How get I get urine stains off tiles/grouting around the toilet?

[Tryharder]

Just that really. I have a DH and 2 boys, but am naming no names. I have tried bleach and variety of strong cleaning sprays but nothing shifts it.

Grateful for any advice.

You need to re-grout or get some of the whitener from a DIY shop.

You could try making a thick paste with bicarbonate of soda and a bit of water, and scrub with an old toothbrush. I've had some success with this on a manky underside of loo seat where bleach failed!

Steam cleaner should do it

Bicarb of soda and white vinegar paste, scrub with an old toothbrush,should do the job.

A knife, so they have to sit down forever more!
