Domestos Original Thick Bleach eliminates 99.99% of bacteria and viruses, leaving surfaces disinfected. The formula contains anti-limescale active molecules that stick even below the waterline, helping to prevent the build-up of limescale. Making white surfaces whiter and eliminating odours for lasting freshness, the bleach is suitable for use as a multipurpose cleaner when diluted. For use all around the home, as a bathroom cleaner or even as a drain cleaner (including homes with septic tanks), this Domestos bleach is supplied in a pack of twelve 1.25 litre bottles.
