Don't know if it will work for this particular problem, but the best cleaning solution I have found is to dilute dishwasher tablets in hot water. This seems to clean pretty much anything I have tried it on do far. Another thought is that stuff you can buy that covers over stains from damp on ceilings - I think that it is white though - it comes in a spray that you get from diy stores.
