sesame seed oil. yup i shizz you not, it works great
i have tried all sorts of stuff including branded sticky stuff remover, isopropyl, petrol, paraffin, you name it i have tried it.
just removed some sticker glue from a plastic spray bottle i wanted to use and i dont know why my brain said sesame seed oil but it did so me being me thought what the hell. poured some on a cloth and went to work. fekin superb, it glides and removes at the same time and is super quick unlike everything else i have tried which just makes the cloth stick and create a globby mess.
