Fogged glass on VDO guages in cockpit.

hynesite

1970 vert. Tried using a hair dryer to get the moisture out, but didn't work. Are these glass (or plastic) pieces able to come off so that one can clean the inside of it? Also, is there a seal or something that can be replaced to keep moisture out of these things?

As always, thanks!

I had the same problem with a fuel guage. Remove the guage from the dash. You'll see that the ring is ever so slightly bent over the body. Use a very small screwdriver to very slightly pry the edge every 1/2 inch or so.
Use equal pressure both hands to pop the ring off. Be careful. The ring is very thin anodized aluminum and will easily scratch and bend.There is no seal and I forget if the lense is plastic or glass.

If you take the light bulb out of the rear you will open it up enough to allow the condensation to escape. There is no need to pull it all apart, unless the inside of the glass is filthy.

Usually what you will find is a dirty film has collected on the inside of the glass from years of pollutants combined with condensation. As d4g4m suggested carefully remove the rings then clean and polish the glass.

Update--Also be careful if you have a comparable VDO clock for 1970. The face on this one is not glass but plastic. (Speedo and Fuel are glass on these types) Tried to remove the ring, but because of not paying attention with that little nob thing in the center of the clock, I caused a small hairline crack in the plastic. Also, because this plastic is close to 40 years old, obviously, windex will not clean it. The haze will not go away conventionally.

i worked at a restoration shop where i would restore some guages of the ccars that we did, we liked to use WD40 on a swab to clean the face, test it first as some faces will rub off with this oil, for the glass we would polish with Mothers mag and aluminum polish on a 0000 steel wool.
