yeah...(repeating)
I never use this method on customer instruments...Since no one oils their instruments' interiors as generously nor as often as I do, customer instruments (when extensively cleaned) always need lime dissolved via the mild acid solution.

I don't see how interior coating is going to keep anything from getting filthy, and I'm not seeking disagreement. Everything in a house that's coated and everything in Industry that's coated gets dirty. Nickel brass and high copper brass mouthpipes don't rot when coated with lime, and a very large percentage of mouth pipes these days are fabricated of one or the other of these two alloys. It's really easy to dissolve lime scale with a mild acid. It's really easy to prevent hard lime deposits with frequent oiling with low-cost oil.
warning, double negative:
I don't think we can prevent people from not maintaining their equipment or not keeping it clean. I'm guilty about not mowing my property is often as I should. I probably should have re-oil stained the logs on the east side of my house this year, but it still doesn't look that bad, and I have been pretty busy. My bedroom needs vacuuming, my tuba room is messy. I'm sick, so I probably won't do either one of them this week. Etc. etc. etc.

You are disagreeing with yourself. I just would want to see a more permanent coating with a slick and harder surface.

I haven't time for trolls... too many people coming over expecting to eat too much food, and I'm exhausted from all the giggage yesterday. Merry Christmas.

Wow. Throw back time…

About 35 years ago, I knew this trumpet player who fancied himself an innovator (he actually fancied himself a lot of things…) and decided he was going to revolutionize brass instruments by coating the inside of his Bach C trumpet with some version of PTFE. (He had worked as a locksmith at one point.) He showed up in rehearsals with his newly treated trumpet and tried to get others to join him. To my knowledge, no one did…

He ended up trying to sell it to a youngster, but the valves moved like someone peanut-buttered them and it responded like it was made from lead with this really dull sound, so they passed. The trumpet player ended up unsoldering everything he could in hopes of salvaging some bits and pieces. He started showing up with some really funky frankentrumpets for a while before he bought something new.

I vote go for it.

Do it and show everyone how to execute their tubas.

I pulled the trigger and ordered one last night. Probably won't need it right away since I just got the CC back from the shop a couple weeks ago and the F is in currently (cleaning/regulation check).

German potato salad?
Does this tuba accept cookies?

Only when the content blocker is turned off.

Taking Bloke's suggestions for rigging up a hose, I ordered a few parts, including the hose, a spray nozzle with a thumb lever, and the necessary connecting bits. We have an old laundry sink in the basement that gets used almost exclusively for cleaning paint brushes. I lined it with towels, removed the main tuning slide, and proceeded to make the horn hot enough that it was uncomfortable to hold on to.

I think this worked well. Thanks for the suggestion.

My setup here is odd. Despite living in a fairly densely populated state, we are about as off-the-grid as you can be (well/septic/oil heat/propane gas for hot water and cooking). My basement is made of rocks, and the workshop I use for tuba stuff is an uninsulated 1880s structure with a wood stove, but we do have outdoor spigots. I’ve toyed with the idea of getting a propane-fired portable hot water heater for camping to do this kind of thing outside.

After 18 years, the 30 gal. water heater I put in my shop rusted out.

A friend sold me a little used 5 gallon BOSCH 110V water heater. ($25...great price for me...)

Cranked to max heat, it's ENOUGH to do a tuba and - if not - it's not very minutes until the NEXT 5 gallons is heated up in that tank and ready to go.

They're expensive if new!...
...but here is a used one just like mine:

...and here's an off-brand 4-gallon

Something else:

I did NOT pull 110 from the 220 circuit (formerly) dedicated to my 220v 30 gal...
I just plugged the 110 Bosch into the wall. It's been there for a good while...' hasn't popped the breaker once, and wires are not warm either.

bloke "For the record...I don't do any wiring...I just pretend that I do when posting...so all of this is theoretical...yeah, that's it: 'theoretical'... "

Heheh.

Hmm, rather redundant, isn’t it?

Anyone who's ever said "tuna fish sandwich" has no right to complain about "hot water heater"...

...and in fact, hot water heaters do heat hot water - except for the very first time they are turned on.

That was an unrealized quirk of speech I likely picked up from my dad. I’m sure I have some other Kentucky boonies-isms that I’m not aware of.

Anyway, thanks for the tips.
