Hello. I recently bought a sewing machine in a cabinet with top I
will have to refinish. (The machine is probably from the 1950s). Being
in the middle of a some refinishing, I decided to test the finish to
determine what I am working with. I found a "good" spot and dabbed
some lacquer finish. Nothing happened. So I dabbed some denatured
alcohol in another spot. Gummed up then turned really white. Thinking
that maybe I had accidently put it on the same spot or on a spot that
had some moisture. I did it again. Same result. Then this morning,
just to be sure, I tried in another spot.
I have done web searches and can find plenty on white water rings, but
nothing on denatured alcohol causing the suface to go white.
Any ideas what could be up>
www.homesteadfinishing.com has several forums and Jeff is very
diligent in answering questions. One forum, maybe Repair & ?, might
help your quest. There are other forums for repair out there so if
you don't get it resolved please repost advising what you did and

Was that lacquer "finish" or lacquer thinner? On the alcohol, how long did it
take to have an effect? The way you said it, sorta implied an immediate
response from just a "dab". A typical shellac finish will take a few minutes
to respond to alcohol, and will not usually turn white. However, I've seen
that happen with shellac over varnish or other coatings that are impervious to
alcohol. It apparently breaks the mechanical bond and forms an air layer under
the shellac, which then appears white.

Hmmm...maybe shellac and oil mixture. Check with a pencil if the surface is
hard or has a little give. If hard and you're just concerned with the surface,
may be able to coat with shellac, first coat very-very light to seal, then
heavier, followed by whatever. If soft or wood surface needs repair, you'll
need to strip.
I now seem to remember seeing this many years ago on something old, but I've
aged as much since then, so the memory's failing.
As was previously mentioned, suggest you run this through
www.homesteadfinishing.com . Jeff may recognize something here. If he does,
let us know what happened.

Good ideas. I have a mixture of shellac, oil and denatured alcohol
that I might try. I suppose that if it doesn't work I can always
I will also try the list you suggested.
THank yo9u so mcuh for your ideas
Hi. I am going on vacation tomorrow pending weather, but hope to work
on this project when I get home. If there is a follow-up question to
my questions, I won't be able to answer it until then.
I look forward to hearing any advice you guys have. In the past year I
have tried to do some restoring/refinishing and am quickly learning
that good advice save much frustration. I have a number of sewing
machine cabinets that I seem to be aquiring and would like to fix them
up without doing a complete refinish job.
