A little goes a long way but my experience is that it works better if the oil is allowed to soak in and the chip is allowed to breathe for a bit before being put back in the rack. It takes a little longer, but I am usually in no rush.I think you’re adding too much if they need to sit out that long.
My first attempt, I had them out for a day and realized that was too much oil.
Since then, I quick edge wipe a barrel, lightly hit the faces around the inlay to spread whatever oil dripped over the sides into the face, and then put in the rack. I then check back in a month, pull the barrels from the rack and wipe up any excess that dripped down- usually nothing.
The lighter piled chips looked better than the first job I did. Less is more.
Also have found resting on layer of paper towels over reg towels works well too.
