Stripping dye off keyboard
https://audioroundtable.com/forum/index.phpindex.php?t=rview&goto=96313&th=23555#msg_96313
I know I haven't been on here in a while, but that's because I've been busy with my new job. Since the kids are older, I've finally able to go back to full time-employment. I hate to pop on just because I've got an issue, but I'm desperate, and I know you guys know your stuff.]]>Madison2023-01-29T14:12:50-00:00Re: Stripping dye off keyboard

The problem, of course, is to use a solvent that will dissolve the dye without attacking plastic parts or anything that might have been silkscreened or painted on your keyboard.
I generally like to use flux removers and/or alcohols for circuit boards. I use (automotive) brake cleaner on really tough stains, but it will destroy most plastics so that's not an option for you. And really, flux remover will damage some plastic and some silkscreens, as well as PCB markings done in ink, like an ECO level, serial-number or revision number hand-written on a board. Isopropyl alcohol is usually pretty safe, but even that can damage some materials. Still, I'd start there 'cause it's the most "friendly" of the three solvents mentioned in this paragraph.
Using 91% isopropyl alcohol, rub a little on a part of the keyboard that's safe, like behind the faceplate and/or on the edge of the circuit board. Make sure it doesn't damage the part you're trying to clean. If it's safe, start using the alcohol to clean the areas where dye remains.

Just do a bit of research on what solvents are plastic safe, use the Q-Tips for the cracks and crevices, and you should be good to go. ]]>Concorde2023-02-01T17:07:28-00:00Re: Stripping dye off keyboard

Did everyone think I was talking about a computer or laptop keyboard rather than the musical instrument? If so, that's pretty funny because I used the advice from this thread to clean the Korg. There's still some light staining visible, but you have to know where to look in order to really see it. When I first turned it back on, the keyboard had an odor, but that's slowly gone away. What really matters is that it plays okay. It didn't look like the dye got down to the pads, so we probably got off lucky. ]]>Madison2023-02-02T01:01:40-00:00Re: Stripping dye off keyboard

I love old Korg and Moog synthesizers. Especially the early analog units. ARP too. So cool!
And the Fender Rhodes piano too. Classic!
The later digital stuff is great too, especially after sampling became popular. But I have a soft spot for the 1970s and 1980s analog keyboards. The ones where you set the waveform, filters and attack and decay.
As for the cleaners, it's pretty much the same whether it's a computer, typewriter or electric piano or synthesizer. But surely the replacement cost is a difference. If it were an inexpensive item, then I could see where replacement might be the best option. The more rare or expensive it is, the more repair and cleaning makes sense.
