Drill a small hole in the back of the speedo close as you can to the face of it.
Make sure the hole is at the bottom when reinstalled.
Take a syringe and fill it with rubbing alcohol and insert it in the speedo with the face down.Swish it around then drain.
You may have to do it a couple times to get the film off then leave it at room temp overnight to evaporate the excess alcohol and reinstall in the morning.
Don't cover the small hole you drilled it will keep the moisture from re-forming.
I have done this on a couple bikes,including my own and it works well.
