Keith… you are just a man with intense man of action kind of sweat, you could probably turn aluminum Cups. I look forward to seeing the pictures.

My Squatty Cups are now all cloudy and turning that dark penny look, I just rotate the Cups each day and handle them.

I have read about many formulas on the internet, but the use of chemicals scare me. There was one with baking soda that I was tempted to use, but decided against.

Take care,
Bruce

I have experimented with numerous types of home 'recipes' on my set of TF Phoenix Cups over the past month. After many attempts, I have now cleaned them back to their original finish. (Well, actually better than the original finish.)

The baking soda idea seemed to be working but produced very odd looking results... Initially it seemed fine, but after several applications they were very splotchy and odd looking.

Vinegar and amonia applied directly to warm cups wasn't any better. Dark spots and odd pinkish swirls.

Fuming with vinegar only, (Cups suspended above vinegar in an air tight container.) resulted in the deepest blue-green fuzz imaginable. This was rinsed off to reveal a finish that looked as if the cups had survived a fire.

I considered trying Liver of Sulfur or one of the other 'patina restoring' chemicals, but at the end of the day have decided to let them be... if they turn fine, if not, then that's fine too. I handle my cups daily but beyond finger prints and smudges they all look pretty much like new.

Miles - I think your cup looks great. Hopefully mine will get there eventually.

Best,

dc

Thanks DC. I got them to become about similarly brown with regular handling, but then for some reason one of them got a HUGE shiny golden palm print on it. Like my print had washed away all of the patina. It looked horrible to have such a huge difference on just one of the cups.

I got tired of waiting for it to blend back in, so I tried the sulfur.

Like I said, it's hard to get a consistent result with that method, but since the time frame isn't so long, it may be worth trying. However, that picture is not a before/after, it's an after/before.... I ended up polishing them, and now I'm trying the natural handling technique again.

The main thing when you try to get a patina on your cups -- whether you use artificial means or not -- is to clean and degrease the cups thoroughly. Don't just wash them. Use a good liquid detergent, then a good degreaser. Then rinse the degreaser off the cups with distilled or filtered water.

Hi, Bob
It's a normal watch. Doesn't do anything Smile
FYI it's Seiko Arctura

Cheers

I have the opposite problem. Living in Las Vegas with very low humidity, my cups keep their shine for years. That's why I resorted to the artificial "kick start" to get things going.
