I set my cutting oil I use for drilling metal on an oak slab I've been working on for a minimal (only parts of it will receive resin) river dining table.
I turn around and one of my shop cats knocked it over and it seeped into the surface.
I tried sanding the bejesus out of it after wet vacuuming it and it looked normal. I then put the vac back on it and it pulled more to the surface. So I sanded again. Vac again. On and on and it's barely making a dent.
It's air dried Texas oak, so it's super hard. Hopefully this fact has kept the oil from going too far in but if it doesn't come out I'm considering doing some gouging and pouring my epoxy resin into this spot at well. Any ideas or tips would be appreciated.
Photo's of the piece would be good.
Not sure there is anything to remove it. but somehow work it into the project. Here is where a photo would help my comment.
Not knowing the shape or size of stain.
Oak is an open grain wood, so it may have soaked into the grain deep.
With that, depending on the shape of the stain. A variety of inlay shapes are possible.
Both epoxy, wood, and metal inlays, and or a combination of all. I use powdered metals in inlays. Brass, and copper.
you mention River table, so I am sure you know of Mica powders and such that work well with epoxy.
Make the stain area an embellishment. A patch will always look like a patch. But if you make it part of the river scene. I will work out well.
good luck.
Try brake cleaner from an auto store . It is a great solvent. It evaporates quickly, so it may take a few applications. Try it on a scrap first to see if it leaves a mark or changes the color of the wood.
That is a real problem. Almost anything you do will probably just thin the cutting oil and make it penetrate deeper but if you want to use the slab I think I would first at least try to remove the surface cutting oil with a solvent and the spray brake cleaner would be a good start. At least it won't add to the problem. Next you will probably have to apply a stain or oil (wood oil like tung, BLO, Danish) to the whole slab and hope it blends everything.
As an old painter, a solvent can only make a spill bigger. Take a large paint spill and pour thinner on it, it just gets bigger. My point is that the brake cleaner could mean driving the thinned oil deeper. It's a crap shoot at this point and although I greatly appreciate the great advise and experience of LJ community, this may be like "what's the best sharpening method". The biggest difference is we all sharpen but cutting oil removal on a old oak slab is unknown territory for me.
But you clean up the spill first then use the thinner for final clean up. The thinner only makes it bigger if you don't clean up first. Same with the oak, the spill is wiped off, now it is just clean up the remains.
Oh, that's a simple thing to fix. You're gonna have to use a oil finish.
Seriously, have ya had any luck with this because I've sure never been able to remove a oil stain.
