Hi, Guys,
I’ve got a wood finishing question stemming from a kitchen mishap! While rushing about fixing dinner the other night, I dropped a bucket of coconut oil, which went flying all over a raw luan-faced door and raw Doug fir casing. The weather is cooler now, so the oil is back in a solid state. Does anyone have any suggestions on how to dissolve the oil so the wood will regain its unfinished look? Any help will be appreciated.

Paint thinner and cat litter. Repeat and keep repeating. The fir will be OK, but I have doubts about the luan. Lots of little microcracks for the oil to soak into. Soap and water may do a better job of removing the oil, but with the obvious bad side effects. If you can get the surface color even, a wash of shellac may seal it well enough to get a finish on it.
would it make sense to cover all the raw wood with the coconut oil to not have to fuss with matching stain and whatnot? then a washcoat of shellac to isolate the coconut oil and what ever finish you desire?
Something I didn't mention in my initial description of the situation is that it occurred in a house we are renting. It is a cedar kit house, and all the wood throughout--doors, trim walls--is bare. So I have to either remove the oil or replace the door and casing. As much as anything, I look at this as an interesting challenge. Thanks for the help.

Gunsmiths use a mixture of lacquer thinner (or other solvent of your choice) and whiting, which is like crushed chalk. The solvent dissolves the oil in the wood, and the whiting holds onto it, since it's more absorbent than wood. I've used it on a military surplus gunstock, and it really does pull the oil out. It may take several application, and I don't promise that it well ever get enough out so that you can't see the difference.
The only source for whiting that I know of is Brownell's gunsmith supplies in Montezuma, IA, but a Google search might turn up others. Google for Brownell's address, too, I don't have it handy.
White carpenter's chalk. Same thing as whiting. Easier to find but more expensive because of the nice bottle. Baking soda, corn starch, flour, or any fine powder will work about as well.
I second solvent & corn starch. Use paint thinner, lacquer thinner or naphtha. Make sure there are no ignition sources around or you might not have to worry about the stains.
Unc, and spruce,
A good paint store ought to have whiting.
Cheers,
Ray
That's good to know. I wouldn't have thought to look there. What do painters use whiting for?
No paint store I know has whiting anymore. Maybe you have better stores. Back before lead and titanium pigments, you mixed your own paint. Boiled linseed oil and whiting = white paint. Glue and whiting = filler. Whiting plus just enough raw linseed oil = glazing putty.
Uncle Dunc,
Our local Duron Paint store carries it. I guess the painters use it the same way I do, to thicken up putty (not glazing compound) after you have added universal tinting colors to match a wood color. I do that for glazing windows in furniture, but around here, at least, painters also use it to fill nail holes, etc in finished woodwork.
The brand available here is "Rainbow", they also make Plaster of Paris and other products similar to that.
Regards,
Ray
Uncle Dunc and other friends,
I just love this aspect of the digital age. A lot of good ideas here. Thank you all for your help.

If the other solvents don't work you might try acetone. And maybe rub it in with coarse sawdust or wood shavings.Gretchen
While all of the methods outlined will remove most of the oil, none of them is likely to remove enough of the oil to make the stained wood match the raw wood.
Having unfinished wood in a kitchen is foolish, you just happen to be the poor guy who got stung by someone else's poor decision. I'd try to talk the owner into properly finishing the cabinets before more inevitable mishaps really ruin the place. The wood you accidentally stained could easily be blended in when the cabinets were given a proper finish.
If he or she doesn't want to do the job properly, I wouldn't feel that obligated to undo the damage.
