Hypochlorous acid is faster and more effective at killing bacteria and spores than bleach! Seriously, look it up. It's also safer for your skin and lungs (your body actually produces this chemical in small amounts).
 
Saves money.. and plastic waste.
 
Just add 7 grams of pure/kosher salt and 1/4 teaspoon white vinegar per 250ml of distilled water
 
Fun fact: did you know that bleach water is only effective for 24 hours?
