Just wanted to recommend this Sticky Stuff Remover I bought the other day
It comes in so handy and shifts that sticky residue from stickers, labels, double sided tape etc straight away
Removes tape/sticker residue, tar, grease, chewing gum, make-up, candle wax, adhesives etc, from glass, wood, metal, work tops, fabrics, tiles and it's safe on paintwork and even skin and hair
I bought the original liquid version, but they sell a spray too.
£3.99 from Lakeland.
Def worth investing in a bottle.
