Autosol is metal polish, for that shiny downpipe look.
There are better examples of shiny downpipes, kwak zzr springs to mind.
I just use autoglym shampoo and water on wheels, had to use a bit of chain cleaner/degreaser when I used to get fling from chain lube (I now use dry lube but I'm a bit stupid and don't know where I've lubed, so my chain is in a terrible rusty state).
After you've given it a wash, dry the bike off with a microfibre cloth then wax, and wash it after every ride!!
