Cleaning Brick or Stone Surfaces Affected by Smoke Damage
Procedure - Alkaline Cleaning
- Remove dry soil with a HEPA vacuum and dusting brush.
- Using pump-up sprayer and your alkaline stone cleaner, spray a 3' x 3' area (start at the bottom and work your way up).
- Using a nylon brush, agitate the sprayed area.
- Rinse with clear water.
Procedure - Acid Wash
Acid washing will remove a microscopic layer of the brick/masonry facing, making it more vulnerable to moisture. It is recommend that a sealer be applied to any exterior masonry/brick after acid washing.
WARNING: Never use muriatic acid on stone or masonry. Acid will etch most stone/brick/masonry surfaces. Avoid uneven or prolonged contact because etching, uneven cleaning, or streaking can result.
- Prepare a diluted solution of your acid-based cleaner.
- Using a pump-up sprayer, spray a small area (no larger than 3' x 3'). Immediately lightly agitate the area.
- Rinse well with clean water
