id use either castrol contact cleaner or maxima brake cleaner(MAXIMA SMELLS OF ORANGES mmmmmmmmmmmmmmmmmmm nice) there also both good for putting grips on/off(it dries)removing the scum after you take stickers off,before fitting sticker,cleaning rims etc,there great,carefull with the maxima on paint though,it must be a bit stronger than the castrol as i tried it on a painted item and it started to remove it,so id go with the castrol,should be able get it from halfords etc,
ive been using it for about 15 years
