As I posted in the Recent  Acquisitions Thread, I've just picked up a 1951 Olympia SM2. On this particular typewriter is "decal" (it's actually painted directly on the typewriter) with the name and address of the company that sold the typewriter (Sare, Hyrons & Co.). You can see it in the picture below:

In doing some preliminary cleaning of the typewriter, I took a Q-Tip, dipped it in some water with a bit of soap mixed in, and tested it on the painted distributor marking. Blue paint immediately started coming up, so I stopped right away. So I guess my question is, if such a simple cleaning mixture brings up paint, is it possible to clean this area at all?

Alternatively, I suppose I could consider removing the marking altogether (it does clash with the colour of the actual typewriter, in my opinion). Of course, I would then be risking leaving a residual discolouring where the label used to be. I would be interested in knowing whether others generally keep these sorts of decals and markings.
