Get Rid of Powdery Mildew on Plants

Here are some instructions on a recipe for a solution to remove powdery mildew from a plant and prevent it from growing back.

Steps

Mix one tablespoon baking soda with one gallon of near-room temperature water.
Add one or two drops of liquid soap to help the solution adhere to the plant.
Add a teaspoon of vegetable oil (olive, sunflower etc.) and shake well to create an emulsion that will help contain the spores (and limit re-infection of the plant).
Spray the affected areas with the solution.
Repeat as necessary.
Understand why this works. This solution changes the pH balance on the surface of the plant, making it an unsuitable environment for powdery mildew to proliferate.

To make in smaller "doses", mix 1/2 tbsp of baking soda with {{safesubst:#invoke:convert|convert}} of near room temperature water. Add 1 or 2 drops of standard liquid soap. Try to get soap without any added lotions or that "Keeps hands soft", as these don't change the Ph as much as standard soaps do.

Do not eat baking soda unless completely dissolved. Undissolved baking soda is known to cause major stomach problems. More about this and daily doses should be located on your current baking soda box.
