Think what I will do next time I get a stain (most probably will be chocolate related ) will be to spray some samples of the thread involved in the project on the fabric with some Vanish stain remover spray and then put it in water, just to test it. Then use it if need be on the project
From the sounds of things it looks like the UK equivalent of Oxiclean is Vanish ^^
