@Kehaulani said in Clean with 'alcohol'? I use Everclear. 95% Alcohol. I drink a big swig then play my horn. Kills everything in it. "Including brain cells."

Relevant to Kehaulani and his recent posts, that goes without saying.

Am I going to have to tolerate cheap, off-topic sniping like calling me brain-dead, going forward? This is like a playground bully who just has to have the last word, even though it's not even called for.

If we can't avoid finding opportunities to slip in cheap, crude shots, I may just reconsider my participation in this forum.

Listen to you own advise. You have been doing that too me routinely the past week. Read those posts that you haven't deleted, as many of your snipes have been deleted. The proof is evident all throughout you posts attacking me so, take you own advice and Please GET OVER IT so threads can move forward without your continued disruption. I hope you personal situation improves as you are going off the rails. OK.

@Dr-GO
Thanks for clarification and advice. I defer to your expertise and accept spores are resistant to ethanol. Regarding single cell organisms, I am told (by other medical authority) ethanol will kill many, such as:
Pseudomonas aeruginosa
Serratia marcescens
E. coli
Salmonella typhosa
Staphylococcus aureus
Streptococcus pyogenes.
Would you concur?
If true, then I think I shall continue to use ethanol to inter alia avoid contracting the above. I do give my horn a soap bath and rinse regularly, too.

• best regards,

True but these do not make spores. Those making spores are mycobacteria. It is the mycobacteria that cause more interstitial lung disease.

Opinions?

I prefer Ethanol, for a few reasons: not toxic; acts instantly against spores; is hygroscopic; very low cost. I pour about 5ml into the mouthpiece and blow it through the horn, daily at the end of each session. I then leave it in the horn to absorb water off the metal and act as a reservoir for disinfectant. Over-night, the alcohol will have evaporated significantly to a low concentration. Commencing each session, I blow the condensed liquid out of the horn via the water keys, then oil the valves. All is very safe to humans.

Once again, this has not been medically proven. A clean smell may result but cultures still grow spore related organisms and fungus (2010 September Issue of the journal, Chest)

Opinions?

I found a reference to ‘alcohol’ in a thread about covid:
https://trumpetboards.com/topic/617/covid-19-closing-down-music-venues/47

Toxicity. Propanol is more toxic than Ethanol. Additionally, rubbing alcohol will have poisonous additives to ‘denature’ the alcohol. Thus, as a disinfectant for instruments, Propanol should be rinsed away with water, preferably distilled and de-mineralised water.

Isopropyl alcohol is highly volatile so will not linger past several minutes, however a water rinse will clean away any residual.

This actually has been studied in the medical literature. Ethanol does not eliminate difficult to remove organisms (virusus or those causing spores). For virus bleach does work but YOU DO NOT WANT TO GET BLEACH ON BRASS WITH SILVER PLATING. ONLY isolpropyl alcohol at 91% (Woods alcohol at 70% did not do as well) was shown to eliminate resistant organisms.

@administrator said in Covid-19 Closing Down Music Venues:

I have never poured isopropyl alcohol down my instruments. I bet they'd stink for weeks!

No odor. Isopropyl alcohol is highly volatile and the odor is gone under a minute. I use a glass container (with a cap) to soak slides and valves for about 15 minutes and then quick pour through the bell and leadpipe tubing and rotate the horn until it drains out the outer end in a collection bucket.

@administrator said in Covid-19 Closing Down Music Venues:

I'm not a metallurgist, but I remember learning somewhere in my music school studies that brass does have certain anti-microbial properties.

https://en.wikipedia.org/wiki/Antimicrobial_copper-alloy_touch_surfaces#:~:text=The surfaces of copper and,a high degree of efficiency.

Brass does, but not to bacteria that form spores or viruses. Isopropyl alcohol at 91% has been proven (in the medical literature) to eliminate these additional pathogens and recommend to re-use every 1-3 months to maintain control of these pathogens.

More proof of brass safety. Even a trombone does not have enough bell discharge to "bolero" out a candle...

...sulphur ...a natural ingredient of crude oil.

Which would explain why the call it crude.

@Kehaulani said in Opinions on Valve Oils?:

Seems to me that the O is a novice so thorough orientation might be in order.

Orientation on how to oil valves? Do you compulsively take apart your trumpet every week to clean out the casings, run cloth through the pistons, then oil... from what the video shows as a 5 minute process? The quick wipe down that Mike and I use (Rowuk as well) takes under a minute. Seems to me that the K has a compulsion and a visit to his psychologist might be in order.

@IrishTrumpeter said in Opinions on Valve Oils?:

Hey Dr Go - would you have a link/description of the Valve wipedown technique?

The video above is for a compulsive cleaning. With weekly oiling, I skip all but the wipe down of the pistons. That I always do, and will also clear away all of the biofilm on the rim of the valve bore.

re locked sticky; Jens & Mouthpieces Sticky (Your MPC is TOO BIG!)
...a 3C can give a well-balanced result for tone, range, flexibility. But a 3C will not give the same tone as a 1.5C: if it does, the issue is the player. In my case, a 1.5C definitely gives a bigger, fuller, sweeter, greater dynamics than a 3C. With a 1.5C, I have no trouble to fill a concert hall with a 'teutonic' sound. I think pros should strive for 'the sound', and this means working hard to develop the chops needed to perform on a mouthpiece larger than a 3C. imho, the 1.5C is the pro standard to achieve, with larger being a matter of individual strength.

opinions?

I detailed more specifics above, I believe there is much truth in your statement. As I noted above I graduated from a 10.5 C to a 3C and to most degree, experienced the same performance results you achieved. Have not made it to the 1.5C yet, but I have made proportionally some rater aggressive leaps and bonds with some amazing success as well.

Did you have to search for that emoji ?

...Doc is a brash kinda guy so I feel this horn suits him...LOL !

In my youth, my mother would always tell me I was full of piss and vinegar, but brash works as well.

The only problem is, I am now an old man with prostate issues for which I am taking apple cider vinegar three times a day to help relieve, so how my ignorance of my past youth, and my mother's predilection, has come back to haunt me at this time.
