How to Clean White Soil Leaching Off Patio Bricks

A white area that begins to form on bricks--as well as other masonry items--is often thought to be a form of soil leaching or mold. However, these white spots or streaks are probably efflorescence. Masonry items are made from raw materials that contain salt. The salts--trapped inside the masonry--dissolve into water. When the salt water makes its way through the pours of the masonry, it leaves a white trail or streak.

Plastic tarp
Rubber gloves
Broom
Water hose
Water
Muriatic acid or white vinegar
5-gallon bucket
Stiff bristled brush or a brush broom
Baking soda

Instructions

- 1
  Cover nearby plants, shrubs and greenery with a plastic tarp to protect them from the cleaning solution.
- 2
  Equip yourself with rubber gloves. Remove any surface dirt or debris from the patio bricks using a broom. Hose the bricks down with a water hose.
- 3
  Create a solution of 10 parts water to 1 part muriatic acid in a 5-gallon bucket. Muriatic acid is dangerous and should only be used when diluted. For an all-natural alternative to the acid, use undiluted white vinegar.
- 4
  Allow the solution to sit on the bricks for 10 minutes.
- 5
  Submerge a stiff bristled brush or a brush broom in the solution. Begin scrubbing the efflorescence with the brush.
- 6
  Rinse the patio bricks completely with a water hose.
- 7
  Sprinkle baking soda onto the bricks and scrub using a clean scrub brush or brush broom. The baking soda will neutralize the acid.
- 8
  Rinse the patio bricks once more with a water hose.
