Factors to Consider When Choosing a Concrete Cleaner

It’s time to get serious about cleaning concrete surfaces. And while it may seem like a simple task, choosing the right cleaner can be a tricky business. When choosing a concrete cleaner, or any cleaner for that matter, there are several factors that you should consider to ensure that you get the best results. These factors include:

  • Type of Stain: Different types of stains can be difficult to remove, but with the right cleaner, you’ll be amazed at what you can accomplish. Stains from oil, grease, and other automotive fluids, for example, require a degreaser to break down the grease and lift it off the surface. Rust stains, on the other hand, require a rust remover specifically designed to dissolve and remove rust. And let’s not forget about stubborn organic stains, like algae, mildew, and mold – for these, you’ll want a cleaner with an appropriate biocide to effectively remove the stain. So, before choosing a cleaner, it’s important to identify the type of stain you’re dealing with to ensure the best results.
  • Surface Type: Concrete and brick surfaces come in many shapes and sizes, from concrete driveways and patios, to brick walls and fireplaces. It’s important to choose a cleaner that is designed for the type of surface you’re cleaning, as some cleaners can be too harsh for certain surfaces, leading to damage or discoloration. For example, some concrete floor cleaners may be too strong for use on delicate brick surfaces. So, make sure to select a cleaner that is appropriate for the type of surface you’re cleaning, and always read the manufacturer’s instructions before use.
  • Strength: When it comes to cleaning concrete and brick surfaces, strength matters. Some cleaners are designed to be stronger than others, so it’s important to choose a cleaner that is appropriate for the type of stain you’re dealing with. If you’re dealing with tough, stubborn stains, you’ll want to choose a cleaner that is specifically designed to tackle those types of stains. And if you’re dealing with lighter, surface-level stains, a milder cleaner may be all you need. So, make sure to select a cleaner that is appropriate for the level of stain you’re dealing with to ensure the best results.
  • Environmental impact: it’s important to consider the environmental impact of the products we use. Some cleaners contain chemicals that can be harmful to the environment and human health, so it’s important to choose a cleaner that is environmentally friendly. Look for cleaners that are biodegradable, and free from harsh chemicals. Not only will you be doing your part for the environment, but you’ll also be making a cleaner, healthier space for you and your family. And who doesn’t want that?

Common Types of Concrete Cleaners

When it comes to cleaning concrete and brick surfaces, choosing the right type of cleaner is crucial. There are several types of concrete cleaners available, each specifically designed to tackle specific types of stains. Understanding the different types of concrete cleaners is essential to making an informed decision and achieving the desired cleaning results.

  • Acid-Based Cleaners: Acid cleaners work by removing a thin layer from the concrete’s surface. This makes them particularly effective at removing surface-level stains. Traditional acid-based cleaners use muriatic acid or phosphoric acid and are applied directly to the stain. When an acid is applied to concrete, it reacts with both calcium hydroxide and calcium carbonate found naturally in concrete. While this reaction can help to remove stains and contaminants, if acid washing is too frequent or your acid is too strong, it can damage your concrete, brick, or pavers. Polished surfaces and colored concrete should not be treated with acid, as it would likely etch the surface or make the color dull. It’s important to note that both muriatic and phosphoric acid can be harmful if not used properly and should be used with caution.

*PRO-TIP* – Look for the next generation of low-pH cleaners that do not use acid – stronger than old-school muriatic acid but safe for use indoors.

  • Alkaline Cleaners: Alkaline cleaners are a type of concrete cleaner designed to to remove tough, deeply ingrained stains for concrete, pavers, and brick. They work by using a high pH solution to dissolve and lift stains, breaking down the bond between the stain and the surface. Alkaline cleaners are typically, composed of a combination of sodium hydroxide, surfactants, and water, and are applied directly to the stain. The alkaline solution reacts with the stain, breaking it down and allowing it to be rinsed away with water. Alkaline cleaners are especially effective for removing oil and grease stains, and are commonly marketed as concrete degreasers. They are often used as a pre-treatment for surfaces that are being cleaned with a pressure washer, as the high pH solution helps to loosen and remove dirt, grime, and other debris.
  • Solvent-Based Cleaners: Solvent-based concrete cleaners utilize various types of solvents to dissolve and remove stubborn stains and buildups from concrete surfaces. Solvents work on a wide variety of stains including paint, graffiti, adhesives, mastic, and topical concrete sealers. However, due to the strong chemical composition of some solvent-based cleaners, they should be used with caution and only in well-ventilated areas. Some solvents can be harmful to the environment and to human health if not handled and used properly. Fortunately, there are safer solvent-based cleaners available. 
  • Detergents: Detergent-based concrete cleaners are a type of cleaner that utilize a soap or detergent solution to remove dirt and grime from concrete surfaces. These cleaners work by breaking down and lifting away dirt and grime from the surface of the concrete, making it easier to rinse away with water. Detergent-based cleaners are typically less harsh and more environmentally friendly than other types of concrete cleaners, making them a popular choice. They work best on concrete surfaces that have not been severely stained or have a buildup of tough substances, such as oil or grease.
