Maintenance may not be at the top of your mind as a harmonica player but it is something we all have to deal with. I bet that at least once you have experienced a stuck reed in one of your harp. Quite likely the reed was stuck either by a foreign object that came with your saliva. Sugar residue can also build up if your mouth is not clean when you play. In this article I will give you a few pointers on how to keep your harmonicas clean enough to avoid these mishaps.
The first thing you should do is make sure that your mouth is as clean as possible before you start playing. What does not come into your harmonica will not have to be cleaned out. The best process is of course to always brush your teeth before playing. Although most people understand this, it is not always practical or feasible. Some people will flat out ignore this advice. I have to admit that I don’t always do this myself unfortunately. The second best thing you can do is to rinse your mouth with water before playing. I try to keep this as my minimum standard and it works quite well. Even if you don’t brush your teeth or rinse your mouth with water there are a few things you can keep in mind, especially during a jam session.
- Don’t eat peanuts or chips/crips during a jam session, gig or practice session
- Don’t drink sugary beverages
- Drink water
When you have finished playing, don´t forget to tap the harmonica lightly to remove any moisture. To keep moisture build up to a minimum I have found that warming the harmonica in your hand before playing helps.
All of the above will help make sure that foreign objects don’t make it into your harps.
Even with the best preparations and intentions once in a while your will end up with a harmonica in need of some maintenance. The first thing you may notice is build-up of crud in the holes. See picture below.
To handle this I recommed tootpicks, gap toothbrush or a reed lifter tool. It is very easy to gently clean off the crud from the harmonica.
Cleaning like this will keep your harmonica in good order for quite some time. If a reed seem to get stuck you can use a tooth pick or the reed lifter tool to gently put it in motion. If these actions don’t do the trick you may have to do some more cleaning.
Cleaning a disassembled harmonica
When you take a harmonica apart you get a whole lot more options for cleaning. Most likely you will find that both the reed plate and the comb are dirty.
The first step to cleaning here is to use a soft toothbursh. Make sure you are not pressing too hard and brush in alignment with the reeds. You can also use water or some form of mild cleaning fluid on the reed plate. Make sure to wash it off before assemblying the harmonica. Do not use a lot of water on an unsealed wooden comb, the wood will absorb the water. If you are unlucky the wood will swell and warp. Id you have a plastic comb you can use a whole lot more water to clean it.
You might wonder why so much dirt make it in between the reed plate and the comb. It can di so because the reed plate and the comb are not 100% flat so there will be voids. If you buy a high end custom harmonica this will be less of a problem. These harmonicas have a tighter seal because of the flatness of the comb and reed plate. It will however not completely eliminate the problem.
Heavy duty cleaning
To get everything completely clean you need some more heavy duty equipment. I use a ultrasonic cleaner to clean reed plates, cover plates and screws. I do not recommend ultrasonic cleaning for wooden combs. The cleaner uses high frequency vibrations to basically shake the dirt off. It is very effective and can get everything more or less completely clean.
To make the cleaning even more effective I would recommend a cleaning liquid such as the EM-070 or similar which is normally used to clean dentures. Just make sure to clean it off with water after the ultrasonic cleaning.
As you can see there are many levels to maintenance and doesn’t have to be a bother. With a few tools you can come a long way. Let me know if you have any questions and don’t forget to sign up for the newsletter below.
I would recommend adding another step into your excellent explained maintenance step. That is to end the wooden comb cleaning process by flat grin the surfaces on emery paper, I.e 600 gritted and finally oil the surfaces with either bees wax. Apply a thin layer, let it stay for an hour or so before wiping it off with a soft cotton cloth.
This prevent moisture from affecting the comb and it will not warp or become uneven for a long time.
Thanks for your professionalism explaining and sharing your knowledge.
Glad you liked it. Excellent suggestion on keeping the comb from warping.
