Bronze watch cleaning and removing patina

My bronze C60 was purchased new from CW. It arrived with some patina (a bit uneven) already on it and I wanted to start out clean. So it was time for a quick bath and light scrubbing to start out with a shiny clean bronze C60.

I used 1 teaspoon of citric acid and 1 teaspoon of sodium bicarbonate as instructed by CW. The patina came off pretty quickly and probably didn’t really have to use a toothbrush at all. But it may depend on how much patina there is on the watch.

It looks like new again after the bath and I am looking forward to see the patina develop again.

Comments on the post in the CW Aficionados group on Facebook:

The watch as it arrived.

Citric acid can be found in the canning section at Walmart and I am sure many other stores as well. Sodium bicarbonate is baking powder and can be found in, you guessed it, the baking aisle. Also available from Amazon and other online stores.

Mix the ingredients in a bowl, put the watch on top and add water so the watch is complete submerged.

Patina was very light to begin with so I only let it soak for about 8 minutes. I used a new soft toothbrush to finish up and it came out like a brand new watch.

Instruction video from CW:

After 3.5 weeks with occasional wear under neutral lighting. Occasional swim in fresh water lakes. The strap buckle also gets the same patina as the watch.

Cleaning of the C60 Bronze Ombre. it is such a satisfying process to see the bubbles and how the watch restores to new condition.
