= How to fix remote buttons for good =

[Username1]

Ok, so on one of our Insignia DTV remotes I have to clean the buttons almost
daily so I can use it for the day..... Our cordless needs cleaning 2X a year.
I take them apart clean both the rubber button under side, and the pc board
with alcohol, or window cleaner. Both get some crap off, the paper towel has
black dirt on it when I'm done. I found a few links online they say its silicone
oil leeching out of the pc board..... and the pictures look like it does on my
first cleaning, there is oily stuff on it.... But not any more, now it seems they
need a cleaning just to use for a while..... The sites online say to use acetone
but I have seen that stuff kinda eat away at some plastics, and not sure if I
should chance it.....

Our telephone also needs the cleaning, same method, alcohol, but the cleaning
lasts much linger. 2X a year.... Everything looks very similar......

Is it really silicone leeching ? Will acetone hurt it...? Any of you have experience
with this problem....? What do you guys use....?

Both items have been in daily use since about 2009.....
