Lazser cutting foam residual oil problem

[Pahighlander]

I cut the holes for my shells in a pelican case. looks good but now I got oily substance in the holes. Any ideas on how to remove that

I would think you could wash open celled foam in the sink, squeeze it out, and let it dry.

not a fan of open cell foam that can hold moisture for gun stuff.
no clue on what that "oil" is, but i recommend coating it with plasti-dip or something so it isn't a sponge.

Looks like it's in an airtight Pelican style case. If stored correctly (like that) open cell isn't an issue unless it sits for ten years...

It is an air tight Pelican case V200. I needed something long enough to hold my cheytac shells. the Dawn worked great, that was an awesome idea.
Thanks again

Or, entirely hypothetically, someone leaves a case of fitted foam, with a thermal and tanks in it open in the rain and doesn't tell you so you only notice when doing post-field PMCS two weeks later.

Hypothetically.

Sounds like

It's always a good idea to put some desiccant packs (or the end of a pantyhose filled with rice) in any sealed case that has things in it that can oxidize. Same reason I have two golden rods and industrial desiccant in my safe.

Make sure that foam is bone dry before using it.
