Hi folks….

I finished off two hanging chess boards and after all was said and done, I noticed that I had gotten some of the Deftoil Danish Oil on the plexiglass that holds the chess men.

Does anyone have an idea for getting the Danish Oil off?

Danish oil is a mixture of BLO/varnish and a thinner, probably MS. If it has been a while, the thinner may have dissolved some of the Plexi and the varnish may have a firm grip on it. It will almost certainly have to be mechanical removal, careful scraping maybe with a utility knife blade. If it’s fresh, wiping it off and cleaning with MS may do it. You may wind up having to replace the plexiglass.

I’ll try the MS and hope for the best. Replacing the plexiglass is impossible unfortunately.

Thanks..Don

How big of an area? Try Fred’s razor blade approach first, if its not in a obvious line of sight area, you could try wet sanding it out with 800 grit and working your way up to 2000. Then use a small towel and a buffing system available at some hardware stores. (Novus 3-2-1 system)

Hmmm, neat project, any close ups of the affected areas? Is the varnish a surface imperfection or did it dissolve into the plexiglass a bit?

That’s actually an old project and I haven’t even taken pics of the project yet.

I have a feeling that Plexiglass and Oil have joined, merged into one now. Unfortunately, it was one of those “I’ll clean it up after…..” and never got to it

Did it turn it a milky white color? I’m not a huge finish guy but did the oil dry up and form a hard raised bubble like a dried drip of urethane, or is it more like a greasy amount of oil that won’t wipe up?

Hmmm, hopefully it’s just on the surface. Looking at pics, the plexiglass isn’t something you’re looking directly through like a window, so even a not so perfect repair will be better than the milky white. You could try the novus 3—2-1 stuff without all the wet sanding, nothing to lose there but a bit of time. The #3 has a mild abrasive that might lift the milky spots off if they’re just a surface imperfection.

Well, I dragged out the bottle of MS this morning and a rag and I’m happy to say that I was about 95% successful!

Thanks for the MS tip.

One of the things that can be done to remove minor scratches in plexiglass is to brush it with a propane torch. Don’t panic at the word ‘propane’. When I say brush it I mean to pass the flame across the surface back and forth at about twice per second and a few (4 or 5) inches away. Obviously you should practice on some scrap material first to get the hang of it. I have used this technique several times to ‘clean up’ plexiglass windows.

If the affected area is hard to get at, as in your case, then you may not be able to do it, but it’s a technique worth knowing about for future reference.

Have your say...
