My boyfriend has a very expensive frying pan that is kind of... coloured on the outside (I don't know how to explain it.. It is a colour, not just a normal black frying pan) and the grease has gone all over the side and been burnt on by the gas. Soap and water won't get it off.. Anyone know what will ?

Hello 1985, I know the kind of pan you mean. You could try Fairy power spray.Its very good, Or give it a soak in vanish oxi. Vanish oxi brought my oven pryex up a treat, so it might just do the trick.

Depending on the surface, you could try a scouring pad and Cif/Jif very carefully.
