How to clean button contacts of IR remote control?

After what you did it doesn't sound like it's a contact problem. It sounds like the membrane has lost elasticity or just fatigued at the flex point.

I've had moderate success with the dish detergent/tooth brush cure.

I've read where someone claims a light sanding with fine grit sandpaper on the black buttons that contact the board will work. I may try that if the detergent trick fails.

You can glue aluminum foil on the buttons or make the buttons black with a soft pencil. I tested a number of different pencils for resistance and used the one with the lowest resistance.

Before you try *ANY* of the other suggestions, try removing the button mat and wiping each offending button contact across a sheet of copier paper so it leaves a mark. This exposes a fresh surface while removing the absolute minimum amount of contact material and usually is effective. It is far less destructive than other suggestions, and can be repeated i the improvement is not sufficient or if the trouble recurrs.

You can also get two-part conductive goop specifically for renewing the button faces.

Yes, that worked well. I wiped the bad contacts with copier paper which left mild black streaks on the paper. The power button was the worst and is working well now. Thanks for the tip.
