IBM PS/2 P70 Restored!

Yeah it needed a good cleaning. I use windex and paper towels as first line on most of my retro equipment - seems to be the least abrasive. Isopropyl alcohol on more stubborn marks if needed. On these textured surfaces I will also go over them with a Mr. Clean sponge with the lightest possible pressure. Don’t want to rub the texture off but I find the slightest go over with them helps to remove the last little bit of dirt that gets buried. The keyboard as you can see was very dirty so I removed all keys and washed in soap and water. I didn’t disassemble the keyboard since it was working and didn’t want to risk damaging it since it is irreplaceable. It had lotus123 stickers across the top - a little heat and the double sided tape came off nicely. Most stubborn cosmetic thing was this: https://imgur.com/a/bRcUxRf Seems to have been a bracket for a security cable. It was all metal and attached with strong adhesive. I didn’t want to damage the case but it was such an eyesore. What I ended up doing was using my hot air station on the lowest possible head (100C) and high air flow, and went over the edges. The bracket was metal so it absorbed heat which wasn’t great. Certainly didn’t want to melt any plastic. It was just enough though to get a plastic prying tool just between the bracket and the case. Once I did that I dropped a ton of goo-gone down it and let it permeate. I then basically used a second tool to score the adhesive pad on the sides, more goo-gone, small amounts of heat applied to the increasingly exposed adhesive, and just very slowly and patiently worked it off. Eventually came off and didn’t leave any marks. Was worried there would be a discolored spot but you can’t even tell it was there.
