Degreaser for cooking oils

[anwat]

I picked up some very nice aluminum storage cans that were used to ship sunflower oil blends used for cooking and packaging. I'm having a hard time cleaning out the last of the oil, though. Seems the best thing so far is Castrol Superclean. Anyone have any suggestions on something that might work better? I've got a lot of Xylene, or maybe acetone? I'll post a label to show what was in the cans.

Maybe Purple Power. I used to get it at Napa. At work we have Formula 10.

I am still trying to find something that will clean this.
I used that oil in my diesel Mercedes and my tank inside is the same.
I was able to remove most of it with regular gasoline but not all of it, you can still see a light film.

Xylene is some amazing stuff !
I’d try gasoline ( like iceman mentioned ) for the bulk of the work and finish it up with the Zylene.
Word of caution that Zylene is some seriously bad stuff - don’t go soak’n your hands in it !

Adjustment: I just realized that I was thinking of another solvent when first responding to this and it was Toluene - neither one is good for you but they clean greasy parts better than anything else.

PurplePower is probably about the same as the Superclean. Shortly after posting, I tried gasoline, and as mentioned, it seems to get most of it. I will let the cans sit in the sun and warm up pretty good and then hit them with Xylene and see where we get. I'd like to use these for storing acetone, xylene and IPA in, so they need to be pretty clean.. Maybe steam cleaning would help...thanks for the suggestions!

Steam should remove what's left after the gasoline.
I couldn't do it inside the tank but in your case it's very feasible

Seed oils are often created using solvents, like Hexane. Alternatives include Isopropanol and Ethanol, so you might try your luck with denatured alcohol or rubbing alcohol.

Taking that into account, I decided to try Flex fuel ...E85 works pretty good, a couple of rinse outs with that, then hot water and Superclean or whatever purple degreaser, and it's pretty much gone. Going to try a brush on the drill for the last little bit, while pumping steam in there, then rinse and see if I have a film or not. The hot water helps a lot.
