I tried everything.
Soap and water
Brillo pads without soap
Fine sand paper
And in a last-ditch effort 1 tablespoon vegetable oil mixed with 1 tablespoon baking soda from One Good Thing’s site.
What it did was loosen the grime enough to scrub it off with the Brillo pad. The Brillo pad with soap. It still took quite a bit of scrubbing.
I decided to let a couple of cabinets sit overnight with the concoction.
It didn’t make any difference.
Hint: Do this in the morning light when you can see best.
Of course, I scrubbed so hard I also took off some of the varnish.😦
What have you used? What worked and what didn’t?
