Hey Bill Degnan. and All; I will offer my $ 0.02 for what it's worth. Why not try the "sandpaper" trick. Before you all look at me like I used a "stupid rock" to beat my head with, consider the following, with a little latitude. This technique has worked for me with little to no invasive infrastructure intrusion. History... I have a Radio Shack Realistic universal TV remote I bought in the 80's, and over the course of it's life, I have had to open it up and service the keypad carbon pads about 3 times, when the keys don't work. I first cleaned with Isopropyl, but initially found that it did not cure the keypad failure when reassembled. Using regular 10# stock printer paper, (like "sandpaper", yeah now you're getting it) with medium pressure, I polished the carbon pads. This seems to remove a micro oxide crust (I call it) from the carbon crosspoints, thereby allowing contact when the rubber carbon pad key is depressed. I DO NOT recommend using a pencil eraser. Way too abrasive! The remote operates the widescreen 1080 DP TV to this day, every night, with no issues. Hopefully you are not laughing too hard!

I never heard anyone putting colloidal silver on a pet keyboard before.

I used the 91% with qtip on both. I could try the eraser why not...but my method should have worked
