Cleaning a tritium marker

[highoeyazmuhudee]

anyone have any experience with cleaning the tritium markers on their dials? i received a NOS dial and two of the markers have a dark smudge on them, it kind of looks like a pencil mark. im pretty sure its not due to age of the tritium. what would be the best way to clean it? im not sure what dissolves tritium or would cause it to break down or crumble. i have optical cleaner for lenses that contains no alcohol which ive used on glossy dials and super lume markers without incident.

You mentioned the optical cleaner for lenses. Is this the 'brush & pad" style? If so, I would start there.

While no expert, have you may also want to try gently rubbing the spot with a little Rodico on a toothpick or pegwood.

As a last resort, you might step up to a scratch brush, toothpick end, dental pick, and try and 'erase' the mark. Worst case, you will chip away a little Tritium leaving an aged patina... YMMV.
