Ebay "commutator lathe" and see what people are selling. I managed to get a brilliant used Trinity one last year for about $100au delivered, say 80USD. Whenever your comm shaft is starting to go out and bend on the insides where you brushes are touching is where these lathes help, by straightening and at the same time restoring your commutator to its natural shine lol. I have asked one of the industry pro's advice on this topic and they assure me sandpaper is BAD, so don't use it. As a budget clean goes, I used to use a quality white pencil eraser and clean the commutator and then using the back of a hobby knife, score the lines back in and clean out the carbon deposits. Oil carefully bushes/bearings with only a drop and try not to get any near the brush housing. You can clean your brushes if they are of decent length still with white printer paper by scoring them in a straight line in one direction, folding the paper so it goes to the natural shape of the brush. Its very easy to damage brushes, so be careful. Also something thats been missed here is magnetism, that is no motor magnet is going to last forever, but you can get your magnets re-zapped.. FYI I still run a 16T kyosho modified from 1989 and its still ok in retro buggy racing. Magnets still ok in that one. Commuator still nice, but lathed down a fair bit. So if there's money in your kitty for the hobby, I would recommend a comm lathe, it's certainly a fun and rewarding part of the hobby rebuilding a motor to almost new.
Also don't forget to run in your newly restored motor...I use a 1s pack for this, and say 10-20 minutes is normally enough to seat in some brushes for crawling purposes. Also drive the new motor gently for the first couple of runs, it will greatly help everything set in properly.
