Hose it down, then wash it with a bucket of warm water and good carwash soap (meguiar or turtle wax) with a clean soft sponge. Then dry it with a good clean chamois.
Apply good wax (I use Meguiar gold class) on the painted plastic parts, let dry (10-15 minutes minimum), then wipe off with a clean microfibre cloth ($2 at Bunnings, can be washed with hot water and let dry).
Wipe unpainted metal parts (swingarm) with CRC or WD40 to clean any oil/chainlube residue.
Wipe the black unpainted plastic parts (mirrors etc) with a cloth sprayed with Armorall plastic protectant.
I'm not sure about wheels. I'm still fooked with cleaning wheels. I hate it. I normally just ignore them.
Don't do anything to the tyres. Leave them alone.
Methods I use 10 years so far. Still brand new look.
Happy to show results if you want.
