What is involved in cleaning inside of instrument glass on a Series II E-Type? Speedo and tach are fine, just the smaller gauges are fogged up.

 

Not much to cleaning these, do disconnect the battery as a precaution.

Take photo of how wires/connections are made to the back of the gauge. Rotate the little thumb nuts to loosen the U bracket holding the gauge. Press from the back, pull from the front to bring the gauge out. There are little tabs holding the gauge ring trim. You can rotate that as explained here:

Carefully separate. You can use denatured alcohol to clean the glass, then do a final wipe with a good quality glass spray/cleaner. Reassemble, reinstall, reconnect, test.

 

Thanks Valeria...now I know what Iam doing next weekend.,

 

In theory, not much to it (Valerie makes everything sound easy), but if you have plumber's hands like me, I would suggest you acquire a set of replacement rubber o-rings, aka "instrument lens seal kit". If original, yours will be dry and fragile, and given that the instruments are fogged, it implies they have failed anyway. I think it's about $25, but by snail mail. So while you are waiting, you might consider sanding and painting your bezels. And if your clock doesn't work, we have a member, Michael Eck, who converts the original to electric, and it comes back with new seals looking brand new.
