So I have dug some old bronze, copper, and brass items in marsh area as well as sodium rich areas. Many of them seem to develop bronze disease. I am in the process of soaking a bridal rosette and a clock part in a sesquicarbonate solution at the moment as well as some copper pieces. It is a mix of about half and half of washing powder and baking soda. I figure a few days in that should help. I am going to try soaking in Benzotriazole and ethanol (some Everclear) mix for a few days as well to soak into the cracks and add a protective layer.
For the final coat, I am not sure if I should add an acrylic lacquer (water based) modge podge spray or clear enamel from Rustoleum (oil based) for the final of these bronze, copper, or brass pieces that are getting bronze disease from being dug up in a marsh/ sodium heavy area. Any thoughts? I have seen some preservation sites recommend the acrylic method and nothing on an oil enamel.
I have Renn Wax but hate how much it costs. I plan to save and use only on colonial coppers and flat buttons. Just the little really old small stuff.
