I use liquid germall plus, but some are not comfortable using that in anything that is sprayed (I feel it only applies to anything aerosol-ized), but any water soluble preservative will be fine.
I mix Lavender with distilled water to use as a spray. It does not come in contact with other water.
Do I need to use a preservative in this?
