Birchwood Casey Brass Black Metal Finish, 3-Ounce

Have used on clean brass. Gives good pitch black if the surface is cleaned nicely. After some months it was not giving good black. But patches. Especially in monsoon so moisture and dust if avoided, it works great

I compare my need for this product to someone giving themselves a bad hair colour job, where after they've made the mistake and have horrible yellow hair, they are trying desperately to find a way to bring it back to its original colour! In my case, I have an old brass door knocker that can be dated loosely between 1945-1975 (LOL). I'm in the process of updating my front entrance door and thought, hey after 25 years maybe there's something nice under this black stuff. I send a picture to my brother and he said, it could be brass. Without thinking, I took my SOS pad and in seconds was able to remove the black to reveal brass thinking I found treasure (and sent him the photo of it partially sanded and then... about 30 seconds later I was like... "OMG, now I've done it! I really want it blackened! What am I going to do?!" So to the internet and Amazon I went so fix my mess. I figured someone must have discovered a way to do it by now and someone did! Birchwood Casey. This product worked like a charm! I actual found it is more commonly used on guns (gasp), but that it can work on any brass metal object. Here's how I did it. - I first wiped down the knocker with acetone to remove any residue. - I then soaked cotton pads, wiped the surface with Brass Black let sit for about 2 minutes and continued to applied several applications, while letting in dry in between each one. - I let the whole thing dry for about 5 more minutes then washed under water. A tiny bit of black came off but nothing notable. - I held it up on my door to take a photo and show you how well it worked! Take a look at the photos! It's actually funny how I have a picture of each stage as I was so excited, full or regret, then excited again. If you have questions, be sure to ask a question vs. comment as Amazon doesn't send me messages when comments are left.

I used this as an experiment on an old solid brass round door knob that had been scratched and old looking for 20 years. I had to remove the last scraps of lacquer first, and then followed the directions and immersed the knob. It turned the color I was hoping, the gorgeous oiled bronze look which is what I was going for, and why I give the product 5 stars. Unfortunately some of the dark coloring has rubbed off in odd, patchy spots on the edge of the round knob, but I really can't say if it was my fault for rushing through the process or the products fault, or perhaps brass that is not evenly mixed. I have more knobs and other solid brass items, so will experiment with them and see if there is a better process and update this as I learn more. By the way, I also bought the oil rubbed bronze spray paint (metallic) and sprayed another brass knob, the kind with the handle to the side instead of round. It is under some use on a bedroom door and has held up really well, and looks fine, but no where near the patina this gives. Despite that, I will likely paint the majority of my knobs because it seems silly to replace them to update my house look when I can easily paint them, thus saving more stuff to be dumped in the dump and environment. I will use this product on my front door knob and plate as I like this look better, but cleaning off the lacquer was more arduous than I liked, as I tried rubbing alcohol (worked on one know, not the other), mineral spirits ( worked on the other knob) and lacquer thinner (helped but did not work well). Apparently finishes have changed over the years and trying to figure out what to use to remove the stuff as well as the actual scrubbing is a bit more energy than I want to do for EACH knob, thus the paint on knobs that are not easily seen. If any one has any ideas on how to make that removal easier, I would love to hear about it.

It works very good, to turn the brass black as it should. Did prep as direct and have a very good end result. If you are trying to remove a brass mark from a pin or punch strike this is what you should use.

Used it on laser-engraved coins. It gave a great finished look.

Works after several applications.
