dirty instrument panel glass on P15

[bigaadams]

not to my knowledge...careful here as original wires may be brittle insualtion and the oil gauge needs be handled with kid gloves..removing the cluster will be you best bet to clean the unit..while out one can also take advantage of access to the speedo and touch up the color indicators at the same time.

The instrument panel glass is dirty on the inside.  Is there a way to clean it without taking the instrument panel out?
