How to Clean Brick Floors (Indoors and Outdoors)

That rustic look is worth the effort.

Brick floors are easy to maintain, but are you cleaning them enough? This type of flooring can begin to look dirty quickly if not kept well.

Dirt and grit can act similar to sandpaper over time — damaging the seal and exposing the brick itself. This could cause your floor to degrade significantly. If you want to know how to clean brick floors the right way, you’ve come to the right place.

Brick floors can bring a rustic feel to any home — and truth be told, brick is relatively easy to clean compared to other floor types. If yours are sealed, you won’t need to worry too much about water exposure or stains. However, brick floors do require daily maintenance to look their best.

Vacuuming or Sweeping Brick Floors

Brick floors should be vacuumed or swept daily to remove dirt and grit. You can sweep with a regular broom. Be sure to pay close attention to the mortar between the bricks as there tends to be more dust and dirt hidden.

For a more thorough clean, choose a vacuum set for hard floors. If it has a soft brush attachment, use it to clean up fine dust and pet hair further. Avoid using hard attachments such as beater bars because these can damage the seal, brick, or mortar.

Unsealed brick tends to create a significant amount of grit, especially in a high-traffic area. This can damage other areas of the house such as carpets, tiles or hardwood. Thankfully, sweeping or vacuuming daily can help to reduce the amount of grit.

How to Mop Brick Floors

1. Choose Your Cleaning Solution

For brick floors, it is best to use a mild alkaline cleaner. You can choose a commercial product such as Better Life. This natural product is safe to use on hard floors and other sealed surfaces.

There are also some very useful home-remedies to try out, including:

  • Borax: Fully dissolve two tablespoons of borax in a gallon of water. Borax is a strong alkaline when undiluted, so use only a small amount on your brick floors.
  • Baking soda: Combine two tablespoons of baking soda in a gallon of water — mix well to dissolve the powder fully. Baking soda is also alkaline, but milder than borax. It’s excellent at removing tough stains and odors.
  • Vinegar: Pour half a cup of vinegar into a gallon of water and stir to combine. Vinegar is a natural acidic cleaner. It works great at adding shine, neutralizing odors and disinfecting surfaces.

2. Mop the Floor

After choosing a suitable cleaner, it’s time to start mopping. If you choose a commercial product, mix the solution as directed on the label.

When you’re mopping brick floors, it’s essential to use a damp mop. After soaking the mop in the solution, wring it out as much as you can. A spin mop can be the perfect tool for this job since it easily wrings out most water.

Use slightly more force as you sweep the mop back and forth on the bricks than you would on other floor types. This will ensure that you get into the tiny crevices between the bricks.

Avoid using sponge or flat cloth mops since these won’t hold up to the rough surface for long. Instead, choose a mop with microfiber strings. If you encounter stubborn stains or dirt, use a stiff nylon brush to scrub it thoroughly.

Quick Tip

As you mop the floor, check the water frequently. If it begins to look murky or dirty, consider dumping it and make a new batch of solution. Mopping with dirty water can alter the end result.

3. Dry the Floor

When you’ve finished mopping the floor, use a soft towel or cloth to remove any excess water. Pay close attention to grout lines and crevices to avoid any damage caused by leftover water and cleaner. Drying the floor thoroughly will also help to prevent any frustrating streaks or smudges.

Cleaning Brick Floors With a Steam Cleaner

Steam cleaners are a great tool to have in your home. They can be used on most surfaces around the house, such as kitchen counters and bathroom tiles. These machines are also excellent at deep cleaning brick floors — especially when you need to remove spills and stains.

The steam from the cleaner will get into the tiny pores of the bricks and force dust, dirt and moisture out. It will also help to remove odors and disinfect them without the need for any chemicals. Steam cleaning is an excellent way to prepare your floors before sealing or resealing them (1).

Why so Much Dust?

A common complaint about new brick floors is a significant amount of fine dust that tends to appear from the surface. This dust is usually pale in color and very fine. It can cause quite a mess when dragged to other areas of the house.

This happens because some bricklayers use muriatic acid to clean the bricks after they’ve been installed. Muriatic acid is hydrochloric acid. This chemical is highly corrosive but effective at cleaning surfaces such as concrete and brick (2).

Muriatic acid interacts with the limestone grout or mortar commonly used between bricks in flooring and buildings. So, the pale or white dust you see is the result of the muriatic acid extracting lime from the grout.

To eliminate the white or pale dust, you’ll have to keep flushing the bricks with water until the muriatic acid is gone. Fortunately today, most bricklayers use a more expensive commercial product to clean the bricks after installation. These are easier to wash off and won’t cause as much dust.

Dealing With the Grout

The grout lines are the most vulnerable part of the brick flooring. Grout is highly absorbent and will soak up liquids and spills. This will not only lead to a discolored grout, but can also damage the bricks.

Sealing the grout is the best way to avoid anything seeping into the lines or bricks. It’s a good idea to seal it once a year to keep it protected.

If you notice stains or discoloration in the grout, you can clean it using a commercial product. You can also create a paste using equal parts baking soda and water. Apply the paste and scrub with a grout brush until it’s clean and then wipe with a cloth when finished.

A steam cleaner is also highly effective at cleaning grout lines. However, it can remove some sealers. In extreme cases, you may need to remove the grout entirely and replace it.

Cleaning Outdoor Bricks

Having brick patio flooring adds a nice touch to a green garden. However, because the bricks are more exposed to dirt and the elements, they need a more meticulous clean.

Clean your outdoor bricks using a commercial acidic cleaner or sulfate-based solution. These should be mixed and used as directed on the label or by the manufacturer.

Consider using a pressure washer to loosen dirt, mud and other grime quickly. But be careful as hard scrubbing and even high water pressure can cause scratches to the bricks.

Always keep the washer at a safe distance when using. For extra safety, opt for flat or fan nozzles as these are softer than one line sprayers.

Does Brick Floor Need to Be Sealed?

Similar to natural stone floors, brick is porous and will absorb liquids if left on the surface. Unsealed brick flooring can also feel more gritty. Worse still, the dust can be tracked from one room to another.

There are two types of sealers you can use on brick floors. The first is a penetrating sealer, which gets absorbed by the brick and clogs the pores from within. This makes it nearly impossible for any liquid to penetrate and cause damage.

The other type of sealer is a film-forming product. This is applied to the top of the brick and forms a glossy film that is water- and stain-resistant.

A film coat is very popular among homeowners, thanks to the protection and easier maintenance. The film smooths over the tiny pores and prevents dirt and dust from hiding.

Decide Carefully

Before deciding on a sealant, however, keep in mind that it might change the look of the brick. A film-forming sealant can darken the brick by a few shades. Also, some wax sealers and polyurethane sealers tend to turn yellow over time.

A penetrating sealer will keep the natural look of the brick. However, there might still be a gritty feel to the floor.

Before applying any sealer, the floor has to be cleaned thoroughly. So if you want to reseal the bricks, start by removing the previous sealer — even if it’s old and worn out.


Washing the Brick

Brick flooring can feel very old-school, but it’s also a beautiful look in any country home or rustic household. Cleaning brick floors is relatively easy as they can take a bit of scrubbing.

Dust and grit can be a real problem when you have this kind of flooring. It often requires daily sweeping or vacuuming and a deep clean using a damp mop once a week. Seal your brick floors for extra protection, but consider how they may change depending on the sealant.
