Clear Tachometer Face Cover Now Foggy

[landonshaw]

I have gotten ambitious and am trying to fix all those things on the boat that are not broke. Doing this, I sprayed the contacts on the back of my tachometer with an electrical contact cleaner and found that after doing so, the spray became liquid on the clear face. Not being able to clean it I left it for a future day.

It evaporated but seems to have lightly etched the clear plastic face and I am unable to read the gauge. Taking the face off I have washed it with rubbing alcoholic and it still remained foggy. It doesn’t seem to be an oil film. When a clear liquid is on the face, you are able to clearly see through the face cover.

Does anyone have a suggestion? Possible buffing the face would fix the situation, but what type of tool would I use? Also maybe a thin layer of a liquid that would harden, again what type of liquid might work?

These are two thoughts I have had but am afraid to make the matter worse so am trying to find a number of fixes before I attempt one.

Thanks,
Aloisius

Thanks, I went with the web sit and used a small buffing pad on a drummel tool. It worked great. Now the problem is that it is clearer than the other gauges...I will leave them alone, I have enough other things that are broke that need fixed.

I may try the brasso though, that sounds interesting.
