My depth gauge has fog on the inside glass. After a full day in the sun it is still there. Any way to remove it?

A bare lightbulb burning near the gauge can dry it out. Careful not to melt something.

I've had this issue before - it will dry out....trouble is it will come back when it next rains/gets wet. Not sure of the solution and never tried to fix it - perhaps trying a coat of silicone around the seals after it dries out?

I have this issue on my trim gauge. When I read the manual it says that fog can be normal and will not affect the performance of the gauge.

If the gauge has a back light (night time illumination) turn on the light, the heat from the bulb will clear it in an hour or two hopefully.
