What is the difference in the active chemical agents in simple household bleach and 'toilet cleaners'?
I have been trying to get rid of a 'toilet stain' for ages. Brushing and Harpic etc. had no effect. The other day, in desperation, I tipped some simple 'own brand' bleach down and the stain just disappeared.
Modern 'School Chemistry' is of no use at all in finding out about this but someone (possibly as old as me) must know the answer to this.
