What should I do if there is salt crystallization in the glass nozzle of the salt sprayer? Is the glass nozzle or other operations not done well?

There are several reasons for this: 1. There is something wrong with the nozzle itself, which is not precise enough, especially a kind of inclined nozzle is easy to crystallize. 2. The purity of sodium chloride used is not enough, and there are many dregs. 3. The spray pressure is too small to be completely atomized. 4. Spray compressed air contains too much oil, and the air compressor should drain water frequently.
