I too use a homemade recipe
Stir 1 -2 teaspoons of cornstarch into a bit of cool water to dissolve
Stir in 1 cup boiling water, and stir for one minute to fully dissolve cornstarch
stir in 1 cup cool water.
let sit until cool enough to handle and pour into a spritzer bottle.
That's it! All natural, made for pennies, super easy and friendly to you and the environment.
You can add some lemon juice (2 teaspoons) if you like, but it's not necessary. Shake well before each use and throw away any you don't use within a week. No preservatives means it doesn't last as long as the commercial stuff, but given that it is so inexpensive and easy to make, this is not a problem.
