Even though we use placemats, we have gotten a few spots from food, probably oily food, on our teak dining table over the last month or so. I have scrubbed them with a soft cloth, mild detergent and water, but that only served to lighten the area around the spots. Meanwhile, the spots are still there. I understand that oiling will take care of the lightened areas, but what can I do about the oily spots?

Thanks.
