siding, many homeowners prefer homemade solutions for their simplicity and eco-friendliness. A popular choice is a mixture of 70% water and 30% white vinegar, which effectively removes mildew and mold without harsh chemicals.

Specialized Vinyl Siding Cleaners

For tougher stains, a specialized vinyl siding cleaner available at most hardware stores can be used. These cleaners are designed to tackle heavier soiled areas without damaging the siding. Always follow the manufacturer’s instructions for the best results.

Preparing Your Cleaning Solution

Regardless of whether you choose a homemade or store-bought cleaner, it’s important to properly dilute and mix your solution according to guidelines to ensure effective cleaning. Test the solution on a small, inconspicuous area of siding first to ensure it does not cause discoloration or damage.

How to Power Wash Vinyl Siding

Regardless of the cleaning solution chosen, the technique of power washing is crucial for effective cleaning without causing damage:

Step 1: Prepare the Area

Move away all furniture, decorations, or other obstacles from the siding area.

Cover plants, electrical fixtures, and other sensitive areas to protect them from the cleaning solution.

Step 2: Apply the Cleaning Solution

Use the low-pressure setting on the power washer to apply the bottom to the top.

Let the solution sit on the siding for a few minutes to dissolve the impact of the dirt and grime.

Step 3: Rinse Thoroughly

Rinse the siding from the top down with plain water by setting the pressure higher, ensuring all the cleaning solution residue is removed.


The best product to power-wash vinyl siding with really depends on what your home’s siding needs and what you believe to be environmentally friendly. A mild soapy water or an appropriate vinyl siding cleaner works well for routine maintenance. For more demanding jobs, you may want to consider using a vinegar solution or a very diluted amount of bleach. Remember, the proper technique in the application and rinsing of the solution is just as important as the solution itself for avoiding damage to your siding.
