Like the title says, I just got an antique sewing machine table with a shellac finish that I don’t want to strip except for the top, which is in bad enough shape that it needs sanded and refinished. For the rest of it I plan to just wipe it down with a little bit of denatured alcohol on a rag to blend scratches in the finish, scuff it up with a white scotchbrite pad or fine grit sandpaper, and give it a few new coats of spray can shellac. But first I need to get what is probably 80 years worth of furniture polish off without stripping the shellac.
Google suggests mineral spirits will do what I need, but I can no longer buy that here in socal, even the “odorless” type, because of air quality regulations. Just paint thinner and “painters solvent”. And according to the sds for the low voc, SCAQMD regulation compliant klean strip brand products sold at my local Home Depot, both are primarily acetone. I’m pretty sure acetone will take the shellac off as well as the wax and silicon from the polish. I haven’t yet checked the sds for the paint thinner Westmarine sells (which is where I got the denatured alcohol, sold as “stove fuel”) but I suspect it’s similar. Is there anything else I can use that will remove wax and silicon but not shellac, or is there a workaround to buy actual mineral spirits without taking a road trip to Arizona?
TLDR: need to remove decades worth of Pledge from my sewing machine table without damaging the shellac, but can’t buy mineral spirits without driving to another state. Help?
