There are some pieces that devalue when you remove the patina. Natural patina enhances the beauty of a piece, like this close up of an antique French Demilune table. The brass pierced gallery is wearing an untouched natural patina..( soon to be in our Chairish store.) It has aged appropriately along with the mixed wood marquetry. To make it shiny bright would devalue and detract from it's beauty.
This is an antique hanging light fixture from the flea market that I did a couple weeks ago.It had a major amount of verdigris setting in.
After that I applied a paste of white vinegar and baking soda to the corroded area. This mix will remove the verdigris from the metal, I then add a bit of salt to the brass and rub it well into the area to act like an exfoliant because verdigris is somewhat crumbly and thoroughly wipe it off using the wipes again.
I wiped dry with a lint free cloth and gave it about 30 minutes to make certain all traces of dampness are gone.
Then using a dark non toxic wax intended for chalk paint, I rub down the brass. Areas that are too dark can be lightened with clear wax. I let it sit about 3 minutes then wipe off. The dark wax fills in the natural pitting that occurs in aged brass and seals it from developing more verdigris. And it adds more depth to the brass which is what I really love. If you want a more matte finish let dry and buff it up a bit. If you want a shinier finish you can seal it with a micro crystalline wax likes Renaissance Wax. I left mine in a matte finish as I prefer the additional warmth and depth of the matte look.
Until next time...
