I'm happy to recommend stuff that works, every now and then i stumble across something that works so well i think i'm dreaming ! it happened last weekend, i popped into a local motorfactors to buy some engine oil and on the stand they had some muc off chain cleaner like this:
it was £9.00 and i did an impulse buy, never really used a chain cleaner before, just scrubbed it every now and then if really bad or just lubed it up after washing the bike.
this stuff is amazing ! it gunned all the crap and crud out of every link, i then wiped the chain over a few times with a cloth and applied a little lube, then wiped that off (effectively leaving the lube in the parts the cloth didnt reach.
What a difference and used absolutely no effort ! Chain is sparkling clean although nothing like this anymore
the black has long gone, feels like a rip off... not sure what the black did apart from cosmetic and now its silver and working the same
so there you go, if you want a clean chain and unsure what to use, use this muc off stuff, so simple i can do it !
