My mother once restored her heritage silver spoons, forks and knives by just boiling them in an aluminum kettle, using just a small amount of ordinary (iodized) table salt in also small amount of our quite hard tap water. The silverware had been tarnished due to little use and no protective paper wraps or anything. Previously they had been occasionally cleaned by some mildly abrasive paste, but that was tedious, one piece at a time. Moreover it removed some of the precious silver. This salt and aluminum method was in effect a bulk operation and also did not consume any of the silver.

That reminds me of when I was a kid watching Mr. Wizard. A dramatic effect explained by science. Bravo!

Taking a corrosion course currently, this is so interesting. Cheers, man. Loved it!

4:35 Moments like that are why I love chemistry. Great video, as usual.

I'm delighted and enlightening by the science. Please don't stop making these types of vids. I really enjoyed it :)

Awesomeness happening before our own eyes! Thank you for sharing it.

This is amazing, thanks for all the work you put into your videos!

That was EXTREMELY cool. I had no idea this was a thing, thank you, as always, for your informative and interesting content!

at Robo t Slug - yeah Rob , it was really cool This man has accomplished what the alchemists wanted to do, turn the sulfer into gold or silver... this is done by getting rid of the sulfer from the silver and gold coins.. making them like new is the best way to create valuable silver and gold. if we can market the sulfer or the dirt as intrinsic value then its got more value more value than silver value, but we can pay this for shinny silver or gold coins too.

4:38 I can already see this becoming a trending gif

Best silver cleaningvideo I've found. Thanks a bunch

Wish you were my chemistry teacher back in the day! I would have had an A+ instead of a B! Love the content, keep the videos coming!! Thanks!

Love this stuff! TY for taking the time!

That is very educational video. It will also make people better understand why steel does not corrode when coated with zinc layer or in contact with a zinc object. Your example is so fast that it is much easier to observe than slow steel corrosion process.

Try the reverse, since the electrical potential is -1.66V you're creating a battery with the tarnish and the aluminum. Try illuminating an LED or something similar with the recreation. The current is probably extremely low but you might be able to get it to work.

Shouldn't the cell voltage be -0.69-(-1.66)=0.97V? That wouldn't be enough to light an LED.

I think he is saying those are two different reactions with two different electrical potentials. So one is 0.69, the other is 1.66, they aren't done at the same time. He used the one with the higher voltage because it works better and is faster for reducing the coin.

Wow, this is just amazing. The reaction is so fast.

Thanks man did this to my mothers silverware set, she was so happy to not be using a rag and buffing compound, did a full set in like 5mins, although she wasnt to happy with the smell of the kitchen afterwards.

Great video,You don,t waste our time and you taught me a lot very quickly.

very cool demo & explanation.

Wow! I enjoyed this very much!! Thank you for posting.

OMG Thank you so much for this video. My silver expensive jewellery got very tarnished (turned dark purple bronze colour- was super panicked) in washing powder solution whilst hand washing some soaked clothes. Tried the baking soda solution on foil in a glass bowl with hot water didn't really make a difference.... Started to look online to buy a silver tarnish product. Came across your video followed your salt/ Baking powder instructions within 10 seconds I kid you not, I couldn't believe it. My jewellery is now gleaming...Thank you so much.I will donate to you the cost of the silver product I was seeking to buy online. Thank you.

Great experiment. I'll be using this on my silver.

Great presentation! I just subscribed only after the 1st video. Can't wait to see more like this. Thank you

This is great. Well done!

Thank you! I just cleaned 15 years of black sulphide from our teapot using this method in a bucket. It worked brilliantly while I found I could 'encourage' the process by rubbing the stubborn parts with bicarbonate powder.

Your videos are great. I look forward to new ones. I'd suggest covering new reactions rather than revisiting the old. Technical discussion of retrosynthesis would be interesting, as would some heterocyclic syntheses.

I did this with my kids yesterday. Amazingly easy and fun to watch.

Great video. It would be great to see a video on copper plating coins of different metals, or perhaps nickel plating or aluminum plating such coins.

I just did this experiment today, and it is amazing. I use it to clean some of my wife's expensive toys and it worked so nice. I did a small alteration that did increase the reaction speed, a few seconds on the microwave :D that resulted on a reaction as fast as the electrolisis process

Awesome work! Keep it up!

That was very cool, it looked like it was oxidizing the copper in your wires too in the battery example

Very Nicely Done ! 👍

Love the videos! You made me love chemistry!

*Watches in 480p anyways* Thanks for the great videos! I've been a loyal subscriber since 2010. Keep it up!

I really enjoyed this one.

Thanks for this, especially 3:57 onwards. If only I'd known about this back in the '80s!

Please do more videos like this one. Using different chemicals and different metals👍

That was amazing.

Well done 👍👍Great video 👍👍Thanks 👍👍

Interesting video..Thank you for sharing💖

Thank you so much for making this video.!!

Loved it. Thank you.

Wow, your video was very well done, and more informative than I could handle! Thank you. I've a question that lead me here in the first place, perhaps you could help: I was wondering if something similar would work on a carbon steel knife. Carbon steel oxidizes \ forms a patina when it comes in contact with moisture, and even more so with acidic elements. I've often used baking soda mixed with only a few drops of water as a slurry to rub deeply against the steel and thus remove the patina. Would iron \ steel enjoy the same process that silver does? Perhaps some metal "lower" than aluminum? Did this make sense? Thank you for your help! Dan

I like it! Good job!!

Never thought that just two metals​ touching each other would be enough to completely get rid of the tarnish. You always learn new stuff, and the awesome thing is that you get it basically for free. Thanks for sharing! Oh forgot one thing, does someone know how to get rid of rust on iron/high carbon steel caused by hydrochloric acid? Tried polishing and rust removing agents but you can still see the orange/brown stuff caused by the HCl. I would highly appreciate it if someone knows​ how to get rid of it!

very cool really enjoyed this!

That was awesome!

amazing video ...thanks

Great video. So what happens if you leave it to be electrolysized(?) for a long period of time, or even do it 2 or 3 times? Will it improve the look? Thank you,

More electrochemistry please

Works great on old Or tarnished jewelry!

amazing video

Excellent.Keep it up.

That was neat, thanks!

That's some good chem right there.

That was awsome!

Excellent !

Loved it!

Wow thats really cool!

Dopeee love to see you drop a new video. Cool as ice too lol

This is amazing chemistry in life!!

INCREDIBLE

Yesterday i was In a mineral bath and my silver pendant stained itself instantly, this vid Will be realy useful.

Amazing reaction! I have never expected a electrochemistry happening so fast! I have a question regarding to this reaction though. Are the H2S introduced by yourself, or is it a common contaminant that attacks silver?

Brilliant!

Utterly fascinating! I found several silver items in an old well. They are badly crusted with something - not mud or dirt but something that steel wool won't budge. I am going to try this in the hope it might work.

Wow just wow. I must own no less than a kilo of heavy solid silver jewellery that I like spotless. And yes you guessed I hate hate polishing cleaning. So going to try this. Thank you

Awesome 👍👍👍👍

You gotta warn people about the smell! Doing that reaction releases malodorous sulfur compounds. It’s a good experiment to do outside.

It was taking to long to shine one of my bugles so i tried this though i used a method similar to brush electroplating, Its amazing how fast the reaction was. Instead though i used a 9v battery not a pack

Perhaps a redo of the "Get Lithium from a battery"?

This has been a great help for me, in my cleaning of silver plated and solid silver flutes. They have fiddly bits that are hard to reach, and so this method is a great help. I sometimes have a gold plated onto silver area, where tarnishing on the silver below is starting to show through. If I use this method, would it remove the tarnish on the silver below the gold plating, without damaging the gold plating? Thanks

Would this work the same for 925 silver? (commonly used in jewelery) or would it have some other kind of reaction since that silver isn't quite so pure?

Awesome👍👍👍👍

We have been using this to clean silver ever since in our household, but we only used salt, no baking soda and it worked fine too, does the baking soda really make such a big difference?

OMG that was AMAZING! Science is so cool! ^O^

@NurdRage Were your fluorescent dyes made in 4k? The colors were brilliant nonetheless.

Hey NurdRage! I know nearly nothing about chemistry but I really love watching your videos. I was wondering what gas was being produced by the positive wire going into the solution. Some gas bubbles also formed on the coin itself.

Really neat! Thanks

So if you leave the battery setup running in solution for a while, would you end up with a coating of whatever metal the wire is made of (I'm assuming copper) as the anode is oxidized to ions in solution? If so, is there any choice of electrode that'd avoid that?

I'll gladly re-watch any video you want to make again in high quality!

What would happen if you'd keep the silver coin in after there is no silver sulfide left on the coin?

This was great, does it work with silver utensiles?

pretty cool

that was pretty kool

COOL!

Would this work the same on metals that were treated with a solution to add tarnish via patina?

No matter how many times I see that happening, it feels like the first time as a kid seeing the silver clearing in front of your eyes.

Nice 👍👍👍

He did it, nice.

Cool!

Cool!!

Does the reaction produces electric current and measure it if we're using copper wire connecting the silver and the aluminum foil rather than making them touch directly?

Hi, I was very excited when I watched the video. I work a lot with silver and tried the method with the batteries today. I used a 9 Volt battery and tried it on a spoon. I used cables with crocodile clamps. It was heavily bubbling and the water turned almost black which got me thinking it works for me too. However: The spoon is still dirty but the positively charged crocodile clamp fully dissolved in the water! What did I do wrong if so?
