S100 Chain Cleaner - 300ml

This stuff is great.
It is more of a gel than a spray, so it doesn’t go everywhere.
I just used it with the brush and cleaning my chain took about half the time it usually takes me.
It cleans very well and you don’t really need to scrub very much at all.

Hard to tell how much it has ‘cleaned’ the chain, does seem to help loosen grease (mainly the chain lube!). Hasn’t helped with stopping the chain from corroding,

The colouration of the spray helps when determining when the whole chain has had an application.

Been using this product for years, does exactly what it says on the tin, easy to use, great results.
