A little goes a long way. But I usually mix 50/50 alcohol and water and then about 10 drops of oil per half a cup of cleaner. Feel free to add a little orange or geranium essential oil for a pleasant scent as long as enough lemon is added to cut through grease.
Mix all the ingredients together in a glass spray bottle or bowl
Spray cleaner (or dip rag) onto a hard surface
Wipe clean with a wet or dry rag
Notes
Feel free to swap out half of the isopropyl alcohol for olive oil or sweet almond oil to clean and polish wood or leather! When cleaning wood, some arborvitae essential oil can be very nourishing!
