HG Blue is a highly concentrated phosphoric acid based cleaner that is non corrosive, biodegradable and safer to use than hydrochloric acid. Does not give off fumes. It safely and effectively 'deep cleans' glazed and unglazed ceramic floor and wall tiles in swimming pool surrounds, shower areas, changing rooms and toilets, particularly if the tiles have started to become slippery because of the build up of body fats and oils. It also removes rust, dirt, lime scale and calcium stains on shower heads, WC pans, baths, taps and wastes.
