Cleaning concrete stains, even embedded dirt and mildew stains, is not an impossible task. There is a lot of choice when it comes to concrete cleaners, so let’s look at some of the available options.

Best Concrete Cleaners—Buying Guide

There are multiple types of concrete cleaners to choose from, so it’s important to consider what you need. The right cleaner will depend on the type of concrete, the location, and the ingredients.

Sealed or Unsealed?

This is the first factor to determine. Some cleaners only work with sealed concrete, while others work with both sealed and unsealed concrete surfaces. Sealed concrete tends to be more resistant to stains, so it’s likely to need less work when cleaning.

What type of cleaner?

As mentioned, there are lots of choices when it comes to choosing the type of cleaner for concrete. Liquid concrete cleaners are the most common, but powdered cleaners are also available. Types of liquid cleaners include:

Acidic cleaner: Usually made of hydrochloric or phosphoric acid, this type of cleaner is pretty standard for cleaning concrete. It works well to remove stains, but it can easily damage surfaces, plant life, or even the user.

Alkaline cleaner: These concrete cleaners work by removing grease and are primarily classed as degreasers, lifting hydrocarbon-based stains. The high alkaline levels emulsify the grease or oil in the stain. It typically needs to be diluted.

pH neutral cleaner: A more mild cleaning option, pH neutral cleaners are best for sealed indoor concrete. They’re safe options for areas where there are pets, vegetation, or other things that could be harmed.

Bacterial cleaner: Also known as enzyme cleaners, bacterial cleaners use active enzymes to blitz stains, break them down, and in some cases even digest them. It takes time to work, but it requires almost no work. Just set it and forget it.


While cleaning, you might also be tempted to etch your concrete floors. This is the process of applying an acid and water mixture to your floor both for deep cleaning purposes and to strengthen the bond between paint or sealant and the concrete surface. Some concrete cleaners also work as an etching product.

FullHD_best-overall-concrete-cleaner-min.jpg - 41 minutes ago

Zep concrete cleaner has several great products, and the ZEP Purple Pressure Wash outdoor cleaner is no exception. This alkaline cleaner is low foaming and easy to rinse from the concrete surface. The container makes over 12 gallons of pressure wash cleaner, leaving the surface with a clean scent. The deep cleaning formula works best on unfinished concrete and can handle even deep set-in stains.

“Great pressure wash cleanser,” wrote one reviewer. “I have been using it to pressure wash the concrete around the pool area where it can get pretty dirty and green algae. Takes it all up nicely and makes it look like fresh new concrete. Doesn't foam up to where it's a mess. Works wonders. Also used it to clean the metal siding on my garage, cleaned it up nicely as well.”

Good for: Dirt, grease

2. Best Alkaline Concrete Cleaner—Sunnyside TSP

FullHD_best-alkaline-concrete-cleaner-min.jpg - 24 minutes ago

TSP stands for trisodium phosphate, and it’s a heavy-duty cleaner that’s sure to lift stains and dirt from concrete. Sunnyside TSP is an affordable and effective solution to messy concrete, particularly indoors as the phosphate can be bad if it reaches outdoor water sources. It’s important to use safety equipment, such as gloves and a ventilation mask when working with this cleaner, as it can be harmful.

"Bought this because used cooking oil had leaked on our Legion's back patio,” one customer explained. “The oil was dark and got baked on in the hot sun and would not budge with soap and a pressure washer. I applied (during a light drizzle) and a light scrubbing. The next day it rained hard and literally washed the grease right away.”

For those who want to prepare their concrete for staining or sealing while cleaning, Krud Klutter Concrete Clean and Etch gets both jobs done. A safer alternative to muriatic acid, this cleaner uses a phosphoric acid base for etching concrete surfaces. Thanks to a special additive known as “oil grabber,” it also works hard to dissolve mildew, dirt, and stuck-on stains from grease and oil.

“I had an old furnace removed from my basement,” explained one reviewer, “that apparently leaked oil for the last 40 years into the cement. I poured this stuff straight onto the area and scrubbed with a brush. It bubbled and fizzed and went crazy for a while, then I slowly mopped it up with a huge sponge into a bucket. It really really works!”

Then, I took a scrub brush and scrubbed the Oil Eater into each stain. Waited 10 minutes and then rinsed it off with a hose. When the concrete dried, [there were] no more stains.”

“I work for a renovation company,” wrote one reviewer, “and we had a bin on the driveway that was sitting on plywood. After heavy rain for a few days, the bin leaked a lot of rusty water onto the concrete. It was very expensive compared to the other products but after applying it to the stain and watching it vanish before our eyes, it was well worth the cost.”
