I got one of the 275g ones that were previously used for avocado oil. It was pressured washed but still smells heavily of the oil. I did not reach in to touch the walls to see there's still any oil residue.
What do I need to do to make sure it's safe to use to hold my rodi water in preparation of making saltwater for my 180g upgrade?
