if you put in your second valve first to double check your first felts and look into the third slide, you'll see the valve if it lining up or not without introducing anything into the horn.
In my shop, we use an ultrasonic machine WITH a mix of Dawn Ultra and a light acid. We used to do it with barrels of degreaser and acid solutions. The ultrasonic does a way better job, with half of the work. We just got the machine this summer and I've done 100-150 instruments so far. Much easier and faster.
I've been told by technicians who prefer the ultrasonic that the acid wears away too much on the brass of the horn and affects the tone much more than ultrasonic. What truth do you find to that?
Using Emery Tape is not a good solution for cleaning the tuning slides, it removes the metal as well as the plaque and causes air to leak, and slides to fall out on their own. It's better to use a brass scratch brush and soap.
Where do you get that cloth to clean the slides and and is there a way to do the chem cleaning at home or do you need to bring it to a shop to get it done?
Sarra Junior You can use a baking soda hot water bath to detarnish silver. Pour the mixture into a container lined with aluminum foil and submerge the instrument. Make sure as much foil is touching the horn as is reasonably possible and let sit for 15-20 minutes.
I have found that Ultra Sonic cleaning does not even come close to being as effective as the chem flush that is shown here. Having road tested the largest capacity ultra sonic cleaning machines I can say I was completely disappointed in the results of those expensive machines. Do whatever you want, but the cost of those machines is really high and the results marginal at best. Nice work.
That is nonsense. Acids do no eat away brass. That is false. If the shop is buffing or sanding the acid coloring off of the tuning slide tubes, that may remove material. However, there is a proper way to do that. That person probably just wants to hype up their ultrasonic.
I'm not buying any more 2nd hand wind instruments. Dental plaque 🤢 Bought a very old (100-150 yr) Eb clarinet (wood) the stench when I started to play it, same with an old Dolmetch alto recorder. Both had teeth marks on the mouthpieces 🤮 Nothing but new for me now! 🌸🎶
I use either Al Cass or Monster Oil in my shop. Blue Juice creates issues over time, as it's meant to also be a detergent, and isn't only meant to work with monel and stainless steel.
I totally agree with you on that one. To me, it has the consistency of water, it doesn't last and it smells like pesticide. It really gets to you when you breathe. I use Ultrapure synthetic oil for my valves now. Smooth as silk, lasts longer and free of odor.
Yes, I have kind of come to the conclusion that Blue Juice may be drying and leaving a residue on the pistons. The consistency is the same as Al Cass and pretty much all the others - water like. That is not unusual to me at all. As for the pesticide smell, the only one I have found that has a similar rancid kind of sent to my nose is the Holton/Bach oils. Certain ones. Really smelly to my nose. I have found that Hetman oil is a much better way to go. Finally if kids would use anything each time they played it would be a plus. If is the operative word there!
If Bluejuice gets too cold it separates into two materials, you can see what appears to be waxy solids floating in the oil. It also seems to stain the inside of the horn.
Love the way he tosses the parts of my $5000 trumpet around!
Glad you pulled the slide and let it fall on the floor. Really shows the level of care you have for that customers horn.
Andrew Eaton Like that? Yeah, that's why I have a nice rubber mat on the floor to protect anything that falls. No damage to date friend! :)

What solutions and chemicals do you use for the bright dipping process?
I cringed every time I hear the tuning slides clanging against each other.
I was hoping for “Carnival of Venice” at the end! ;-)
I liked the vid. Thank you. And I like "Blue Juice". I also "strap" brass slides like this guy.

What do you consider light acid to use with the dawn?
What acid did you use and for
How long?

I didn't get the "we should see a crescent" part on the valve alignment. Be nice to know what that is about.
His every movement was like fingernails on a chalkboard; this video nearly caused a nervous breakdown.
Where do you get that cloth to clean the slides and and is there a way to do the chem cleaning at home or do you need to bring it to a shop to get it done?
Very informative,, thanks much! I presume the acid in the chem flush is weak hydrochloric.
Lactic acid and Lauramine Oxide most likely --- I use CLR diluted with water
Did you leave out the part where you lubricate the threads of the bottom and top caps?
What kind of silver polish do you use
Hello, can you tell me what is the chemical that you used? thank you

how could i see that valve if the video quality is so low?
where are you located

Acid can cause red rot if not neutralised?

Blue Juice!!!
All cass is batter oil

Blue juice is certainly not a quality product - it's horrible stuff. I don't recommend it for student instruments, let alone professional ones!!

I use Berp bio oil. It seems to last forever.
Bro he said the valves are made of brass he doesn’t know crap. Would not trust him with my Bach strad.
He was talking about the valve ports actually, if you were paying attention. I thought that was obvious
