Allow alcohol to be used for substrate flux washing etc.
The red lid and the white part are resin, but the other is metal, so it is strong for solvent type.
Maintenance will be better if you disassemble and clean up if the metal balls get dirty and discharge will not go wrong.

I bought thinner to degrease parts after processing and so on. After we received the item, I tried to push the pump several times, but the thing I bought is bad and I may not come back. As the parts inside the pump did not slide smoothly, I felt the movement was astringent, so disassemble the pump part by removing the screw tightening the plastic cap base part. The structure inside is simple, one Φ 3 metal ball and one spring come out. Attention is needed for loss. Sure enough, since the surface of the brass parts was slightly rusted, after lightly polishing with waterproof paper, it was mirror-finished with buffing and it was reassembled and used,

Add absolute ethanol and use it for cleaning. It prevents volatilization, and only a small amount comes out when I want to use it and it is saved.
