tsp dripped on table

salbwilSeptember 25, 2007

Hello,

I posted this in another forum before finding this one. I recently dripped some phosphate free TSP onto my dining room table . The drops took the finish off where they landed !

Is there a cure for this other than a total stripping of the finish as it is veneered?

Thanks,

Did it take the finish off, or just dull it? If the latter, you may be able to buff it out.

Do you know what sort of finish it is?

It ate the finish down to the bare wood. I believe it is varnish. The table is from the 20's. I guess I'l have to sand carefully and poly..............do you think that may work?
And thanks,

Unless it was refinished in someone's garage, it is likely not varnish, but more likely shellac or lacquer. Both are more repairable than varnish. I will sometimes use a TSP solution to clean shellac brushes. A strong base, it neutralizes acidic shellac very quickly.

the article below will give you a good idea of how to repair shellac damage

Thanks,
I will test first with denatured alcohol, then with lacquer thinner and see what happens. Appreciate the help !
