Mechanics and Fixing Any Questions Answered

We couldn’t get it to stick to the chain it prefers legs and furniture

A good friend of mine engineered one of their cleaning products, and it's absolutely useless at removing any of their other products

Yes, almost impossible to eradicate later, as others remark. When it comes to cleaning up the cassette cogs, a wire brush is your only friend

Muc off wet and urban are the worst product to hit the cycle industry in maybe 20 years? Search back and you'll see me and others ranting about it for 5 years.

Have tried to talk to muc off on a commercial level (we're a shop and workshop and know a LOT of other mechanics around this small isle) and their only on the record response was 'your customers are using too much of it'.

You'll find LOTS of other bike chain lubes now also have the same issue. IF you see the small blue star on the packaging signifying its made of Bio oil/renewable products. DO NOT USE IT. Seen it on at least ten different brands now, all do the same, turns your drive into one gigantic tacky black solid mass that won't change gear right, coats your frame and only thing that really takes it off is.....
Cyclon Bionet chain cleaner (dutch brand), soak it and a very stiff brush or a wire brush. If its got on your frame and been left for months your only hope is to basically cheese grate it off with a plastic tyre lever and then use the Bionet.
Also found commercial grade paint thinner and Xylene will take it off. But will also ruin your skin, bad for the environment and will likely damage your paint or bike components

Judging by the smell and consistency I think its literally vegetable oil with a modifier, thats all it is.

ANY environmental benefits of that 'bio oil' is totally wiped out by the fact we are seeing brand new reasonable quality bikes (tiagra 10, 105 11, sram force etc) needing a new chain within 400 miles due to the massively increased wear rate, seen dozens if not more rear mechs ripped off due to jockey wheels totally caked within a month or so of use. And the really strong products and labour required to remove it.

Would really like to know muc off's commercial stance on this product. Are they secretly owned by 'big bike chain, cassette, chainrings, rear mech and mech hangers LLC'?

It seems to play especially badly with the bright finish on campy chains and cassettes. I quickly gave up and switched to RocknRoll

Yeah really noticing this more recently as if something has changed in their mix. Never was the best but don't remember it being like this.
