Hi there so a few years back I had my vintage Ercol 3 piece suite reupholstered in cream (yes, I was young and stupid). It picks up dirt really easily but want to keep it as do love the colour. We had throws on it to protect it but looks so messy! Dp has now banned the throws. How can we protect the fabric? I don't think it is made of anything hi tech that would repel dirt. Is Scotchguard used for this kind of thing? Any help would be really gratefully appreciated...
