"The SX-101 (early) I was given recently spent a lot of time in a moldy environment. On cleanup, large swatches of the black and white paint on the back of the dial glass came off. The glass is intact, but it's mostly clear now."
Advice: Don't ever clean the dial faces on vintage radios except for a light dusting with a soft tissue or cloth.

I have used just plain water to clean the dials with on the SX-100 series. BUT, be VERY careful. Even just plain water will often "wipe out" the markings on glass dials. Found out the hard way on a Hallicrafters SX-111 and a Collins 75A1! Never use Windex or any of that type of cleaner. Sometimes, and I mean sometimes, adding a small amount of plain dishwashing liquid to the water can help. But, try it on a portion of the dial that won't show if something happens!

If you have a radio with a slightly dirty dial, each time you use it, you'll remind yourself you're operating an old radio.
If you have a radio with a clean dial with smudged and partially ruined dial scales, each time you use it, you'll remind yourself that you were a meathead to have ignored the advice to NEVER clean a scale (meter, dial or otherwise)!!!
Trust me on this one! :-) 73 John

Been there, done that, got the Tee shirt. I once tried "gently" cleaning the S meter scale of a Nice Hammarlund receiver, ended up with a meter with no numbers. And it happened so quickly too, with no warning!

Here is an update on my dial cleaning experience.
First I would like to thank all those who sent their suggestions as to procedure.
The rig I have was stored in Military storage for about 5 years and sat in my friends basement for I don't know how long. It was quite dirty. I at first thought the Dial paint was flaking off but after removing the front panel I realized that it was not flaking just very dirty. Most of the suggestions I had said to use mild soap and water or Windex (blue window cleaner) to do the cleaning. This is what I thought too.
The soap and water and Windex did nothing to really clean the dial. I had bought cotton pads to do the cleaning since I didn't want to get any scratching. These pads got dirty but the black grundge just moved around on the dial. It was almost greasy. Maybe furnace soot? I don't really know what it was but it was black and spotty and looked greasy when water was applied. After playing for a while with the Windex etc. I decided something stronger was needed. I tried "Green Stuff " and water and It did the trick very nicely. I wiped it on let it set for a minute or two and wiped it off. The dial turned white and the numbering remained black. It took about two applications but it now looks great.
One word of warning for those of you who remove the front panel from your SP-600. Check the Audio volume control wiring before putting the panel back . Once the panel is in place the Audio Control wiring is inaccessible and the panel will have to be re-removed. It seems that someone had spliced new wires on the the end of the shielded wiring going to my Audio Control. They had not insulated the splice and it was only about 1/8" from the shield. In removing and replacing the front panel I had of course, moved these wire and they shorted to the shield. I didn't realize this until it was all back together and there was no volume. I wasted an hour removing the panel, fixing the wires and replacing the panel. Live and Learn.
Thanks again to all that helped,
73,
