Cement Away
This is a market-leading safe acid, used for removing grout film, lime mortar and cement residue from surfaces, both internal and external. Cement Away can also be used to remove efflorescence encrusted / ingrained dirt plus lime scale / calcium deposits.
Cement Away is ideally suited for use on acid-resistant surfaces such as ceramic and porcelain but can also be used on brick, clay, concrete paving and most natural stones.
