What is your rinsing procedure prior to playing ?
I'm unsure if you're talking about your mouth or the chromatic? If the former, I just experienced 'that' kind of problem yesterday at the Long Island harmonica club's dinner. The meal is served AS people are going up to play--a bit of a quandary. I'd already put my name on the sign-up sheet (which
proved to be a mistake later on since it forced me to stay on edge throughout the entire meal, grabbing tiny bites while player after player went up and
I continued to sip a glass of wine, then water (I usually drink copious amounts of water before playing under any circumstances)...the wine was out of the ordinary for me--since I rarely ever indulge - but hoped it might relax me sufficiently to deal with my inevitable case of 'stage-fright' or what passes for it....but somehow my name wasn't called until the entire meal was finished (including dessert with coffee which I avoided). Turns out the guy holding the list had no idea who 'scotty' was so simply skipped me.
By then my nerves were so frazzled and I'd already paid at least 3 visits to the ladies' room, lolol. What made it worse was I now had an entirely captive audience with nothing to distract them: ALL eyes focused on me (ulp). So, on my last quick run to the bathroom I quickly rinsed my mouth (and I do carry a small portable toothbrush so did a quick once over sans toothpaste, but good enough methinks. My chromatics are kept clean before I leave the house and I always wipe them down in between playing with a dampened microfiber cloth. THIS time, one of my fantastic and good harmonica friends --who happens also to be a SlideMeister (Ed) --gave me a handwarmer I hadn't tried before. A 'grabber'. He already had it out and warmed up--it was incredible. Already far warmer than the 'hottie hand warmers' I'd bought a big box of years ago--and far more effective. I slipped it into my cx-12 cloth case in this very chilly restaurant so by the time I got up to play, the chromatic was toasty warm (I likewise tried it with my Super 64 and it also warmed it up sufficiently to play, but then the CX-12 got cold so I switched back). Quite incredible--I'm definitely going to buy a box of those (Thanks, Ed!) Anyway --while my performance (of two blended 'Americana' songs: Shenandoah and 'Do Not Forsake Me Oh My Darling'--otherwise known as the theme from High Noon) wasn't remotely up to the standard I'd set for myself (I kept running out of air as I'm wont to do in these kinds of situations while this does NOT happen at home or in casual, relaxed playing with friends), I got quite a few one-on-one sincere compliments from people who DO know something about music and melody. John Savas (already in his 90's and still playing fantastically well), told me that he was very impressed with what and how I'd played and that it usually 'takes years' to be able to do what I'd done. I wondered if I'd dare tell him I'd played as a kid then took a long hiatus, but decided to leave that be. He loved the song choice. His friend (whose name I didn't get), told me that I had beautiful tone and he loved the blend of the two songs...was impressed by my using an A chromatic (when I 'fessed up to that). Both then said that 'A is a lovely key of chromatic' so even these classical/playing men aren't averse to 'other keys'..good to know. Afterwards, as people were getting ready to leave, John and I talked about how many hours of work he'd put into the 'cheap Huang' he'd used to play some patriotic songs (for veterans' day) the last time he'd gone up to the mic--comparing it to the cx-12's ease of disassembly I'd just shown him (he does have other chromatics, of course). He was amazed though, and very impressed with the cx-12, especially the single piece slide and that one plays the shell itself and just how easy it is to keep clean and wipe down just before play - and after, remarking on how spotless mine was right after my performance. No 'fiddly bits' of a mouthpiece to have to work on to ensure all parts function together. 'Rinsing' is good if you don't have access to a bathroom, hahaha--but simply drinking a lot of plain water has worked for me for years.
