Ages ago, someone left a couple of tins on a damp laminate type worktop, and it left 2 dark circular marks on the surface. Tried all kinds of cleansers but can't shift it.
The same someone constantly left wet-bottomed saucepans on the electric hob (solid type) and most of the hobs have developed a lovely layer of rust too.
Is there anything that will get those marks off? We're renting, and the oven came with the house so want to clean them up as much as possible. Thanks for any advice.
