I have found this amazing hand wipes from http://www.grimeboss.co.uk
Basically it’s more courser than baby wipes, instead of using to wipe your backside (but you could if you want to but who’s to know?), one side is soft and the other is courser.
It will clean your hands after messing about with carbon brushes before you drive to the next job. It smells very er…lemony.
Costed me £5 a pack but it is great stuff.
