I have an IR remote that needs cleaning since the buttons require excessive force to operate. I tried alcohol and a toothbrush on the circuit board where the buttons make contact, but it didn't last long, and I had to do it again. The second time, I soaked the rubber keypad in soapy water for a couple days and cleaned it with a toothbrush and also recleaned the board with alcohol. Seems OK at present but a couple keys are still hard to press, and I'm sure I cleaned them. I'm wondering if using some contact cleaner would help?
