Chine Shine, which is available in 2, 5 and 20lt containers, is brushed on to the surface, left for 10-15 minutes and rinsed with fresh water. It’s a thin gel, blue in colour, and it went a long way. The results upon rinsing were comparable to the best-performing products we tried. It’s also the cheapest per litre of the products on test.
