The cabinets seem to not be finished very well.
The finish may be really thin and worn through.

Here's a simple thing to try...

Go to the hardware store and buy some 0000 steel wool. that's 4 zeros.
The finest available, and only a tiny bit abrasive.
Also buy a bottle of Old English Furniture Oil. Find the one
recommended for light colored wood.

Find a spot that is as you describe, but not too obvious, in case you
don't like the result.


First clean the finsih with some Simple Green or other gentle cleaner,
even a damp cloth with a bit of sudsy water will do. This will take off
any grease that has settled on the wood. Rinse and dry.
Gently rub the wool along the grain in a flat spot to abrade the finish.
Using a soft cloth, apply some Old English. Done.

If it looks good, do some more.

Refinishing is big, messy job.

Or you could just paint them.
