Can I Bleach My Concrete Kitchen Counter?

Cleaning

Bleach is not recommended for use on concrete countertops. The countertops have a clear sealer covering the surface and harsh chemicals, such as bleach or ammonia, can damage that surface. Abrasive cleansers and scrubbers should not be used, and acidic products should be avoided because they will dull the surface. Soap and water is the best cleaner, but other household cleaners can be used. Most light stains can be removed with mild cleaners

Because of the porous nature of concrete counters, they are easily soiled and stained. That is why they are sealed immediately after installation. The sealant will extend the life and beauty of the concrete countertop so take care not to damage it.

Cutting on concrete is not recommended because it can damage the sealant. For the same reason, keep hot pots and other hot items off the countertop. Acidic items, heavy oils and fatty substances should not be left the surface.

Spills that remain for an extended time on the surface of a concrete counter (as well as standing water) can leave stains or marks. So it is best to wipe up all liquids as soon as possible.

Manufacturers recommend polishing concrete countertops at least four times a year with a paste wax, which will preserve the color and surface. Countertops also can be resealed, if the need arises. Keep the countertop clean to help preserve the beauty and richness of the color.

If the concrete counter does get stained, it is best to contact the manufacturer. The surface will have to be sanded with a fine gauge sandpaper, then resealed and waxed. Because of the color and shading variation in each countertop, this is best left to the experts.
