Everbuild has launched Cemstrip, an environmentally-friendly biodegradable cement remover with a citric acid-based formula.
It can be used to remove wet and cured cement and concrete as well as mortar stains on a variety of surfaces.

As it does not contain hydrochloric acid, Cemstrip can be used on most metal surfaces. The highly-concentrated formula can be diluted by up to 10 times with water to suit the relevant application.
