Best Soap and Detergent for Pressure Washer (2021)

A Buying Guide to Pressure Washer Soap and Detergent (Reviews 2021)

Soap and detergent are two of the most commonly used cleaning agents around the world. When used in a pressure washer, they can clean almost anything – from a cake of hardened muds to fatty oil and thickened oil. Without using the right soap or pressure washer, deep cleaning could be next to impossible.

Difference Between Soap and Detergent

Before we unveil our top pick for pressure washer soap/detergent available in the market, it’s important to discuss the distinctions between these two. Although soaps and detergents are interchangeably used quite often, they are different in a few ways.

The most important distinction of the two is that soaps are made from natural ingredients while detergents come from synthetic components. This means that soaps are more eco-friendly, while detergent leaves small traces of chemicals that can harm the environment and your skin and eyes. In terms of performance, detergents are stronger than soap and used by professionals.

Knowing these facts, you have to consider some factors. If your local government prohibits the use of chemicals for cleaning, go with soap. For deep-cleaning purposes, you need the stronger performance that detergents provide. If you’re going to use soap on a pressure washer, it can also work well against tough dirt and stains.

Top Picks for Pressure Washer Soaps or Detergents

What’s the best pressure washer soap or detergent right now? The answer depends on a few factors, such as the purpose of cleaner, intended result, and the surface to be cleaned. Your budget will not be a big factor to consider since most brands are priced almost the same.

Note: Once you find the right brand, use it for good. Using different brands on the same surface can lead to discoloration and deterioration of materials.
