Only used once so far so still playing with mixtures. I've started with a mix of 150 ml to 1 litre water which seemed to work well after a very muddy ride. Certainly as well as the "M" brand rival, and probably better on chain dirt / grease.
Nothing yet.

Excellent cleaner and eco friendly, what more could you ask for. Much better than another "blue" cleaner I used which actually destroyed the grease in my rear wheel hubs as well, which is obviously not good.
Nope, no bad points. Well satisfied customer
