GT85, £2.99

Tester: Bruce Dunn Time tested: Three

years

GT85 is immensely useful stuff. It’s incredibly good at cleaning chains, and even better at removing stubborn wheel grime which other cleaners can struggle with, meaning that you hardly ever have to scrub and risk damaging paint. It’s also very cheap, which is good as you can end up going through a tin pretty quickly.
