How to control the humidity between 45% -55% during guitar maintenance?

I'll give you the simplest and most straightforward guitar humidity control method to ensure stability at 45% -55%, without any mysticism or fuss.

1、 First, buy a small thing: a hygrometer

A dozen yuan, put it in the piano bag/case, and you can tell whether to humidify/dehumidify at a glance.

2、 The most stable solution: keep it in the piano case for maintenance

Guitar case is the easiest to control humidity and is 10 times more stable than placing it outside.

1. Too dry (humidity<40%) → humidified

Use guitar specific humidifier (sound hole humidifier/piano case humidifier stick)

After adding water, put it into the piano case and close it tightly

Check the humidity once every 1-2 days and take it out when it reaches around 50%

Suitable for: Northern regions, winter heating, and air-conditioned rooms.

2. Too humid (humidity>60%) → dehumidification

Guitar specific dehumidification bag/silicone desiccant

Just throw it into the piano case and replace it if it's trendy

Remove or pause when the humidity drops to 50%

Suitable for: Southern regions, rainy season, coastal areas.

3、 How to control the humidity in the room (without putting the piano case)?

Keep away from: heating, air conditioning vents, direct sunlight, window edges, bathroom, kitchen

The room is too dry: turn on the humidifier to maintain the room humidity at 45-55%

The room is too damp: turn off the dehumidifier/air conditioning dehumidification mode

4、 The simplest daily operation (just follow it)

Finished playing → Clean the strings and piano → Put back the piano box

Put a hygrometer in the piano case

Dry humidification, wet dehumidification

Maintaining 45% -55% is the safest

This way, the neck of the qin will not deform, the product will not be damaged, the panel will not bulge, and the glue will not peel.

5、 You just need to remember three sentences

Humidification is required below 40%

If it exceeds 60%, dehumidification is required

45-55% is the safest
