Power Keen Corporation’s Right Off has been the best selling concrete removal product in the Ready Mix Concrete industry. Right Off’s “original” formula was designed to meet the heavy-duty cleaning requirements of the Ready Mix industry without the heavy-duty corrosive effects of harsher cleaning acids. As a phosphoric acid-based cleaner, Right Off does not contain any muriatic acid, hydrochloric acid, salts, or chlorides, and it is 100% Biodegradable, Non-Corrosive, Non-Regulated, and a Non-Skin Irritant.
