Did a set of stairs recently in an adolescent care home. One of the girls had a turn and threw 8-10 different bottles down. Was short notice job so used what I had left of rid a gum, Chew gum remover and Cit gel (Knowing what I know now I would have gone straight for the acetone) but it all came out. The main point is, out of the three products they all worked differently on each of the polishes so it was a case of trying each one out.
They added £10 to my invoice when I got the cheque a week
