    Removing patina from a bronze watch easily?

    Saw this elsewhere - looks staggeringly effective - if a trifle unorthodox. Simply immerse in 7up soft drink....

    During


    After!

    Lemon juice and baking soda also works a treat - mixed together into a light paste, applied with an old toothbrush, left for about five minutes and then washed off.

    Yep, lemon juice and baking soda is generally the preferred method.

    Not sure I'd want to be putting anything on the bezel Insert like in the picture though

    Isn't the attraction of a bronze case that it gains patina over time?
    F.T.F.A.

    Good old Brasso does the job on my Magrette, it comes up a treat. The fumes are terrible though, you really don't want to breathe them in..

    Cheers,

    I’d say it is; however, with mine, I ended up with uneven patina (I think from getting caught in the rain a few times but cannot be certain); therefore, I wanted to reset the patina. Using the method I mentioned above, I brought my Zenith back to no patina and 12 months on, I am back to where it was but with a nice, even, finish.

    So giving them a clean is good for the above or if you just fancy having the watch look quite different, just for a change.

    Some like to make them shiny again for resale - I don’t own a bronze now but just thought the technique was intriguing.

    I'd be gutted if I lost all that hard earned patina from my BBB. I see what you're saying but if I wanted shiny I wouldn't have bought a bronze watch

    My late father was a mechanic for road racers in the Manx GP / other clubman's events back in the late 70's / early 80's.

    The used to soak seized pistons etc. in Coca Cola (full sugar of course) in Coca Cola overnight to remedy them.

    I always remember them saying "God knows what it would do to your stomach."

    As kids we used to leave old coins overnight in a saucer of HP Sauce. Used to come up a treat.

    It must be a case of whatever you use, it needs to have a lot of acid in it.

    On the contrary, a mild acid is what’s needed, hence things like ketchup, brown sauce etc.

    Think the issue is you said it needs to have a lot of acid in it.

    Sauce contains acetic acid from vinegar - a weak/mild acid. Not a lot though!

    Important thing is not to use a strong acid (like hydrochloric), not whether there's a lot of it or not.


    Personally, I like the look of bronze but not the patina.
