How to Choose the Best Concrete Cleaners

With all of these different types of cleaners on the market, how can you choose the best one? We think it’s important to consider some of the most crucial details. This includes what type of cleaner it is, what type of concrete it is for, the eco-friendliness, and more.

Sealed vs Unsealed Concrete

You should check if the cleaner will work on your concrete, whether you have sealed or unsealed concrete. When in doubt, go for a pH-neutral cleaner which is safe on both.

Type of Cleaner

Go through the types of cleaners from above to find the best one for the stains you’re dealing with. You have the option of pH-neutral, acidic, alkaline degreasers, enzymatic, and speciality cleaners. Recap the pros and cons so you know what to expect.

Eco-Friendliness

Many people want to opt for an eco-friendly cleaner, especially if there are plants and wildlife nearby. There are lots of biodegradable and eco-friendly formulas on the market.

Value for Money

Concrete cleaners come in a range of prices. Look at the price per ounce rather than the overall price. At the same time, you should consider if the product is concentrated or not. Concentrated cleaners need to be diluted, but they generally are more cost-effective.

Ease of Use

Consider how easy the product is to use. Be sure to check if it’s made to be used with a pressure washer. It may be suitable for use without one, but check how much scrubbing is required. Some cleaners are easier and quicker to use than others.

Versatility

Many concrete cleaners work on a range of surfaces, indoors and outdoors. While you may be happy with one specifically for concrete, many people want a product that goes a bit further. Check how many surfaces and purposes the cleaner that you’re looking at has.

Toxicity

Last but not least, consider if the formula has toxic or harsh chemicals. This is especially important if you have kids or pets around.

Concrete Cleaner FAQs

Can You Clean Concrete With Bleach?

Yes, you can mix household bleach and water to clean your concrete. This can remove mold, mildew, dirt, and grime. Combined with a scrubber, this can also release embedded dirt and odors. Just be sure never to mix bleach with other chemicals as this can lead to toxic gases.

Can You Use Chlorine to Clean Concrete?

Similar to the above, you can use chlorine bleach to clean your concrete but don’t mix with any other cleaning chemicals.

Does Dawn Dish Soap Remove Oil from Concrete?

Yes, this is a very common and safe way to remove oil stains from concrete. Just mix together dish soap and hot water and scrub the concrete surfaces. Afterwards, rinse the concrete with water.

Does WD-40 Remove Oil Stains from Concrete?

WD-40 can remove grease stains, but it may not be as effective as other cleaning solutions. If the stain is old, we don’t recommend this as it won’t work super well. You can always try it though! Just spray it onto the stain and wait 30 minutes. Scrub well with a brush. Sprinkle cat litter over the spray to absorb the excess.

Does Coca-Cola Remove Oil Stains from Concrete?

Coke is acidic so it’s pretty effective on oil stains. Just pour a few cans of room temperature coke over the stains. Let it sit for up to 24 hours and then blot up with some old towels.


Clean Concrete

Nobody wants scuffed up, stained, marked, dirty concrete, especially if you’re renovating, having guests or selling your home. Thankfully, concrete is pretty easy to clean, especially when you use one of the best concrete cleaners on the market.

Keep in mind to shop within your type of concrete, whether that’s sealed or unsealed. You should also consider the type of concrete as that will determine how well it can remove the stains at hand. Other details to consider include the ingredients, the ease of use, and the versatility.

Keeping all these factors in mind will help you find the best concrete cleaner for your home.
