How to Get Heavy Grease Stains Out of Victorian Brick

Blot as much of the grease from the brick as possible if it is fresh. Use rags to soak up the grease without rubbing.

Spread a layer of whiting powder over the grease spot. Use your fingers to rub it into the brick. Whiting powder is similar to a fine chalk and is available at most home improvement centers.

Let the whiting powder sit on the brick overnight. Brush it off the next day.

Cover the remaining grease spot with liquid laundry detergent. Allow it to remain on the surface for 15 minutes, and then scrub the brick with a wet scrub brush.

Rinse the brick with clean water. Allow it to air-dry.

Mix 1 gallon of hot water and 1 cup of trisodium phosphate into a bucket. Scrub the TSP mixture onto the brick using a scrub brush. Let it sit on the brick for 10 minutes, and then continue scrubbing until the grease is gone. Rinse the brick with clean water and let it air-dry.

Make a paste of 6 parts glycerin, 6 parts hot water, 1 part sodium nitrate and a sprinkle of whiting powder if any of the grease remains. Spread the paste onto the grease-stained brick. Let it sit for one week then apply a new layer of the paste as it dries. Brush off the dried paste after a week then rinse with warm water.
