In most cases, clean lightly soiled concrete or interior concrete using a pH neutral concrete cleaner. Acidic cleaners remove efflorescence stains and other substances that are dissolved with acid. Alkaline cleansers are helpful for removing grease.
In all cases, use a brush or cleaning machine to scrub the concrete. In the case of severe build up and stains, treat an area twice before rinsing it well. Then, treat surfaces with a concrete sealer appropriate for the application.Learn more about Cleaning
