Hi Rehd;

A poster who works in the PC Board industry wrote me when I was having fisheye problems, and pointed out that one drop of oil can ruin 1,000's of feet of PC board material (G-10 fiberglass)with fisheye. You gotta get rid of it.

I would stop & remove it with Easy-Off oven cleaner. Scrub it in, rinse it off after 1/2 hour (use a wet scrub brush & dry with a rag), let dry, sand, and do it again til you can't see the oil stain. It's how I cleaned my mauser rifle stock, it will actually get the stuff out of the wood pores. Be sure to wear vinyl gloves as that stuff is a tad bit caustic. I know a number of people who clean wood in this fashion for subsequent finish.

Best Regards, Spidey
