Hi group

I am thinking of buying an old mid 70's sideboard. It's very stylish but
the finish is a little bit tatty. It's a teak veneer.

I was wondering if the veneer could be sanded down with a fine sandpaper,
just to get rid of the top layer of light scratches and marks and then rub
it down with teak oil to finish it off.

Or is sanding down a veneer a no-no?

If it is a no-no, what's the best way to improve the look of the veneer?

I haven't had much luck finding answers with google, so any advice will be
much appreciated.

Regards

J.
