What to Consider When Choosing Concrete Cleaner?

You might be interested in learning how various types of stains are removed by the various concrete cleaners since there are so many to pick from. Discover how stains are categorized, which cleaners remove the various types of stains and other helpful hints in the paragraphs that follow to help you choose the best concrete cleaner for your project.

Cleaner Type

Be mindful that different cleaners act to remove stains in different ways and respond to the concrete surface in various ways when selecting an appropriate concrete cleaner. To chemically lift stains, cleaners can use formulas that are pH neutral, alkaline, or acidic. Since concrete is made of alkaline lime, the surface needs to be neutralized after using an acid cleaner. Chemical pollutants are digested or converted into inert substances by enzyme and bacterial-based cleaners.

  • pH-neutral cleaners are often used to clean sealed concrete surfaces indoors without embedded dirt. If the concrete only requires a light cleaning, they can also be used on unsealed concrete both inside and outside.
  • The alkaline concrete cleaner is a powerful degreaser designed to remove burned oil, tar, soot, grease, and other petroleum-based stains.
  • The acid concrete cleaner is made with hydrochloric acid or phosphoric acid that reacts with the concrete surface. It is used to get rid of scaly mineral salt buildup, efflorescence, and hard water stains.
  • Enzyme cleaners come in different formulations that attack, break down, and in some cases digest hydrocarbon, starch, or protein-based stains. These cleaners use genetically modified bacteria that feed on grease and oil.

Concentration and Form

Concrete Cleaner

Concrete cleaners are available in dry or liquid applications. For removing biological or mineral stains, liquid concrete cleaners are typically used. Generally speaking, they are chemical-based cleaners, though some might be enzyme-based. When compared to concentrates, which must be diluted with water before use, ready-to-use formulations are quick and convenient but concentrates are frequently more expensive.

Dry concrete cleaners are designed to remove hydrocarbon stains from concrete’s surface and soak up liquids. Cleaners for bacteria are applied dry. When the microbes come in contact with hydrocarbons, they become active and begin to slowly eat away at the stain’s leftovers until they are gone.

Stain Type

Living organisms like moss, algae, and mold are the culprits behind biological stains. On concrete surfaces that are constantly damp, they frequently manifest as green streaks, films, or cushiony growth over a large area. In humid environments, this issue may recur, so having a quick-acting, the long-lasting fix is beneficial. Commercial cleaners work faster, and more thoroughly, and can help prevent regrowth. Home remedies like scrubbing with bleach or white vinegar are frequently advised.

Unattractive concrete stains can also be caused by spills and leaks of hydrocarbons, which include petroleum products like motor oil, cleaners, paint, and solvents. These substances seep into the porous concrete surface, causing discoloration and, in some cases, chemical reactions that could physically deteriorate the concrete surface. Make sure to select a cleaner that is advised for use on the specific spilled substance: enzyme cleaners can neutralize many volatile compounds, reducing their detrimental effects on the environment, and absorbent cleaners can remove the spilled substance from concrete.

Working Time

There is no set amount of time for cleaning; it could take a minute or several weeks. While it is relatively simple to remove and kill biological stains like algae and mold, doing so with an enzyme or bacterial cleaner can take a while for deeply embedded hydrocarbon stains. As was previously mentioned, the product’s functionality accounts for the majority of the difference in working time.

Petroleum is broken down by bacteria more slowly than by chemical processes, such as the separation of grease from concrete by an alkaline cleaner. However, there is a cost to using a fast-acting cleaner, as opposed to bacterial treatment, which breaks down petroleum pollutants into water and carbon dioxide.


Depending on the type of spill or stain being cleaned, as well as the product itself, the environmental impact of concrete cleaning products varies. Instead of releasing toxins into the environment, care should always be taken to remove and properly dispose of them.

Pressure washing is efficient and secure for use on biological stains when combined with eco-friendly cleaners because it disperses debris from the concrete surface into the surrounding environment. When possible, it is ideal to use enzyme- or bacteria-based cleaners to remove potential environmental pollutants like oil or gas.

Concrete Cleaner

Concrete cleaners carry inherent risks for skin contact, ingestion, inhalation, and other unintentional exposure even though they are safe when stored and used correctly. Store these items in a location that is out of children’s and animals’ reach. Never place them in a container without markings. Always follow the manufacturer’s recommendations for safe use, including those regarding the use of personal protective equipment, secure storage, and emergency first aid.

Cleaning Method

Cleaning procedures also vary because there are so many different cleaning products. No matter what product you use, make sure to read and abide by all safety, application, cleanup, and disposal instructions.

  • Many of the concentrated liquid products are well suited for use as a pretreatment before pressure washing. While you can use these products without a pressure washer, thorough cleaning would require a good scrub with a stiff bristle brush, followed by a thorough rinse. A wash solution made of ½ cup of baking soda and 1 quart of water must be used to neutralize the concrete surface after using an acid-based cleaner. This is done before giving the concrete a good rinse with clean water.
  • Dry-product cleaning methods vary as well. Absorbent and enzyme cleaners typically finish the job in a few hours; afterward, they are swept up and reapplied as necessary. Bacteria-based cleaners should be used indefinitely because it may take a few weeks for the microbes to fully colonize the area.
