Visconti Divina Metropolitan Question

[fpdr]

I just received my Divina Metropolitan. Upon inking it up, I noticed there's ink under the celluloid body of the section. Here are some pics - https://imgur.com/a/hpoym.


Anyone know if this is expected? How do I clean it out?

Same thing happened on my first inking of the Limited Edition Wallstreet (also grey) . Ink got in the little gap between the actual stacked celluloid layer and the inner layer. I managed to clean it a bit with a bleach solution, but the slightly oily properties made it impossible to get it thoroughly cleaned.
After that, I sealed the outer margin with a bit of silicone grease. But some ink is still there, barely noticeable but certainly annoying.
