Standard single memory foam matress (Southport PR8)

Hi, we have a standard size single memory foam mattress. This has only been used for kids stop overs and is like brand new apart from a drink stain. We have tried everything to get it out, but no joy! It comes with a full mattress protector, bought after the spill. We would like this to go to some one in need. Collection Hillside. May deliver locally if I'm passing, but won't promise
