Yes, any mineral oil will suffice to clean up the vege oil residue. I used white mineral oil- aka baby oil. The combination of vege oil for cleaning and then baby oil worked very well and was pleasant to work with. I matched my MB 300D injectors for spray pattern and pop pressure by changing and honing their internal shims. I did all my pop testing work with vege oil for safety and convenience, then flushed my pop tester, then the injectors with a light mineral oil.
Straight vege oil is a far better and less toxic cleaner than I ever imagined.
