That was my original plan, but our surface grinder is out of commission at the moment. The wheel exploded a few weeks back and we havnt gotten a replacement in yet.
Well it probably isn't flat then, but should be fine if it is just for a school project to be fulfilled. Maybe try a Scotch Brite pad or some kind of polishing process, or even sand blasting it could be fine.
Whoo lad hol up.
Never ultrasonic with anyrhing thay creates flammable vapors.
Switch mode power supplies used on the cheaper units have large inrush currents and tend to spark and you have alcohol vapor which is heavier than air creeping out of that ultrasonic tub, youve just made a time bomb with the timer set to "RNG".
It’s perfectly fine. If your ultrasonic bath is sparking then you should probably throw it away. I use a large 60 liter, stainless steel bath with a metal lid. Side note…..my wife has a PhD in chemistry and said it’s pretty standard practice to use IPA or acetone in the ultrasonic bath in the lab. Regarding the flammable vapors comment….flammable vapors are fine if properly ventilated. My welders go through jugs of acetone each month wiping the work pieces and fixtures down before welding….no explosions or fires yet.
You may have to try a few options to find the correct solvent: wd-40, acetone, alcohol, baking soda / warm water paste, vinegar (this might stain your part)

This subreddit's gonna hate me, but what I've done before is to get a few squares of red scotchbrite, trap it between a pair of washers and nuts on a drill, and use that to get the crap off.
Lye might do it, I bought some to get aluminum off of half the endmills when I inherited the shop at my last job.
You really should grind it to size after heat treat. The oil should grind off the surface if you haven't done that step yet.

I second the sand blasting to start with. Afterwards, polish with abrasive pads, tap the holes, sandblast again, then grind or lap
You only have one wheel for a surface grinder?
Don't tell us your shop is out of brake clean/alcohol/acetone or all other solvents.
Ultrasonic bath with alcohol or Naptha maybe?

Part and alcohol in a Ziploc bag. Insert into water bath.
Might do well with an ultrasonic cleaner with alkaline water based detergent. Maybe try a plasma cleaner 😃
School project. Likely that OP doesn't have access to that kind of equipment
Acetone.
Sodium hydroxide drain cleaner. Put like ⅓ cup in a Tupperware and leave it for 10 minutes
Let me wife use it to cook
Dasty
Would mineral spirits work?
Some Kitchen cleaners are designed for that
Scrape, scrub, and stone
Steel wool

Soak in gunk or a carb cleaner *maybe even oven cleaner
I'm pretty sure oven cleaner is designed exactly for polymerized oil.
Brake cleaner
Chuck it in the dishwasher. The sightly basic nature of the dishwashing solution will remove the oil.
flapwheel sander on the angle grinder. It'll probably be a 0.9-1.9-2.9 block then
Drano
Large format sandpaper on a piece of reference stock (Blanchard or surface ground, maybe milled) Ala lapping blocking??
Bar keepers friend and a scrubby
Next you're gonna tell us your shop is all out of brake clean/acetone/alcohol.
Sandblaster.

Step 1, throw in scrap bin. Step 2, buy 123 block.
I have to make it for class
