Detailed Instructions for Cleaning Brick Outside

Step 1: Look at the weather forecast

Brick should be cleaned while the temperature is approximately 50 degrees. It should ideally be overcast. Cleaning chemicals may dry too rapidly and leave behind residual stains, discoloring your brick, if it’s too hot or sunny out.

Step 2: Cover nearby surfaces with a tarp

Glass, metal, wood, and other surfaces might all be harmed by the cleaning solution you use on brick. Protect these areas by using a tarp or another covering. For example, if your property has external windows, lights, or plants, you might wish to cover them to protect them from the cleaning agents.

Step 3: Wet the Brick

Dry brick will quickly absorb the solvent, resulting in discolored brick and inadequate solvent. Before applying solvent, thoroughly spray the brick with a garden hose.

The brick should also be cleaned off of any visible dirt and grime using your garden hose. Before going on to the following phase, you should fix any serious issues with the brick.

Step 4: Make and use your cleaning solvent

Muriatic acid, a bleach solution, and soapy water are three efficient cleaning agents for brick. A bleach solution is best for mold and mildew (for the toughest-to-remove stains).

Soap (For Simple or Interior Cleaning): Simple stains on brick can be removed using a basic soap solution (such as dish soap and warm water). Even if you live in a dry area, soap and warm water may be sufficient if you don’t want to use bleach.

Vinegar (For Basic or Interior Cleaning): As an alternative to using dish soap, some individuals combine equal parts vinegar and water to create a solution that they then pour into a spray bottle. The effectiveness of this remedy in removing common stains from brick might be startling.

Bleach (For Mold, Mildew, and Moss): Exterior brick walls may be cleaned of mold, mildew, and moss with a bleach solution. Apply the bleach to the brick with a sponge after mixing a spoonful of bleach with a gallon of warm water in a bucket. To remove stains or difficult-to-reach spots, use a scrub. Spray some water on the brick to keep it moist if the bleach starts to dry on it. After cleaning the surface, use a water hose to wash down the brick.

Muriatic acid is an industrial-strength solvent that may effortlessly remove stubborn stains brought on by rust, dirt, or masonry. To construct your muriatic acid recipe, you must put on all necessary safety equipment, including rubber gloves, safety glasses, and a respirator. Add 1.5 cups of muriatic acid to a big bucket after adding a gallon of warm water to it (you must pour the acid into the water; never pour water into the acid). Apply the solution on brick by dipping a bristle brush into the acid. Gently scrub while allowing the acid to sit on the brick for a little while. Completely rinse the acid off using a hose and regular water.

5: Use a pressure washer

Brick surfaces may be thoroughly cleaned with pressure washers. A brick-cleaning solution may be added to your pressure washer. Alternatively, you can use water to completely clean the brick after using the cleaning solution in Step 4.

The brick might be harmed by excessive pressure. To protect the brick, keep the pressure at around 3,000 pounds per square inch.

Additional Cleaning Advice for Brick Exteriors

  • Mold, mildew, and moss may quickly grow on the bricks of your home if a particular side doesn’t receive enough sunshine.
  • The surface of the brick should be readily cleaned with a decent sponge; however, use a natural or nylon-bristle scrub brush for regions that are more difficult to reach, such as the crevices between bricks.
  • A wire brush should not be used since it may leave behind metal fragments that corrode and discolor your bricks.
  • If brick is loose or deteriorating, avoid utilizing pressure washers’ high-pressure setting as it might seriously harm the brick. For pressure washing brick, 3,000 PSI is the optimal pressure.
