I just found a 12-s-266 at a thrift store. This thing is just beautiful under the grime and old lacquer.

I have striped 80-90% of the old finish off ( it was just too beat up) and have run into this round maybe "water stain" that i cant get rid of with the lacquer/acetone mix i am using to strip this. (see pics)

Any ideas on what to use to try and get rid of this stain?

Also in the pics i am missing a veneer chip right in the front? Maple? Where to get a small piece? or repair...?

Any ideas appreciated.

Thanks

Bill

Wow! That is a beautiful cabinet. I don't think I've seen so much burl walnut on a radio! Weird how the entire radio is burled, except for the top. Anyway, I really don't know what to tell you about that stain. But it's a Doozy! -- Good luck. Have you considered using wood bleach and/or sanding?

Once in a while it's good to buy a junk radio with peeling veneer and save the veneer when you scrap it out...It's a free source of period correct veneer.

I have had some tops with a water stain like that , and I used ''oxalic acid''
It comes in a power and you mix it with water as a paste
Then put it on the stained area and rub it in with a stiff brush,leaving it on a few minutes.

It will get the wood wet, and get into the pores.
Then rinse it off with water, and dry the area.

You might have to do this a couple of times but with the stain you have it should not take too much
effort. Follow this link

it does work

I agree with the oxalic acid also sold as wood bleach. Do not allow the wood to remain wet as that is the surest way to delaminate wood. Make sure the water stain did not cause any delamination.

The front center is Carpathian elm. The sides are butt walnut (aka stump walnut). The top is quartersawn walnut.

Thank you for the wood species.

I had some oxalic acid as i have done this before with a cedar ceiling. I got most of the stain but there is still
a small ring...seems no matter how much i do now no change. I have sanded before, in between and after but fear i
am getting close to going through the veneer. i also tried hydrogen peroxide. Any other ideas...trying to keep the top
more translucent like the sides.

Thanks

Bill

You may not get ''ALL'' of the dark ring from the top of the cabinet, but most people put a dollie on top of the cabinet with a statue or something similar. You can only do so much sometimes. Lets see a photo of what you have done.

I had not scrubbed the stain, so i did. it seems to have taken all of the stain out but now maybe a little too light.
I went over the rest of the top with the oxalic water solution to remove the "tides" ( i read this and it describes the additional water stain you get on the edges after applying the solution - a full wet down removes that).

I may have to add some color back now. lol I wonder if the lighter color is that i removed more grain filler?

I suspect it won't look so bad once you apply a stain and grain filler. These will greatly diminish the contrast.
