We have a plain apple green (i.e. shows every mark) sofa - fabric unknown but a kind of synthetic coarse linen-effect weave. Somebody - naming no names, but he knows who he is - has spilt their dinner on it.
To be honest, it was looking a bit grubby anyway, and now the whole thing needs a d*mned good clean. We don't have a wet&dry hoover, and the marks are greasy.
Any suggestions on how to go about it would be gratefully received.
