How long can you store it before it starts to go bad or loss it effectiveness?

There is nothing on the product package that suggests a finite shelf-life.

An this be used with a electrostatic sprayer?

If it produces a fine mist or fog it can be used.

Is it safe on metal? I have a dehumidifier under house, is it safe on unit?

It says its safe for use on construction materials but I'd protect the electronic components of your humidifier
