Removing Efflorescence from Concrete, Stone, and Brick

Efflorescence is a common issue found on brick, concrete, natural stone, and many other surfaces. Efflorescence is a fine, white, powdery deposit of water-soluble salts left on the surface of masonry as the water evaporates. Efflorescence can not only be removed with basic cleaning tools, but also can be prevented with proper sealing.


Rinse your surface thoroughly with water with a hose power washer, or high pressure sprayer. After your surface has been rinsed with water, put on rubber gloves and apply Glaze ‘N Seal Efflorescence Remover in a small test area. Glaze ‘N Seal Efflorescence Remover can be diluted with up to 5 parts water.

Apply Glaze ‘N Seal Efflorescence Remover to your surface rigorously with a firm bristle brush and let it it sit 2-5 minutes. Do not allow the solution to dry on the surface.


Using a mop or wet vac, clean the solution off your surface and rinse with clean water. After cleaning, be sure to neutralize your surface with Glaze ‘N Seal Neutralizing Rinse before sealing.


Efflorescence commonly re-appears, so be sure to seal your surface post cleaning or consistently clean your surface.
