How do I get rid of a blue toilet bowl stain

[madmaz50]

The stain is around the edge of bottom of the toilet bowl. I have tried the usual toilet cleaner (with 100% limescale remover) and bleach, neither have worked. Any ideas ?

CILLIT BANG !! Sorry, just had to shout it, like the annoying man on the telly. I'm surprised bleach hasn't removed it. What about some of the old remedies like lemon juice or bicarb? Good luck

OK get a bike pump and a bucket suck out all water from bottom bar a little.
use a pumice stone it will not scratch porcelain and it will come up like new :)

Try a paste of table salt and water applied over the stain and leave overnight then scrub in the morning.
