Cleaning silver marks off white coffee mugs etc.

Thanks for all the tips, guys. I normally never stir coffee--when using a bit of cream I add it first, then let the Keurig brew into it--but when a wisdom tooth was removed this summer, I had to rinse with warm salt water several times a day for a week, so stirring-to-dissolve was involved. Consequently, several of my Buffalo china-style diner mugs have exactly the grey marks in the bottom described above.

Had hoped my brief dalliance Bubble Bandit dishwasher detergent would take care of them, but no. It did remove coffee stains from the interior of the mugs, though.

It's about time I actually take care of the issue rather than gazing into a mug every morning thinking, "Gee, that's ugly." (Aside: Having spent 40 years of my life scheduled down to the minute, I've adopted an exceedingly laissez faire attitude in retirement that some might more accurately call rudderless drifting, lol.)

I don't have-and should pick up--Bar Keeper's Friend; but I do have baking soda and a couple of those Magic Eraser sponges.

Checkrate/Likes I don't know how, but I've suddenly discovered a number of my white coffee mugs have picked up random "silver" (actually grey) markings on the interior and bottom surfaces. Clearly from stainless steel spoons. Any pointers on removing them?

Checkrate/Likes 1 I've read here that using silver polish will remove marks on dishware, so I see no reason why it wouldn't work on mugs. Coffee mugs, that is.

Checkrate/Likes Barkeepers Friend or Baking Soda rubbed on the marks will get rid of them. We used to have a set of dishes that always got these marks on them and BKF always got the off and didn’t scratch the surface of the dishes. Eddie

Checkrate/Likes 1 and if that doesn't work, try a Magic Eraser... they're little miracles in a sponge.

Checkrate/Likes *BKF* Another vote for BKF. I use this to remove these kinds of scratches from plates and other things too. It works very well.

Checkrate/Likes *Simple ....* add hot water and a half teaspoon of barkeepers friend to the mug and let set overnight. Had to do this to some bowls and mugs in the past and it works marvelously.
