Hi ...Nail varnish was spilled on my cream bottom sofa cushion. I tried to follow the online advice and dab it with acetone and then put it through the wash. But when i took it out of the machine the colour had completly changed - before it was cream and now its a washed out off white with dark splodges all over it. What can i do ?? IS there anyway to get it back to the previous colour ? thanks in advance for any help
