You can clean the outside with LA Totally Awesome cleaner which is at the Dollar Tree stores in North America. I don't know where you are from. Just spray it on and let it sit for a couple minutes and use a toothbrush or brass brush and it will look nice. The insides I use acetone. Either way, I would spray some WD 40 or something to stop oxidation. I don't see a muffler, but ya, you could make a plane for it!!! It adds another couple dimensions to it compared to cars. You just can't pull over and think when you are moving.
