Its reactive power makes it the chemical of choice for cleaning of stained and slow flowing urinals because of urinal salt and calcium build up.

Other uses include heavy-duty masonry cleaning, preparation of masonry for painting or sealing, removal of efflorescence or mineral deposits and pH reduction in swimming pools.
