For down pipes - "Bar keepers friend" from Asda. Its ametal cleaning product. Make it into a paste, spread on downpipes. Leave to dry, then use fine wet and dry paper. Finally polish with autosol.

For general engine cleaning - clean with de-greaser, then WD40 to wipe down after.

For nuts & bolts etc - I have some cleaning pads, whack them in the drill / dremel, put dollop of autosol on nut and go crazy for a few minutes.

Then usual WD40 of wheels etc and polish up plastics.

One other thing I did after long winter with SV, was to remove all plastics and I mean ALL.....so nose cone, rear plastics, all of them....came off then gave it a good spring clean.
