How to remove hard water stain from toilet bowl?
For toilet bowls add 1 liter of vinegar to the bowl itself and scrub with a toilet brush to dissolve away hard water stains that has built up over time. Also, by adding 1 liter of pure vinegar to the cistern (tank at back of toilet) this not only removes any stains from there but also removes any from underneath the rim on the next flush! Sometimes stains are extra stubborn – for this make a paste of white vinegar and baking soda and scrub gently with a soft brush or sponge. Never use an abrasive cleaner like scouring pads, powders or steel wool as this will scratch the surface.
