Because I have a decent collection of essential oils, sometimes I realize I can make certain cleaning products at home instead of buying them. I use similar oils in my vinegar based kitchen cleaner, so if you have to purchase oils it might be helpful to buy ones you think you'll use twice!
1. Add 1 Tablespoon of rubbing alcohol to a small spray bottle.
2. Add 5-10 drops of lemon, lemongrass and bergamot essential oils (or substitute for other scent of your choice!)
3. Fill the bottle to the top with water (preferably distilled but I often just use filtered).
4. Mix, label and spray away!
As always, let me know if you discover better scents or tips! I've heard adding a drop of castille soap such as Dr. Bronner's helps to cover the toilet bowl better but I have yet to try. Hopefully you find something simple that works for you!
