Bilt-Hamber auto-wheel
Price: £12.95 | Size: 1l
One of the first of the new wave of ‘purple’ cleaners hangs on to its crown, but it was close. Even with the lightest of agitation auto-wheel made good progress on our filthy trims, leaving just a few streaks. You need to let it work for five minutes until it turns dark purple. Then, a pressure washer blast or brushing is all that’s needed. It’s not the cheapest of those tested, but does include a wheel brush.
