How to Choose the Best Concrete Cleaners
How good your concrete driveway cleaner works on the stains on your driveway will depend entirely on finding the right product with the right features.
In this section, I’ll cover the most important information that you need to know to make the right choice to get rid of your stains and dirty patches.
Type of cleaner
Look through the cleaners we’ve listed above and look for the one that’s best suited to your stains.
Look at the pH factor which is about how acidic or how alkaline the formula is.
The two most common concrete issues, oils, and efflorescence require cleaning with either an alkaline or acidic cleaner.
There are also neutral cleaners that have a pH of 7, and these are great for mild cleaning of sealed concrete floors.
Finally, there are also novel enzymatic and bacterial cleaners; these are perfect for dealing with pet stains and other hydrocarbon and protein-based dirt, which is trapped inside of the porous concrete.
Value for money
Like with various types of pressure washer foam cannon soaps, concrete cleaners in either a diluted ready-to-use form or in a concentrated formula.
Look at the price per ounce rather than the overall price, as this is where you’ll find the true value of the product. Concentrated cleaners need to be diluted and these concrete cleaners are the most cost effective.
Sealed vs Unsealed Concrete
Before purchasing any concrete cleaners, you need to check whether you have sealed or unsealed concrete. If you have any doubts, go for a pH-neutral cleaner. It’s safe on both.
Eco-Friendliness
Many people choose to go for eco-friendly options, which is very important if there’s wildlife or plants nearby. There are a lot of biodegradable and eco-friendly concrete cleaners on the market.
Ease of use
Seems an odd thing with a concrete cleaner, but be sure to check whether it’s made for us with a pressure washer or suitable without one, check to see how much scrubbing is required. Some concrete cleaners need more effort than others.
Versatility
Many concrete cleaners will work on a variety of surfaces, both indoors and outdoor surfaces. While you might be happy with one designed for concrete surfaces. A lot of people are looking for a product that goes a step further, and can be used on multiple surfaces.
Check and see what surfaces and purposes your cleaner has.
Toxicity
It’s worth considering whether the formula is toxic or contains harsh chemicals, this is especially important with pets or kids around.
Do You Need a Concrete Cleaner?
When it comes to curb appeal, one thing that stands out is cleanliness. Your yard and the façade of your home are facing a constant battle with and grime. As time goes on, lime and mortar residues, algae, moss, and efflorescence all build-up, leaving your concrete looking dirty and dull.
Concrete is porous with anywhere between 5 and 20% of the surface being tiny holes. These little holes hold onto the dirt, oil particles, and water, this makes concrete cleaning a tough task.
Because of this your regular pressure washer soap or detergent falls short without a little help, such as using concrete cleaners and perhaps even a surface cleaner or brush.

This is one of those natural concrete cleaning products for oily stains within your concrete, you don’t need to use any protective equipment, just time and patience.
This product is entirely natural and risk-free. Its effectiveness comes from the microbes it contains, these will feed on the petroleum compounds. This concrete cleaner works on concrete, asphalt, and even porous stone.
Though it won’t help with efflorescence or animal grease.

Then let those microbes get to work; they will slowly eat away the oily stain for a few days. Every once in a while, re-mist the area with some water to keep the microbes going. There’s no need for scrubbing, just sweep the area after a couple of days and repeat the process until the stain is gone.

FAQ About Concrete Cleaners
1.What is efflorescence, is it harmful, and how to get rid of it?
Efflorescence is one of the most common issues that people face with their concrete driveways, patios, or footpaths. It’s really easy to identify, it’s the white powder on unsealed concrete or a white blush on sealed floors.
The problem with Efflorescence is that it can appear out of nowhere, what’s happened is that water has risen to surface from within the concrete slab, and as the water vapor evaporates away, the salts are left behind. These white streaks you see are caused by a sort of salt, a mineral that exists in most modern concrete.
Normally a build-up of efflorescence will simply wear away, you can even sandblast it away, but there are times when it can be rather stubborn. So if you’ve tried to wash it away with your pressure washer and it’s not helping, then your concrete may need treatment from an acidic cleaner to remove the salt deposits.
However, if you aren’t bothered by the white residue, then leave it be. It causes no harm, and efflorescence can’t hurt the structural integrity of your concrete, it’s entirely an aesthetic problem. However, it can indicate high moisture levels.
2. What do I need to know before cleaning efflorescence with muriatic acid?
If you’ve been dealing with a build-up of efflorescence for a while, then you most likely have come across muriatic acid when you’ve been doing your research. If not, then you may know it as an acid that can be used to unclog blocked drains.
This is a powerful acid traditionally used to rid concrete of the white powdery substance, but today you can use milder and much easier to handle acidic products that are just as effective.
Muriatic acid is the strongest acid that you can get commercially, but because of how strong it is, you should be very careful if you chose to use muriatic acid on your own.
Keep a spray bottle nearby, which has a mix of water and baking soda when you are working with muriatic acid. Baking soda can be used to quickly neutralize the acid, should anything go awry. Use half a cup of baking soda for every one quart of water for the best results.
Personally, I suggest using a professional instead of using muriatic yourself.
3. Can I use bleach to clean concrete?
Yeah you can. Just mix some household bleach with water to clean your concrete. This will remove mold, mildew, dirt and grime. It’s not a complete stain removal option, but it does a good job.
Combine this with a scrubber for some deep cleaning. Any embedded dirt or odors will be removed. Just never mix bleach with other chemicals, as this can lead to toxic gases.
Bare in mind that this isn’t the most eco friendly concrete cleaner.
4. Can you use Chlorine to Clean Concrete
Similar to the above about bleach, you can use chlorine bleach to clean your concrete. Again though, don’t mix this with different cleaners or other chemicals. Again, this isn’t the most echo friendly concrete cleaner.
4.Can I spray concrete cleaner with my pressure washer like soap?
No. Most concrete cleaners are very different when compared to a vinyl siding shampoo or any other pressure washer soap. These aren’t designed to bubble or foam up.
Acidic, alkaline, and enzymatic or bacterial cleaners are all different in how they achieve their results, but none of them should come into contact with your pressure washer soap tank, and they certainly shouldn’t go through your pressure washers pump as this may cause serious and permanent damage.
Instead, you should apply these chemicals by hand and then bring your pressure washer in later to rinse these chemicals away.
6. Does Dawn dish soap remove oil from concrete
Yes, believe it or not, this is a very common and safe way to remove oil stains from concrete. Just mix your dish soap with hot water and scrub the surface with a stiff bristle brush. It does a fairly good cleaning job for removing oil stains.
7. Does WD-40 Remove oil stains from concrete
While, yes WD-40 does remove grease stains. It’s not as effective as other cleaning solutions. Especially if the stain is old, we really don’t recommend you use WD-40 on these as it won’t work very well. Though you can always try.
Just spray the stain, wait 30 minutes and scrub with a brush, then sprinkle over some cat litter to absorb any excess.
8. Does Coca-Cola Remove oil stains from concrete
co*ke is acidic so yeah, it’s rather effective on oil stains. Just pour over a few cans of room temperate co*ke, let it sit for around a day and then blot with some old towels.
Wrap Up with some Clean Concrete
No one wants to see stained, marked, scuffed up and dirty concrete, even more so if you are selling your house, have guests or have just spring cleaned your home.
Fortunately concrete is rather easy to clean, even more so when you use one of the best concrete cleaners on the market.
Do keep in mind the type of concrete, when its unsealed or sealed. Again, pay attention to the ingredients and the versatility and get the best concrete cleaner for your home.
We’ve covered how concrete cleaners work, the different types of concrete cleaners and what works best for different surfaces and dirt/stains.
