How do you keep bronze bright?
You could polish weekly. I've also polished then sprayed with 10-15
coast of clear polyurethane, and they will stay "shiny" for a few months, but you'll be sorry when they finally tarnish and you've got to take all that PU off. There is a new product called Nyalic that seems promising, but I haven't tried it. http://www.nyalic.com/ |

Hi, I recently polished up the bronze fittings on a small skiff. It took less than three weeks for them to turn brown and green and scuzzy again. Do you have to polish weekly or can you paint it with varnish or urethane or something? Thanks and keep sanding. Here's how to keep your bronze bright and shiny for a long time with ordinary care etc., etc. [scroll down] Ready? [scroll down more] Have them gold-plated Brian Whatcott |

For exterior bronze:
Mechancial polishing using jewelers rouge and a high speed buffing wheel, followed by several heavy coats of 2-part (catalyzed) acrylic/urethane clear. For me this lasts about 2-1/2 years - if the coating remains intact. When the coating eventually fails, simple paste type paint remover will lift the acrylic/urethane ... a light power-buff and recoat is all thats needed for another 30 months. If you use 'chemical' polishes you must totally remove them before coating, etc. Dont bother with spray-on clear urethane or clear lacquer as its too air/water vapor permeable and will allow re-tarnish in a ust few months. Otherwise..... rub on a mixture of lime juice, beeswax and olive oil ..... will turn the bronze to a golden brown and will prevent the 'green' from forming. The 'ancients' used this formula to coat their bronze; when they needed to 'burnish' or polish they simply added fine pumice to the mix and rubbed hell out it. |
