The bottle is a cobalt water bottle. I cut the bottom off and polished it smooth. It has a reproduction Edison squirrel cage bulb.
The wood is some very old recycled timber given to me by my brother in law
Bar Keepers Friend cleanser can remove old coffee stains from ceramic mugs
I have some mugs that are 25 years old. I took it for granted that the coffee stains were permanent. Then I tried scrubbing the bottom with dish soap with no improvement. Next was toothpaste. I hoped the mild abrasive would help. If it can restore headlights I hoped it could restore mugs. Still, no improvement. Finally I tried Bar Keepers Friend. This has a very fine abrasive. It worked well. Here are two pictures taken before and two after cleaning.
I would also have used Bon Ami. I’m not sure I would use Ajax or Comet but please comment if you had success. Finally I would not scour the outside because I think it would remove the decoration.
