Restore patina on antique brass sink basin


A discussion started in 2006 but continuing through 2018

2006

Q. I recently purchased a decorative bathroom vanity with an antique brass basin. I had a plumber install the vanity sink. However he had to do some work under the basin using a blow torch which took the finish off the surface in the center of the exterior basin most likely due to the extreme heat. Can anyone offer help to restore it back to its original color?

A. There are a BUNCH of letters with patina recipes in the archived letters. Just use the search engine to find a few and you should be good to go.

If it is going to be a functional piece, I suggest applying a clear coat so that your cleaning doesn't remove or affect the patina every time. There are suggestions for clearcoats in the same letters you'll find looking for patina recipes.

Good luck!

Q. I have a similar problem with my antique brass finish on my sink. I had some bleach cleaner remove the antique finish and now have a shiny ring.

I looked in the past archives but did not see how to restore my finish properly. A lot of articles on keeping the finish, cleaning properly, and what not to use.

Thank you for any assistance in this matter.

Q. I purchased a bathroom vanity with a antique brass finish sink. I used Brasso [linked by editor to product info at Amazon] cleaner on the sink and it removed the antique finish. I now have a shiny brass sink. I wanted to know if there is any way I would be able to restore the finish myself and if so what product should I use. I also want to know if I should seal this with a clear coat after restoring and if so what product would be preferable. Also after completing this restoration what is the recommended product to clean this. Thanks so much for your help.

Q. I have two brass sinks in my master bathroom. They are 2.5 years old. My husband's is still brand new looking but mine is terrible. I use contacts and I think the solution has lifted the matte finish to the sink and it is now terribly spotty where the finish coat has been damaged. Also where I have spilled toothpaste there are green marks here and there. What can I do to repair this problem.

A. Hi, Karen. First you need to get that clearcoat off. Try lacquer thinner [linked by editor to product info at Amazon] first. If that won't remove it, you may need Aircraft Stripper [linked by editor to product info at Amazon] (very noxious stuff -- make sure you have really good ventilation, goggles [linked by editor to product info at Amazon] and protective gloves [linked by editor to product info at Amazon]). If you succeed in getting the clear coat off, you should be able to repolish and try a fresh coat of brass lacquer [linked by editor to product info at Amazon]. Good luck.

A. Hi, Noel. When you say "outlet" are you referring to the drain fitting in the bottom of the basin? If so, and if it's not really something special, I think you'll save money and time by simply replacing it. This is an easily replaceable part made of a thin gauge of brass.

As for cleaning it, if brass polishes don't work, vinegar+salt+flour probably will, but may leave it very orange colored, which can be corrected with a few applications of a commercial brass polish.

The thing is, brass doesn't stay bright: it tarnishes very quickly. If it was ever bright it was because it had lacquer or a clearcoat on it. Good luck.

Q. My 130-year-old Victorian house has a tiny bathroom with a pedestal sink that will be replaced. But it has brass-looking faucets - the kind with white enamel knobs - that I want to keep for the new basin. However, the faucets have a mottled look that no amount of polishing can change. How can I get these lovely faucets back to an even coloration?

Q. Brass Sink!
I have a customer who has a very tarnished brass sink... I am unsure what to use to clean it without ruining the finish. Please help!

A. Hi Sonia. It's hard to offer advice without a photo because there's bright brass, dull brass, antiqued brass, and oil rubbed bronze. Even then, your sink may be solid brass, or it may be brass plated; it might even be bright nickel plated and topped a translucent brass-toned lacquer.

When you say you want to remove tarnish, we assume you mean an uneven brownish discoloration that reduces the bright brass shine. I think the safest approach is to remove any lacquer coating with acetone, then polish it with Mother's polish on a buffing wheel attachment with a low power battery-operated drill. Then apply brass lacquer in 3 or 4 thin coats. But sometimes it's not salvageable because the bright brass color is just plating or lacquer. Good luck.

A. Once the lacquer is removed (if there was any), citric acid is a good alternative to polishing for clearing up the tarnish.

Q. I recently purchased a vanity with a brass sink. I am wanting to clean the sink and remove the spotting and tarnish without stripping the patina off completely. I do not want this to be a shiny polished brass look, but keep the antiqued brass pastime without looking dirty. Any suggestions will be greatly appreciated!

Thank you,

A. Hi Kelli. I hope I'm wrong, but I think it's hopeless to try to save some discoloration and remove other discoloration; I think you'll have to take off everything then restore the patina. I really don't think any chemical is going to know what you want removed and what you want left in place.
