So simply put, don't wash it.
On the plus side, it made my personal debate on stock or aftermarket gauges in the cluster pretty simple. If anyone needs the stock Vacuum gauge for this cluster let me know, I didn't clean that one

I also found that out the hard way. I had wetted a Q-tip and was gently cleaning the face of my speedo when the "1" turned into an "i." Ouch! It was one of those moments when you just stare at what you have just done and wonder if it really happened... Anyhow, probably best to gently blow air on the face and wipe with a soft cloth.Low and behold, the ink used to print the face of the gauges is water soluble.
