I have an old kitchen cabinet (from 100 year-old house) that was used in a garage as a workbench. I am restoring it to use in a cottage kitchen. I have stripped all finish off down to the original wood. From the workbench days, motor oil must have seeped into the wood counter top. The oil continues to weep out onto the unfinished work surface. Is there a cleaner or chemical that I can use to draw the oil out or perhaps seal it into the wood?
