MintLP Protractor Issue. Anyone else?

Hello,
I went to use my MintLP Protractor last week to do a re-check of Arm, cause I had dis-mounted the Arm.

Last time I used it, was when I first recieved it, over a good year ago, maybe closer to two years.

What I have noticed with mine, that it was once a frosted transluscent clear overlay over a sheet of glass mirror has now changed.

Now I notice, that clear frosted color of the overlay has turned a dirty brown stained color. Anyone else have this happen?

Whether any other detrimental effects have occured, I am unsure, but this Protractor was always kept wrapped in its protective Plastic Bag, in its Cardboard Shipping Box, it shouldn't have turned a brown color, expecially not for what this protractor cost.

I'm thinking of emailing Yip, and asking why this happened, and what can be done about it? Mark

Yes, Yip made mention that if the Protractor needed cleaning, it should be wiped with Iso Alcohol, nothing else.

And I did with mine once, due to seeing slight scratching of the overlay, caused by the Stylus at the Null Grids.

Dan_Ed,
You are correct sir, that my manual as well says only the use of Lighter Fluid as a cleaner.

Why I thought alcohol, is beyond me, and it seems like so long ago, that I do now forget what I actually used as a cleaner? lol

I do have lighter fluid around here, but if I did mistakenly use Alcohol, that could be the reason why I'm noticing a brownish tint to the Applique Overlay Sheet?

As another poster has mentioned though, the Protactor seems to have no other faults other than this brownish tinge, and certainly doesn't appear to warrant a return all the way back to Hong Kong.

I did email Yip, but haven't heard back from him. In any case, I'll live with mine, and as I've previously mentioned more times than I can count in other threads, it is a really great tool! Mark
