When tar sticks to a porous material like brick, it is very difficult to remove without a chemical agent. The chemicals used in cleansers like Jasco Bix or Prosoco are caustic. Using this cleaning agent requires taking care and wearing protective gear and old ratty clothes. Prepare to lose brushes and scrubbers to the chemicals, as they tend to break down the brush hairs during use.
Things You'll Need
Jasco Bix or Prosoco
Rubber work gloves
Metal bucket with warm water
Shop towels or rags
Ratty work clothes
Put on the eye goggles, old clothes, apron and rubber work gloves. Take the cleanser outside and pour the substance from the can into a metal bucket.
Dip the scrub brush into the chemical and scrub the brick in a circular motion for two to three minutes. In a separate bucket, pour warm water. Dip rags into the water and wash the tar remover off the tarred brick.
Move the the next section and repeat the Steps 1 and 2 until all tar is removed from the bricks.
Hose down the bricks and direct the rinse water to a drain. Let the surface dry, then hose it down once more, again directing the water toward a drain.
Jasco Bix and Prosoco are highly caustic substances and require care when using. Keep pets and children away from the area while you are using such products. Keep the area in quarantine for two or three days after the use to let the chemicals dissipate.
