In the past, I've only ever used soap/car wash/sponge/WD40.
(Apart from recently, when I've used that fly dissolving stuff)
Last night, I spent an hour cleaning the Fazer, most of which was on the back wheel. (The rest wasn't particularly dirty) It looks like new. So today, I bought a big bottle of Muc-off. Hopefully, next time, I can just spray the stuff on, juggle it around with a brush, and hey-presto - shiny new bike

We will see.
