Nofairy liquid
bad for paint , bad for rubber
muc off is brilliant, i used to just use fairy liquid and was very sceptical about muc off, i thought it was just expensive fairy liquid but it does work and it works well,it also leave a thin coating to help stop muc sticking.
Muc off is brilliant indeed, but did you know that it also strips/dims the colouring of your paint little by little?
It's recommended that anodized bikes do not use Muc off as it strips the coloured dye away rather quickly
