Do You Need a Concrete Cleaner?
A concrete cleaner is needed for removing lime and mortar residues, moss, and algae off concrete and natural stone surfaces, stucco walls, and facades. Concrete is porous, which is why regular pressure washers and soap or detergents can make little holes in it or deepen the existing ones by 5 to 20%. All-purpose detergents and floor cleaners aren’t strong enough to remove layers of dirt or moss off the concrete, unlike specialized concrete cleaners that efficiently remove salt residue, road grime, and oil stains.
Concrete Cleaner Buying Guide
The pH factor and the type of formula, concentrated or diluted, are factors that should be considered when buying concrete cleaners.
1. The pH Factor
The pH factor measures the acidity or alkalinity of concrete cleaners. Stained and oily concrete surfaces require cleaning with acidic or alkaline concrete cleaners. Neutral concrete cleaners that have a pH value around 7 are most suitable for mild cleaning of sealed concrete floors. Enzymatic and bacterial concrete cleaners are most suitable for cleaning pet stains and other protein and hydrocarbon-based dirt trapped inside the porous concrete.
1.1. pH Neutral Cleaners
Interior concrete surfaces such are sealed with a top-coat that keeps dirt from creeping into cracks and holes. pH neutral concrete cleaners work best on top-coated interior surfaces since they can efficiently remove contaminants without damaging the concrete. pH neutral concrete cleaners can be used on unsealed concrete surfaces, especially when used with pressure washer surface cleaners.
1.2. Acidic cleaners
Efflorescence is a type of dirt that is native to concrete and it is caused by water vapor rising through the slab of concrete that is bringing salt to the surface. The best way to remove efflorescence and crystalline salt off concrete surfaces is to use acidic concrete cleaners. After applying an acidic concrete cleaner, the surface should be neutralized and rinsed with an alkaline formula such as baking soda and water several times.
1.2.1. Acid type
Diluted muriatic acid, sulfamic acid, and phosphoric acid are the three most types of acidic concrete cleaners. Diluted muriatic acid is highly efficient yet hazardous to use, which is why all precautions should be followed when applying it. Sulfamic acid is less dangerous and equally effective such as diluted muriatic acid. Phosphoric acid creates fewer fumes and it is used for cleaning interior concrete surfaces.
1.3. Alkaline cleaners
Alkaline concrete cleaners, also known as concrete degreasers, are most effective with years-old grease or oily stains. Alkaline concrete cleaners break down oily substances gradually, which is why they should be left to sit for about one hour on the surface, after which the stains should be easy to wash away. Concrete is naturally alkaline, so alkaline concrete cleaners are often used for neutralizing concrete surfaces after they have been cleaned with acid cleaners.
Alkaline surface cleaners can be harmful to paints and damage aluminum and shouldn’t be used for cleaning indoor concrete surfaces because they create vapors.
1.4. Enzymatic and Bacterial Cleaners
Enzymatic and bacterial concrete cleaners are a natural, risk-free solution for cleaning grease and animal urine stains.
Enzymes are natural catalysts that are used to speed up chemical processes. There are 7 types of enzymes, some of which include lyases that are commonly used on oily stains, proteases that work best on protein stains such as pet urine, and amylases that remove carbohydrate or starch-based stains.
Enzymatic and bacterial concrete cleaners can break down different types of oils and are highly effective with removing petroleum compounds whilst not being harmful to other materials, plants, pets, or humans. Bacterial concrete cleaners don’t have to be rinsed since they dissipate on their own, yet require scrubbing the surface using a brush.
2. Diluted or Concentrated Formula
Similar to foam cannon soaps, concrete cleaners can be diluted or concentrated. pH neutral concrete cleaners are concentrated and packed in the quarter, half-gallon, and gallon bottles. pH neutral concrete cleaners pose no danger to objects, plants, pets or humans and can be diluted in different ratios, depending on the formula.
Acidic and alkaline concrete cleaners are mostly pre-diluted while concentrated products should be used according to the type, severity, and age of the stain. When dealing with less severely soiled concrete stains, acidic and alkaline concrete cleaners can be mixed with clean water.
FAQ About Concrete Cleaners
1. What is efflorescence, is it harmful, and how to get rid of it?
Efflorescence is the white powder that appears on unsealed concrete surfaces or white blush on sealed concrete floors. Efflorescence rises to the surface from inside the concrete slab, when white streaks caused by salt start appearing on the concrete surface.
Efflorescence is not harmful to the structural integrity of concrete, yet it may take some time to be washed off, which is when acidic concrete cleaners should be applied to remove the salt deposits. Efflorescence can be sandblasted away while using concrete cleaners is the most effective solution for removing it.
2. What do I need to know before cleaning efflorescence with muriatic acid?
Muriatic or hydrochloric acid is hydrogen gas in water that should be diluted with water in acid-resistant plastic containers. Water shouldn’t be poured over muriatic acid but vice versa, otherwise, the acid may explode and cause injuries. Muriatic acid is the strongest commercially available acid for removing efflorescence from concrete that should be applied using a spray bottle.
Complete body protection, including gloves, goggles, and a breathing mask should be worn when applying muriatic acid on concrete surfaces since it releases strong fumes. After applying muriatic acid on concrete, the surface should be neutralized with baking soda.
3. Can I use bleach to clean concrete?
Bleach can be used for cleaning concrete since it works well with mold or mildew on both unsealed and sealed surfaces, however, it can’t remove efflorescence off concrete. Full-strength bleach shouldn’t be used on the concrete surface, otherwise, it can damage them. Bleach should be mixed with water in ratio 2:1 and applied to concrete with a mop, let to sit on the surface for 10 minutes, then rinsed with a pressure washer.
4. Can I spray concrete cleaner with my pressure washer like soap?
No, concrete cleaners can’t be sprayed using a pressure washer because they can’t create bubbles and lather. Acid, alkaline, enzymatic, and bacterial concrete cleaners may damage the pressure washer soap tank or the pressure washer pump. A pressure washer should be used solely for rinsing the concrete cleaner off the surface.
5. Can you use chlorine to clean concrete?
Chlorine can be used for cleaning concrete under the condition it is not mixed with other cleaning agents.
6. What can I use to clean concrete driveways?
Bioremediation cleaner should be applied on concrete driveways to remove oil stains. Hypochlorite-based concrete cleaners are efficient in removing algae and moss off the concrete surfaces. Acidic concrete cleaners should be used for deep cleaning concrete driveways and removing efflorescence.
7. Does Dawn remove oil from concrete?
Yes, Dawn does remove oil from concrete when mixed with hot water and applied to stains. However, concrete cleaners can be more efficient with cleaning concrete and removing oil and other types of stains.
8. What is the fastest way to get oil out of concrete?
The fastest way to get oil out of concrete is to apply a concrete cleaner to the surface, scrub it using a brush, and rinse the cleaner off after about 10 minutes.
