Rape seed oil, (Canola), will go rancid over time, but if you wiped it up quickly and inundate the surface with mineral oil, then use your Watco finish it should be OK.

What will happen is that the mineral oil should mix with the Canola and dilute it to the point that it’s a non issue.

If not, you can use the old acetone trick to draw the oil out, but with red oak it will probably go on through to the bottom.
