Old York Cornet Restoration #7: Chem Clean and Polish

[@McJays]

Hi. Great job on the cornet. We all want to know what are the chemicals you're using for the descaling and the silver cleaning?! Please! :))

[@beru58]

You know that you will never be able to sell that one for the value of the work you put into it. Right or? But you are doing an amazing pedagogical effort. Most likely learning, expanding and honing your skills on the way. We your "students" are most grateful. I live in Sweden so when I need somthing done to my horns I will turn to someone closer by naturally. Had I lived reasonably close to you, yours would be the shop of choice for sure had I been in need.

At the first video about this instrument, you said this cornet wasn't worth repairing. And it may not exactly have been, dollar for dollar, depending on what you value your time at and what you can sell it for. Im really glad you chose to do this restoration though, it has been worth it for me as a viewer. Cant wait to see and hear it finished

This was fascinating! Thank you so much for this series on the cornet.

[@timmoen1083]

The bell detail is beautiful. I hope to see some good close ups of that in the next video! Thanks for not abandoning this cornet and taking me up on the challenge! I’m still surprised that you’re doing it but it seems like you get more subscribers every week when I check out your channel, so keep goin. Can’t wait for the herald trumpet!

Hi! What kind of chemicals you use for cleaning trumpet inside? Thanks.

[@jp554731]

Where can you get the chemical and the pink liquid silver dip?

[@niav7612]

Thank you, this series is so interesting!

[@HighMansx]

@2:45, that looks perfectly normal to me...

[@1090yoyo]

This series is fascinating ! I'm currently trying similar work on an old belgian baritone. But since i'm in Europe I can't order liquids from Ferree's they are not shipped overseas. Do you have any idea of the composition, or a recipe to make it ? I guess there are some acids but I guess you've to pick the good one...

[@McJays]

For descaling, you can use a solution of citric acid. I've found that a concentration of 30g of lemon salt to 1L of water works wonders. Currently, until I finish my ultrasonic cleaning tank, I'm using a plastic 220L barrel for this exact purpose. You can also use acetic acid-based products, like Essigreiniger in the german Lidls. Works wonders in maybe 6-10 hours of soaking for the really old crudd!

[@1090yoyo]

Thanks ! I'll get some citric acid then, it's pretty cheap in powder (is that what you call lemon salt ? Sorry for the question I'm not english native)

[@Tuca-Luthier.]

@@1090yoyo Good morning friend, did you get the answers to the solution, for Brazil it cannot be sent either, could you help me?

[@viktorartamonov1844]

As an alternative to wick for a kerosene lamp, can I use keeper tape?

[@jayl7890]

Great Video. You mentioned using vinegar as a substitute. Would you dilute the vinegar, when using it on a horn ? Also, is vinegar safe for Silver?

[@davemiller7633]

Wondering...if you use the silver dip on non silver plated instruments will it enhance the effect of the regular chem dip?

[@Laxpowertoo]

What chemicals do you use in your first soak, and what sort of concentration?

[@matthewkinczel2774]

If you end up polishing it, why do you even put the horn in the silver dip?

[@TheBrassandWoodwindShop]

I only put it in the silver dip when it is very tarnished. the dip gets off a lot of the tarnish, but not all of it. The manual polishing would take a very long time on very tarnished instruments. Also, this cornet was satin silver which is harder to polish by hand.

[@kennethnolan6578]

I have seen on some other websites that Trumpet players will chem clean there trumpets with Lemon juice or distilled white vinegar. Should cleaning with white vinegar or lemon be avoided?

[@TheBrassandWoodwindShop]

I have never used lemon juice, but it is probably fine. I would just be careful not to put lacquered surfaces in any acidic liquid too often.

[@adriangarcia7839]

What type of metal do you use for the hook? would any type of metal work (due to the chemicals)?

[@TheBrassandWoodwindShop]

The hook is made from a 1/8 inch brass rod.

Hello, I'm watching your video, but unfortunately I don't understand English very well. Please plant, what kind of liquid did you swirl the cornet in?

[@TheBrassandWoodwindShop]

It is phosphoric acid and silver dip. Unfortunately, they do not send it outside the USA. What country are you from? Maybe someone from your country may know where to get them.

@@TheBrassandWoodwindShop Thank you so much  Проверено

[@jayl7890]

What would your recommendation be to polish gold plated instruments?

[@TheBrassandWoodwindShop]

Silver polish will work, just do not polish it too vigorously because gold plating is very thin. Gold plated instruments do not need to be polished very often because gold does not tarnish very easily.
