Astonish Bathroom Cleaner Spray White Jasmine & Basil 750ml Our Bathroom Cleaner makes short work of cleaning the tub, but the rest of the bathroom too. It's tough on soap scum, watermarks and limescale, so you're left with a streak free shine. Ideally used on baths, washbasins, taps, glazed ceramic tiles and showerheads. Spray foam and leave for 2 minutes before wiping with a clean damp cloth or sponge. Rinse if necessary with clean water. For heavy limescale deposits repeat treatment as necessary.
