Rust (?) near the eyepiece of my Kiev III

[Sid836]

There has been some hard white-blue or white-green thing accumulated around the rangefinder eyepiece of my Kiev III. I have tried removing it by scrapping it with a bamboo stick, but without any luck. It has been more like eating up the bamboo stick that removing that thing.
Is there a way to clean it up? Is it going to eat up a lot more in the near future?
Can't tell how much I hate it on my lady!

If you can get some of this it would be worth trying. www.nevr-dull.com Also check this site in german where I first saw the recommendation of the product.

I will go out buy a can of it tomorrow. Thank god I am on vacation tomorrow and I will spend it on caring for my fav Kiev.

Thank you!

--- Update ---

It did a great job! It has removed almost all of it and it made it look nice and shinny! I will try it to mo other rangefinders too.
