8-10dropsessential oil of choice(optional. Lemon, orange, or another citrus would be my choice here, but lavender or others would be nice as well. Go here to learn why I chose this company as having the best essential oils for the money.)
Combine everything in a spray bottle. (You can reuse the container you already have from your store bought glass cleaner. I had to buy one at a dollar store since we haven't used glass cleaner in years :-)!)
Shake well to mix.
Spray onto glass surface and wipe clean.
Do not use this glass cleaner on marble or coated eyeglass lenses.
