What can i use to take nail polish off a sofa chair?

Question:

Answers:
first of all try acetone free nail polish remover on a NON VISIBLE part of your sofa, ie under the cushions or somewhere you won't see it - if it damages the cushion cover it won't matter too much and you won't have caused more damage

you could try putting clear polish on top of the polish that is dry and wiping both off together - again i would try this on a spare bit of material before you try it on your cushion

failing that, try getting a professional sofa cleaning company in or see if you can get a replacement cover from the shop you bought it from
