Tar removers have historically had a couple of issues - they 'run off' the paintwork and smell horrible. Tarmalade addresses both points. It's a thick paste based on nature's own degreaser and super-solvent, orange oil. So it clings to paintwork, giving a good dwell time, and smells of fresh oranges. In fact, it's so pleasant to use you'll have to stop yourself spreading it on your toast?
