Well, various cleaners, simple green is one of my favorites for plastic and rubber. It is mild enough that it doesn't damage parts, sometimes requires more than one application. Windex on chrome after you cleaned everything up leaves no streaks. If your chrome is pitted some you will need a polishing paste (lots of brands out there). If you have a shop vacuum cleaner used if first with a dry old toothbrush or similar tool to knock loose the big chunks of dirt and junk and then suck it up with the vacuum. A small brass bristle brush shaped like a toothbrush (can be purchased at the hardware store) can be used to get old burnt paint off the heads near the exhaust port and also to clean off rust on the exhaust manifolds but only do that if you intend to re-paint the same day. Then, if you do, mask everything else well. A few small rattle cans of paint should do for touch up purposes, won't last forever but will surely last a while, I would re-paint that alternator bracket satin black, I think that was more original looking and contrasts with the gold engine and chrome accessories well. Any way, getting carried away here. Have fun.
