What do you think about this?
I’ve got a crossover.
Youtube says it’s cool, but chat gpt says it’s a bad idea as it can damage the comb and the reeds. And using it more than once a month is crazy.
I don’t know 
Thank you!

I got give one for christmas and use it on them once a month or so in addtion to regually giving them a rinse with warm water. it doesn’t seem to harm them at all and I assume it is actually setilising them.
I’m just not sure how essential it is as regualr rise it with water seems to do just fine. I doubt it’ll hurt it unless you’re obsessivly puttung it in every single time you play, which seems overkill.

You’re using water with the wood comb? I heard we should only do it with plastic ones or the wood could expand.
Thank you, Piglet!!
Arh, all my harmonics have plastic combs. I’m sure others can advise better than me on wood combs, but would’ve thought a quick rinse and then plenty of drying time wouldn’t be too bad (although I could be wrong on that)

Hohner say the comb on the crossover is completely sealed, so you shouldn’t have to worry about moisture.

Thank you, Piglet!
But I’m not quite sure it’s good to put it under the water
You should be fine, the wood is sealed up with waterproof stuff. We’re talking about rinsing warm water though it to wash the spit and other gunk out not soaking it for extended time. In yey olde days of time gone by the combs didn’t used to be well sealed so water could make them swell but you should be fine with your crossover.

I remember as a kid in chichago watching the old harp guys on maxwell street. They would soak the harps in water to expand the wood on purpose. Not sure why but they would have several harps soaking in A glass of water. They would switch every few songs. Again not sure why?

I can imagine several possible reasons that they regularly swtched harps:
(1) They switched to a different key.
(2) When the harp has been in the water for a while the wood comb soaked up some water and expanded. This possibly made the harp more efficient (more air-tight). After playing it for a while the comb contracted somewhat as it began to dry and the efficiency of the harp was decreased. So they switched to another “fresh” harp with a soaked and expanded comb.
(3) Perhaps the reeds in the harp began sticking as sticky saliva began to build up on the reeds, so they changed to another “clean” harp and placed the “dirty” one into the water to dissolve the crud while they played further on the “clean” harp.

I’ve seen people soak harps like that, but in beer. Wondered why but never asked. Wouldn’t have thought beer would be good for the harp, but maybe for the players🤣

Good topic. In order to keep cheeseburger and fried chikin chunks off my reeds my habit is brush, floss, and rinse mouth. After playing rinse harps (all plastic combs) in warm water as mentioned, dry overnight. That’s it. However…., There is a thing called “biofilm” that attaches to the reeds whether I can see it or not, so they go into the ultrasonic cleaner ever few months. Play better, sound better, last longer, but I may be wrong about some, part or all of this. But I’ve learned alot hanging out on these forums over the years.

@pabloterraga If Seydel says it’s fine for their 1847 Classic, then it should be fine for Crossover too.
BTW the Crossover does have one coat of lacquer on all the wood, but it’s 3ple coated only on the face of the comb.

@pabloterraga Who is chat gpt?
What’s your problem, @pwherda ?
pabloterraga,
Why such a curt response to my question!! Obviously it’s certainly your prerogative not to answer my question, but I can’t comprehend the reasoning for such a response as I can’t see anything in my question that could in any way possibly be perceived as rude, and or whatever way you took my question to be.
I’m 79 and not really all that much up on the plethora of various Web sites, much less any of the social media sites. I simply by chance ran across the Seydel disinfection bag and was curious about its perceived effectiveness and with that I did a research on Google, YouTube, etc., and then of course here on this forum site and came across this thread on the subject and your reference to chat gpt. Maybe I should have asked what chat gpt is as I had no idea if perhaps it was the username of a member here, an acronym for something or perhaps the name of some Web site? Bottom line: I honestly have absolutely NO idea whatsoever who, and or what chat gpt is! Other than that just a suggestion from this ‘ol guy, but perhaps being a tad more patient and showing some understanding to other members questions might not be such a bad idea. But, like said…… just a suggestion.

I’m sorry.
I completely misunderstood your sentence. I thought you were teasing me or messing with me and telling me to search over chat gpt instead of asking here, that’s why I asked you what’s your problem, as I understood you were being rude.
I’m so sorry, friend. A big hug from Spain and almost merry christmas.
Sorry again, friend.

Hello, chat gpt is an AI platform you ask questions to and it will research the internet for the correct answers. It’s like an Alexia device but on your phone. “Chat GPT” is the name of that particular app. There is siri, and Gemini etc… they are doing more and more! My nephew uses it for his college assignments! It’s crazy! Hope this helps. And as far as disinfecting your harps, I use 1 part mouthwash to 2 parts warm water, soak for a few minutes then wipe and air dry. Hope this helps!
Not a problem. No harm, no foul done. The comment simply took me by surprise and obvious puzzlement. At my age and having Uncle Sam trying to kill me back in ’67 and having fought with pancreatic cancer for the past 3 years have left me with a rather thick skin. .
