After many years of use my keyboard had gotten so dirty that it was painful to look at.
I started thinking about how I cleaned PCBs after soldering.
I rounded up the back brush from the shower and an old tooth brush. At the kitchen sink I turned the water on hot and put a small amount of dawn dish soap on the back brush. I scrubbed and rinsed the board using the sink sprayer a few times.
Next I used the tooth brush to clean the few remaining dirty spots.
I shook out all the water I could and set it near a heater to dry.
After two hours I tried it and nothing.
Two hours latter and the mum-lock came on when I plugged it in. Good sign.
As you can see it is working. Or maybe you noticed none of the words in this posting use the letter that falls between u and w in it.
I find it odd that only 1 key would fail. More like a row or column in the matrix. Could be it is still on the damp side. Time will tell.
If you see me posting text with THAT letter missing you will understand. On the bright side as letters go if you had to loose one "v" is not too bad.
