A discussion started in 1998 & continuing through 2017

(2002)

A. I am polishing a solid brass bell, and it's tiny-creviced hanger, on a sailboat and found something much better and thicker than Brasso. I initially bought it because it is in a sturdy plastic bottle. The brand is Burnishine Copper, Brass and Metal Polish. The polish company is in Gurnee, IL. The rest is just elbow grease, then a polishing wheel and CLR [linked by editor to product info at Amazon] polishing stick.

A. Do not use ammonia or Tarn-X on brass, it is not good for it.

A. What I have found that is great at removing tarnish from brass is CLR [linked by editor to product info at Amazon] This product is used for cleaning bathroom scum from tubs and sinks. CLR contains Phosphoric acid which I read earlier in the responses is great at removing tarnish from brass. I have an old brass ceiling lamp that was heavily tarnished and this stuff worked good at removing it. I had to soak it for many hours for heavy tarnished brass before it would remove the tarnish, but what a difference afterwards. I think I'll use Brasso to polish it up.

A. For any metals, jewelry, brass, silver, chrome ANY, use Hagerty 100 [linked by editor to product info at Amazon]. It does miracles to the worst of tarnished items. It cleans and polishes with no rinsing. It is great...

A. I have read through 95% of these; we have two 100 year old brass light fixtures. I was at wits end about how to clean them. I tried the Dremel [linked by editor to product info at Amazon] w/Brasso...ketchup....vinegar. Before going out to buy another product, I tried this: Lysol toilet cleaner. Jackpot...in the BIGGEST way. It took me an hour to clean the whole thing by hand ... minimal elbow grease, little nooks and crevices, the whole works. Finish looks very cool; like antique brass. We are VERY pleased! We are restoring a Victorian house, and desperately want to keep the fixtures, and now we will be able to.

A. The best way to restore brass, bronze or copper items is to have them refinished professionally. You can look in your yellow pages under metal finishers or plating.

A. Brass! what a pain to clean; the ketchup trick works for some unknown reason and try it as it is fab. There are many other mixtures you can make from household substances but ketchup is the best for brass. Others I have tried which worked, but not as well, are: mixtures of salt vinegar and flour. or lemon and baking soda [linked by editor to product info at Amazon] or vinegar and salt. or lemon juice and cream of tartar. or Worcester sauce. or toothpaste. (but please note only use clear vinegar as the brown stuff cause a weird pink reaction to the brass!) But as for other metals and also for removing the lacquer from brass there is one simple answer and it is unbelievable to watch! Take and plastic bowl place household kitchen foil in it covering the inner sides of the bowl and fill with warm water(not hot) and add soda crystals (these are found by the washing powders in the supermarkets) to the water allowing them to dissolve then take your gold/ silver/ brass object and submerge it in the water. It takes seconds and all the grime tarnish and dirt just comes straight off the foil attracts it all. You are left with beautifully clean objects.

Please note : if using this to get rid of lacquer leave in the substance slightly longer but beware it does not work on gold or silver plated objects hope these tips help!

Q. Hi--

I am a retired guy who restores the old copper soda acid fire extinguishers and I notice from time to time I polish one that appears to have "tiger stripe" copper. Please provide some information on this copper--history, production process, why and when it was used on fire extinguishers.

Thank you ,

Q. I have a pair of old evacuation horns that are tarnished. The horns are brass and the brackets are either copper or maybe red brass? What would be the best way to get them looking like new.

Thank you,

Q. I saw TARN-X at my local grocery store, Giant Eagle. it was with the cleaners. I looked at it to do an eagle project where I am restoring an American Legion honor roll. It said on the back not to use it on brass though, I was confused about this.

Q. I have tried Brasso to clean my brass ornamental kettle but it isn't working. Does anyone know how I can get it clean.

thumbs up signI have used Mother's Mag & Aluminum Polish [linked by editor to product info at Amazon] on a brass bar counter & railing, it works the best. Brasso I don't like. I have to try ketchup, it is cheap and sounds like it works from everyone who has tried.

Kathie Nystedt

(2005)

A. Like most people posting, I've tried many things. What I've found is that ketchup doesn't boil well. You end up with a mess. It does, however, remove the tarnish. I've tried lemon juice and found it to be mild. I tried Brasso and Tarn-X and some other store purchasable brass product. None of them removed the tarnish easily. I also tried a grinding buffer and the Dremel. Not a fan of either and quite expensive in the long run. I am cleaning all of my brass on a grand piano, including a 56" hinge.

I found vinegar works the best so far. I soak it overnight and polish with Brasso the next day. Then I clean it and soak it again. The pieces are around 100 years old.

My Dad, a Chemical Engineer, said all of these home remedies contain acetic acid and that's why they work. So anything with acetic acid will work in the same way, and the higher the concentration, the quicker it will work, however, it is burning off the layers, so don't leave it soaking for too long.

A. When I was in the Navy I would use stuff called Nevr-Dull [linked by editor to product info at Amazon]. An easier method is to use a drink aid like kool aid. just match the color of the drink aid with the color of the brass or copper. Usually orange or yellow works well .

Good luck.

A. To clean brass and copper that is very tarnished use coker and a small buffing wheel attached to your power drill. It works quickly and puts a shine on it that you can not get by hand cleaning. The coker (coke-ker) and buffing wheels are cheaper than chemical cleaners and can be purchased thru WW Grainger or check with your local bumper nickel plater. They can also tell you what grade (like Sandpaper [linked by editor to product info at Rockler]) you will need. Be careful the metal gets hot easily. Once you have it all cleaned, wearing gloves to avoid finger prints, simply put on a coat of turtle wax (car wax)and buff just like you would a car. Your items will stay shiny much longer and the wax is easy to remove when its time to polish it again.

A. I had been struggling mightily to clean an old antique brass and crystal chandelier which we purchased in Europe. It was absolutely brown with oxidation - it looked more bronze that brass. I could see that scrubbing with Brasso [linked by editor to product info at Amazon], Wenol [linked by editor to product info at Amazon] and Flitz [linked by editor to product info at Amazon]was not a long-term answer - instead I was headed for a case of carpal tunnel syndrome or arthritis. So, I decided to search the web for a better way and arrived at this website.

Of all the concoctions suggested, I elected the one closest to where I was working on the piece....toilet bowl cleaner [linked by editor to product info at Amazon]! I squeezed a little on a paper towel and applied to an arm of the chandelier. To my amazement and glee, the oxidation literally disappeared! Honest....I'm really not kidding! It worked in seconds with virtually no elbow grease. Immediately after cleaning off the Lysol, I reapplied the Wenol to finish the job and bring out the true colors of the brass....this is just too cool!

Thanks to everyone for all the suggestions you've shared!

Q. For all those confused about Tarn-X, there are several different types. One of them is called Tarn-x Brass Glaze. All of the other types are not meant for use on brass. This has been more difficult to find because fewer stores sell it, however, my local Ace Hardware has it. Hoping it will work...

(2006)

Q. I just hung up my brass chandelier that has been put away since 1978. I was excited to get out that I use Tarn-x on it, thinking I used it before on brass. I read the bottle when it was too late. It now has ruined my finish. What can I do?

!! I own a brass antique chandelier. It was purchased in 1968. By mistake it was cleaned with silver cleaner, which took some of the finish off. I wrote this site once before. What can I do about this?

Michelle Homewood
- South Bloomfield, Ohio


(2007)

Sorry that no one responded, Michelle. Unfortunately, the situation probably has no clear answer, plus similar questions have been answered here hundreds of times before, so the readers probably had nothing definitive to say to you.

If it was purchased in 1968 it probably had real brass plating on it. Apparently this has been scoured away in spots. Brass plating is impossible for a homeowner to re-do for themself, so your options are probably limited to sending it to a plating shop for replating, painting it with a brass colored paint, or trying a Rub'N'Buff [linked by editor to product info at Amazon]. Good luck.

Q. I have an old brass chandelier, and it is very tarnished. I am looking for a way to clean it without harming the wiring in the arms of the chandelier. I am concerned that any cleaner might short out the wires. I do understand that when I clean the chandelier, that it must not be connected to electric!

thumbs up signHoly criminy! Ketchup works! Just wanted to let the fine gentleman know further down in this board that his recommendation for ketchup for brass tarnish removal was fantastic. I have an intricate brass dragon that store-bought brands were hardly touching. I coated him in ketchup, let him set for about an hour and removed all the ketchup from the nooks and crannies with a soft toothbrush. The dragon is back to his flaming beauty. Thanks!

Holy St. George! But please remember that, gentle as Ketchup (or vinegar and salt) are on people, they are extremely aggressive to brass. If it's a robust brass article, it's probably fine, but these materials can harm delicate items

A. I have been restoring brass cash registers for 20+ years and find that coating lacquered parts with 'Gunk' for about an hour before washing and scrubbing with a soft bristled brush in hot soapy water works great.

Q. I have a brass ships bell, with an inscription reading 1949.It has a finish on it,but spite of this it has become dark in color. I would like to take the finish off, shine and re-finish the bell. Do you have any suggestions for removing the finish?

A. I know where you are! I have restored 200 brass cash registers.
First buy some silica sand and blast them. won't hurt anything even the indicators.
After blasting them, buff them with a bar polish, them clean them with some soapy pressurized foam, then return to the polishing booth and polish it with a bar of red rouge. clean again then spray with a clear lacquer. works every time!

thumbsdownHi, Alan. We appreciate your success story. But after 40+ years in the metal finishing industry, cyanide, hexavalent chrome, concentrated sulfuric acid and all the rest scare me very little. But hydrofluoric acid still terrifies me. I wouldn't let it anywhere near my house!

A. I restore brass NCRs as a hobby and polishing them is not an easy and fast process. First, every piece of brass must come off. Next you have to get all of the dirt off by putting some water on it and Comet or Lime Away and scrub it with a tooth brush. Next you have to get the old lacquer off the brass by putting paint stripper on it and leave it on for fifteen minutes then pour boiling water on top of it and, instantly after, carefully grinding it off with a powered brass brush. I like to use a hand held grinder with a brass wire brush in place of the grinder. Do not press too deep into the brass -- all you want to do is take the lacquer off it. It will brighten up a ton, but that's not the end. Then with a bench buffer you need two different types of buffing abrasives. First buff the brass with tripoli then finish it with rouge. Both on different cotton wheels. Finish it all of with a thin layer of lacquer and there you go. Hope this helps.

Q. I know that this site is primarily about metal finishing but you all seem to know so much about NCR's. I acquired an NCR and was able to un-jam one of the numbers but now the key is locked in place and won't come out and all the numbers are locked and won't move as well as the drawer I can not get the drawer to go back in and stay in place in locked position. I'm at a stand still. This is an old metal register not the brass one. It is model #FR-867635-TT. Thank you for any help that you can give me.

Q. Where can I go to find blueprints or something on rebuilding a cash register? My grandpa had a cash register that he took apart to clean but never got around to putting it back together. I have it now, but have no idea where to go to get it put together. I would like to finish what my grandpa started. Please help.

Q. Can anyone direct me to a site where I can purchase a national cash register model 332 Manual? I need help with my 332. When the keys are depressed the drawer will open but the key will not return. It requires me to lift the key by hand. It needs some kind of a spring. I sure a manual would be helpful. Also where will I purchase it.

Thanks,

Q. Hello, I am having almost the same issue with my NCR. I purchased my NCR from an Estate Sale and the previous owners painted the whole thing in multitude of colors. The paint is so thick the first panel I cleaned took me a couple of weeks just to get the paint out of the groves. Can anyone please tell me a way I can get the paint off faster with out damaging the brass? I would love to try the Vinegar and Boiling water, but can't get a pot big enough to fit each panel in. Thanks

Maas metal polish

March 17, 2017

A. I've been working on restoring OLD instruments (a early 1950's sousaphone, an early 1900's alto horn, and a 1941 trumpet) and have found by far the BEST polish is Maas Metal Polish. (I've used Brasso, ketchup, vinegar and salt also).
Maas is a little more expensive than the others, but in my opinion well worth it.

Servicing NCR Drawer so it shuts

August 15, 2017

Q. I know I may need to join a club and pay a fee, but I am very new to this.

I just purchased a very rare fine scroll #5 National brass candy store cash register.

It was made in 1903 with a number #808206 on the face and under the drawer.

This machine is missing the top purchase plate and the drawer will not latch shut. Otherwise everything seems to work well.

I am looking for advise on how to service/fix the drawer so it works properly.

I know I will probably have to take the sides and back off to perform the fix, but am looking for advise to ensure I don't cause additional problems.

If you can assist me with this I will be very grateful.

If you require a fee please let me know.
