How to Restore Harmonica Reeds

Introduction

In the event that a note in your harmonica has become unplayable, it's very likely that the reed has become misaligned and needs to be restored to its proper position.

Within this guide, you will be able to take apart your harmonica, clean the reeds, and finally warp the troubled reed back in place.

In addition to the listed tools, certain items will also be required such as a bowl to hold water and vinegar, a small soft brush, and a flat implement such as a knife.

Remove the 8mm Phillips #1 screws on each end of the Harmonica holding the cover plates in place and set these aside.
The screws come in pairs so make sure that 4 screws are recovered.
Set aside both the top and bottom cover plates

Step 2

Using the Phillips head screwdriver, remove the 11 mm Phillips #1 screws in the center of the Harmonica holding the reed plates in place and set these aside.
Separate the reed plates from the comb and set the comb aside.
Note the orientation of the reeds and which direction they face as you you set them aside. Referencing how they align with the comb will also be helpful when putting everything back together.

Step 3

In a bowl large enough to fit both reed plates, fill with water and a few drops of vinegar.
Place and leave the reed plates in the solution for 30 minutes.
This, and the following step, will serve to ensure the reeds are clear of debris for the fix and to keep your harmonica hygienic for safe operation.

Step 4

Remove the reed plates from the solution and use a soft brush to clear away debris.
When brushing reeds, it is important to brush in an up and down motion following the direction of the reeds. Failing to do so could cause unnecessary damage to the reeds.
Rinse the plates and allow them to dry.

Step 5

With the reeds on the reed plate facing upward, use a thin implement (such as a knife) to prop up the warped reed.
Use the flat head screwdriver to gently bend the reed into uniformity.
This process can take time and requires patience in order to keep the reeds from further damage.
The end product should be a roughly straight reed that just barely hovers over the cavity below.

Step 6

Place the reed plates back onto the comb and use the 8mm Phillips #1 screws to fasten them in place.
Do the same with the cover plates (the numbers on the plates should be in line with the holes) using the 11mm Phillips #1 screws.
