DS2 'accidentally' sat on one of my newly reupholstered ercol armchairs having put sudocrem on his bottom (don't ask me why, I was out collecting DS1 from cubs at the time). From the look of it DH has 'helpfully' scrubbed it with a wet cloth, so there will be a large water mark with scrubbed in sudocrem in the middle. Lovely. Can anybody tell me is rescue possible? And if it is, how do I do it?
