If that is the same meter that is on a Quietline and if the meter works, the lens is a easy fix. The "fog" is on the outside.

I had a non-working one to test on, so I experimented.

My first try was perfect. I used
1) car polishing compound (not rubbing compound)
2) the black bristle brush that comes with a Dremel kit
3) some gun cleaning patches
4) a 2500 rpm drill (speed is critical, not too fast, not too slow)

The brush is the one that has the bristles pointing away from the tool, not perpendicular to the shaft.

Use the brush and polishing compound first.

Then follow that with the brush driving the gun cleaning patch with compound.

Mine look like new now.

Takes 5 minutes.
