Diamondbrite degreaser, £9.08

Tested by Dan Sutherland

Time tested: Ten washes Degreasing bike parts is one of my least favourite jobs, but this makes it a doddle. Simply spay on, mildly agitate unwanted muck and watch as the formula removes the stain before your eyes. Simply spray off any residue with a hose and it’s job done. The only downside is the pungent smell it gives off.

Verdict ★★★★★
