I have access to a dry compressed-air line, dish soap, cotton buds, Isopropyl alcohol, acetone, silicone grease, soldering/de-soldering tools, etc, but don't want to risk making the problem worse without asking for advice first.<br><br>Thanks in advance for any advice,<br><br>-Richie,<br>________________________________________________________<br>This is the Synth-diy mailing list<br>Submit email to: Synth-diy@synth-diy.org<br>View archive at: https://synth-diy.org/pipermail/synth-diy/<br>Check your settings at: https://synth-diy.org/mailman/listinfo/synth-diy<br>Selling or trading?
