How to remove stain / tarnish from Empire 698 deck.
I say stain / tarnish because I don’t know exactly what it is.
It seems deep into the metal.
I don’t want to use the wrong product in fear of ruining the finish.
I tried Weiman wipes...nada.
:?

Alex,
Those Empire bases and headshell etc were made with pot metal, an alloy of whatever scrap metal
Was available at the time of production (aluminium, tin, zinc, lead etc. etc)
It is very difficult to remove that oxidation without altering (destroying) the top layer of patina
On the surface. I have had some measure of success with simple green applied with the softest of
Scotch brite pads and an old toothbrush .try an area under the belt cover ....before you go to town on the highly visible areas.
Good luck

It will require a lot of elbow grease to get it out. The steel wool grade#0000 might work, but I haven't tried it.

Be careful using steel wool. If your turntable plate is an alloy-based material you will embed small amounts of iron in the surface of the deck....mix iron and aluminum and you will get a galvanic reaction and corrosion. It will look much worse very quickly.

First determine if the marks are dirt on the surface or if they are corrosion. If dirt, some work with a toothbrush as previously recommended may be all you need. If this is corrosion, move to step 2.

Step 2: you need to determine whether the metal has a coating on it...like a clear coat. Any abrasion will remove this coating and make a mess. If you have a clear coat, you are going to have a difficult time removing the marks.

I would try a non-abrasive approach first. That way you are not altering the surface striations (the patterned "scratches" on the surface). Try a universal-deoxidant (such as TarnX) on a small area. Apply the deoxidant on a clean paper towel....apply a uniform coat over the surface, leave about 30 seconds, then remove with paper towels soaked in clean water. Dry. See if the corrosion has diminished. If better but not perfect, repeat above.

Anything that scratches the surface MUST be applied uniformly across the whole surface...if not, you will leave an area that will show a non-homogeneous surface. In other the rub marks will show.

Also, be careful (if you use abrasives) that you do not remove the labeling that has been applied to the surface.

Happich Solvol autosol is also a reasonable surface corrosion polish...it does have a little bit of abrasive on it and again it must be applied and buffed uniformly over the surface. Or apply it ONLY to the damaged area and rub only those spots.

Good luck.

Tom

Thanks for the info guys. I will see what works and report back.
I am almost positive it is in fact corrosion and not dirt.
