How to Remove White Chalking on Bricks

Save

Correctly identifying a mess is the key to successful clean-up and prevention. Brick walls and walkways usually develop a white, chalk-like appearance for three reasons: they were used for drawing, mold has grown on the surface or efflorescence has caused salt build-up. Identify the problem by examining the brick itself: if the white powder follows distinctive lines, it is probably chalk. Patchy areas of white and other colors indicate mold, while efflorescence has a distinct particulate appearance.

Things You'll Need

  • Protective gear
  • Brush, stiff
  • Hose
  • Water
  • Mold killer
  • Efflorescence cleaner
  • Mild detergent
  • Put on protective items, such as a breathing mask, gloves, boots, pants and long-sleeved shirt.

  • Scrub the white residue with a dry, stiff brush.

  • Hose down the wall with a concentrated stream of water. Scrub with a wet brush.

  • Clean drawing chalk with a mild detergent. Apply mold killer to mildew and other fungal growths. Use efflorescence cleaner to diminish the appearance of mild cases, in which crystals have not formed. Follow the instructions provided if using a commercial cleaner.

  • Rinse thoroughly and scrub.
