I failed to specify just how little oil I use. About a teaspoon for 1000 chips I'd say..
I can see how my post might be misleading.
If you received chips from
eBay that oily, even after dawn wash, I'd say someone was not using the correct USP Mineral Oil. Tough to say. I've been able to wipe dry just about any oiled chip I've worked on. With a dry microfiber, I can definitely get it off. I don't oil faces of any chips mind you. However, I'm still a newbie and I've only worked with USP mineral oil.
Perhaps I should say, use at your own risk. I suppose there is inherent risk of some sort anytime we try to alter or improve a product.
