Grill bricks are mostly pumice, a naturally occurring lightweight rock. Some are made from compacted sand of fine grains so as to improve the abrasive capability. Grill bricks have the advantage of being harmless, both to the environment and to the person using it to clean. The material that makes it is used in a number of other consumer products as an abrasive, such as in toothpaste.

During use, the material that makes a grill brick breaks down to grit, coming off the brick to produce a paste that further helps to improve its cleaning properties. The grit works to dislodge stuck food particles and carbon from the surface being cleaned. The grit, together with the dislodged dirt, is then rinsed off to reveal a clean surface.

A grill brick, when used for cleaning, has the following advantages:

  • Is nonporous and will not absorb carbon or food odors
  • Will not become clogged with grease
  • Wears to a new surface each time it cleans
  • Is all-natural and, therefore, not toxic
  • Doesn’t damage the coating that makes griddles non-stick
  • Has mild abrasive properties and so won’t result in scratches
  • It can be used on hot griddles or grills without any problem
  • Doesn’t require any special storage or care

How to Use a Grill brick

How to Use a Grill brick

Grill bricks are used to clean grills and griddles of leftover grease after cooking oily foods, carbon deposits as a result of overused grill or griddle, rust, paint, lime, and any other kind of stains that need to be removed before the grill or griddle is usable.

You can use a grill brick on its own, or in combination with other mild abrasives. For ease of use, a handle made of aluminum is always attached to the brick by means of removable screws.

It makes using it on hot surfaces safer, plus you don’t end up getting your hands dirtied by the paste of grease, carbon, and grit that forms during cleaning. The handle comes already attached, or you can do it yourself.
