I was sick of dishing out 3-4 bucks every month to buy a new "spray cleaner". So, I made some out of things I had in my kitchen. It works really well, and involves no bizarre chemicals. Technically, you could bathe in it with no harsh side effects. Except you might smell funny.
a few drops of lemon oil (or any other essential oil you like)Lavender? patchouli?
juice lemons and thouroghly remove pulp by draining in cheesecloth. Boil the lemon juice mxed with water for a few minutes. Add an equal measure of white vinegar (or less if the smell bothers you). Add the essential oil. Allow to cool and pour into the rinsed out spray bottle from your old kitchen spray. Clean stuff.
