Best Concrete Cleaners for Pressure Washers

Cleaning concrete surfaces, especially if they’re unsealed, is one heck of a task. The concrete pavements in the outdoor space of the house accumulate dust, dirt, mildew, vehicle oil spills, and tire stains all the time. When outdoor concrete surfaces are neglected for too long, all the aforementioned pollutants bake on them in the form of a greasy layer.


In a Hurry? Here are Our Top Choices

But many times while cleaning concrete structures, even the water jet of the pressure washer falls short.

What to Consider when Buying Concrete Cleaner for a Pressure Washer

First of all, make sure that the concrete cleaner you pick categorically mentions its use with a pressure washer on its label. After that, consider the following factors.


Non-toxic and Eco-Friendly Formula

Today, you can easily find heavy-duty concrete cleaners that sport non-toxic and eco-friendly formulas (e.g., all the cleaners we’ve reviewed here). Make sure that the cleaner has a biodegradable composition and doesn’t contain a high concentration of bleaches and phosphates.



When you’ve to use a concrete cleaner with a pressure washer, always pick the concentrated products. Usually, one part of a good concentrated cleaner can make 11 parts of a diluted cleaning solution. Top-of-the-line concrete cleaners also come with dilution guides and charts to help you make the right mix.



You can find both exclusive and versatile concrete cleaners on the block. The latter can get rid of dirt, grime, and grease from other material surfaces (wood, stone, asphalt, vinyl, tile, etc.) as well. Carefully read the label to find out if a cleaner is versatile or not.



Any top-quality heavy-duty concrete cleaner for pressure washer should not cost you more than $25.
