How to Use Murphy Oil Soap on Vinyl Siding

Using Murphy Oil Soap on vinyl siding involves simple steps that ensure effective cleaning without causing damage.

Preparing the Solution

Mix approximately 1/4 cup of Murphy Oil Soap per gallon of water. This dilution is strong enough to tackle dirt but mild enough to preserve the integrity of the vinyl siding.

Cleaning Process
  • Wet the Siding: Before applying the solution, rinse the siding with water to remove loose dirt.
  • Apply Murphy Oil Soap: Use a soft-bristled brush or sponge to apply the solution to the siding. Work in sections to prevent the soap from drying on the surface.
  • Scrub Gently: Gently scrub the siding to remove the buildup of grime and stains.
  • Rinse Thoroughly: After scrubbing, thoroughly rinse the siding with clean water to remove any soap residue, which could attract more dirt if left behind.

Potential Concerns with Using Murphy Oil Soap

While Murphy Oil Soap can be effective, there are a few considerations to keep in mind.

Residue and Streaking

If not rinsed off thoroughly, Murphy Oil Soap can leave a residue that makes your siding streak. This, of course, is heightened if you have dark vinyl siding colors.

Compatibility with Your Specific Vinyl Siding

It would be in your best interest to contact your manufacturer for any potential warranties; in most cases, though, using Murphy Oil Soap doesn’t negate or harm the siding. It can also be achieved through a spot test to determine the product’s response.


The Murphy Oil soap is one of the best products to clean off their vinyl siding in that it has a mild formulation with the power to remove dirt and sediment from your siding. It is essential, however, that appropriate application and rinsing are well done to avoid any related issues that may arise, such as streaking or leaving behind a residue. Murphy Oil Soap is just about the best product you can find to safely and effectively clean your vinyl siding.
