I live in a very hard water area and don't have a water softener - getting one is not currently an option.
Under the loo rim has limescale that nothing I've so far tried can shift and it's starting to really bother me. Does anyone have a super limescale busting tips? I've tried soaking it in supposedly limescale tackling toilet duck, leaving and then scrubbing. Same with spray on limescale remover. No luck. Anything else I could try?
