Most of your work is counter active. The proper way is to simply let it soak in the vinegar (which is acidic). You can add regular table salt and it will swing the ph so it work faster. One tsp to quart roughly. Then let it soak for 30 minutes. Things like car copper radiator that is thin, you spray it on only for 5-10 minutes. Then light brush work if needed. If it all doesn’t come off easily, soak longer. Then once clean, this is where the baking soda comes in. Mix some water and baking soda and rinse off the acid (vinegar) to neutralize it. Then a rinse of just water. Adding the baking soda directly to the vinegar is just the baking soda killing the effectiveness of the vinegar. Those bubbles are not cleaning anything. They actually make it worse and is corrosive in itself. Any welding supply shop when asked can shoe this. Compressed cylinders for things like oxygen, carbon dioxide, argon, etc. - the expensive containers only can be used for caron dioxide once it has had it i. There one time. Because it corrodes the tank. And the pressure testing for those tanks is a shorter time intervals because of it even though the content is non flammable. You can take “dry ice” which is carbon dioxide in solid form and use it to scrub copper, and you will see there is no cleaning value, you will actually see it begin to corrode the material. In science lab class this is a demonstration used to make the new copper become green from speeding up oxidation.
I meant to add, An experiment if you want to prove what I am saying is find a small piece of copper tubing that is corroded. Cut it in half. Do half the way in the video and other half the way I say. Mine will be amazingly shiny with soaking for an hour and a quick brushing then baking soda rinse. Compared to his/her 24 hour soak. He/She soaked for 24 hours because the amount of soda added weakened the vinegar so radically. I hope this helps, and in no way intend to insult the maker of the video. I think someone probably explained it to them incorrectly.
@@advaitkulkarni2513 I don’t have time unfortunately. But searching RU-vid should find some. Glad yours is good now. Maybe if you have time, make a video teaching others now that you have seen it.
I just bought 3 old copper ornaments. I already have the ingredients. Yay. I'll be using this method. Thank you😘💕... Love from the Scottish Highlands ✌
Hi, I am very glad to hear that. When you try to clean copper please leave feedback. Thank you very much for following my channel. 😘 Love from my channel.
I gave this a shot, and came to the conclusion that the baking soda and salt are of no use. The vinegar and soda are acid and alkaline, and cancel each other out, with salty water as a by-product. I stood my pot in this mixture over night, but there was no evidence of cleaning at all. However, I mixed together tomato ketchup and vinegar, and smeared that around the inside of the pot; the ketchup served to keep the acid on the surface, rather than running off instantly. Within hours all but the worst of the tarnish and green corrosion had gone. The down side is that now my hands stink. The only possible value in using soda could be that when the bubbles form, they form under particles of dirt and corrosion, thus forcing them off - just like false teeth cleaner. Also, the bubbles from the chemical reaction is fun.
i used vinegar alone on a copper coin and it corroded it, while on bronze coins it worked perfectly. it may depend on the alloy but i think vinegar alone on copper isnt a good idea
@@MARK-gp9hb Vinegar that you buy for cooking is only about 10% vinegar. While this is an acid, it isn't at a terribly high concentration so it won't corrode things (or at least, not quickly). In this case, that doesn't matter though. The salt and the vinegar react with the copper oxide forming an ion of copper. This ion dissolves in water. So, as the reaction takes place the copper oxide is transformed into a copper ion which dissolves in water. The copper that isn't already oxidized (the metallic copper) doesn't much react with any of these things. And the tiny bit that does react will be broken down into that copper ion and dissolved into the water.
But it creates Co2 which when dissolved in water creates carbonic acid which can remove corrosion in a milder fashion than acetic acid. But since it's just CO2 in water, you might as well just use soda water. Coke is great too since it contains the addition of phosphoric acid. Molasses also works. Just make sure the metal is fully washed and sealed with something to prevent further corrosion
do we need to left it for 20hour+? i only leave it for 10min.....don't know is it need to do with time? my copper i do the same as the video but after 10min patina start to form again
Wow, that looks like what I need to use. I have a cedar chest that has copper decoration on it kind of making it look like a trunk. I decided to try to clean them and just realized they were copper, but I'm scared to get it too wet because I don't want water getting under it on the wood. I will just have to be careful. It looked black like the outside of this pot.
Hi, sorry for my late answer. Cleaning with this method is very easy. After finishing you need only to wash copper with clean water. I have a lot of copper stuff I use it for my garden for flowers and there was no problems with corrosion. But I love the blue/green patina on copper it gives old rustic look.
Corrosion in this case is actually oxidation, so no it doesn't harm it like rust does to iron. In a lot of case, like with aluminum, the oxidation can actually create a protective layer.
Thank you for feedback. I am aware that music is not so good. I hope that in my new videos I will choose better music. Feedback from viewers are always welcome.
Hi bro, maybe some other video will be more interesting for you. I do not have much free time for videos but giving my best. I have prepared a lot of projects for this channel I hope that some of them will be interesting for you. I appreciate your comment. Thank you John.
I know the patina created for oxidizing protects the structure over time, but if you polish and remove the oxidized layers, are you essentially removing layers of metal and over time it will diminish? Like a hardwood floor refinished over and over?
Dear, You have spent 24 hours and wasted to much of materials and did scrubbing. Please try with tamarind. Make past with water. Apply on top of coper. Let it in 30 min. See the result. It's easy and not much cost. Thanks
Hello, thank you for watching videos on my channel, I will try to clean copper with tamarind and also to share video on youtube. Your support and comments mean a lot to me. Thanks
@@-CrampedStyle- Google is your friend :-) Make a paste with this plant and a bit of water is what I think the OP means: en.wikipedia.org/wiki/Tamarind
my parents house is cursed with copper handels on every door that makes your hand smell like old coins, and it is going to be a pain to remove and clean all of them :8
The residue left behind when copper reacts with vinegar and salt is extremely toxic; it should be brought to a hazmat facility and not poured down the drain.
