My new to me Rainbow E Series single speed was delivered yesterday. As you can see, it needs quite a bit of cleanup. It was loaded with spider webs, and dead spiders in the water pan. It also looks like it was stored with dirty water in the pan, judging by the dried caked on mud. It did come with a 4 quart pan, so that is a plus. What would be the best way to clean up the white scrapes off the dolly and power nozzle?
