I have a new toilet and bought a different cleaning product to normal as they had no bleach at the time, it was a bottle of thick yellow toilet cleaning gel from Asda. I stupidly squirted it around under the rim afterwards and left it to drip down thinking it would give an extra clean and sparkle. Now I am left with lots of awful yellow streaks which I can't remove, I have tried rubbing them with white wine vinegar and normal thick clear bleach but they actually look worse and the yellow is looking more yellowy brown the more I try to get rid of the marks. Could anyone suggest anything else I can do please?
