After an exhaustive search here...I could not find the answer.
I just bought a Vacuum Chamber and Cactus Juice to stabilize rocks and rock slabs.
Question:
After cutting a Rock into a smaller piece…and/or a slab, using mineral oil in my saw…does the mineral oil, now soaked into the piece affect the resin that would be vacuumed into the rock/slab?
If yes...would appreciate recommendations on how to extract the mineral oil.

Always put your slabs in kitty litter for a few days after you slab them. Helps suck the oil out and return them to natural color quicker.

After kitty litter, a soak in a good degreaser, and a good rinse, the best way to remove any remaining residue is heat, but the flash point for the oil, usually about 300F, may also change the material color. In that case maybe a soak in acetone?

Welcome to the forum!
Definitely use the kitty litter and degreaser, but also make sure the slab is DRY.

I've not stabilized yet but I've read to soak in water with Dawn dish soap for a few days.

I always try to stabilize the rock before sawing to avoid the issue entirely. However, I sometimes wonder if that limits how far in the resin goes when in the vacuum chamber.

go to thrift store get you a cheap used toaster oven bake off your rock at 250 till it stops smoking about a hour or two then let cool do a final wash with soap and water put back in oven at 200 for a hour gets all the water out put in foil the a zip lock bag push out all the air when your ready pull out and put in the juice remember that you leave the vacume pump on till no bubbles come out turn off pump and release vacume let sit and soak for at least 2 days before baking at 220
