Muc-Off

This product has some bite to it, good aqueous cleaner...BUT...it's obviously very alkaline and if you leave it too long on painted wheels or casings it will leave them dull.

 

I've used it for a while.It's quite good but for stubborn stuff you'll still need to give it a bit of a scrub.
The problem with bikes is there's a lot of nook a crannys.
As Acko said be careful with the wheels,it can leave them a bit dull.

 

I use it and like it although I use WD 40 on a cloth to get the oil and crap off the back wheel, swing arm, and number plate.

 

Never liked Muc-Off because it is very watery, I used to use the Hein Gericke gel cleaner but now use S-Doc, it's expensive but does a bloody good job.

 

Personally, I've never found the need to use Muc-Off or similar for my bikes. Not a criticism of those who have used it, of course!! But, instead of using WD-40 for greasy bits, I have found Mr Sheen, or similar, to be excellent for cleaning up rear wheels and the like. Makes the bike smell nice as well!! Also good for degreasing hands!!
