Mix together the water, lemon juice, and white vinegar in a small measuring cup or pitcher.
Carefully pour the mixture into a 16 or 20 ounce glass spray bottle. You may want to use a funnel, but you can also pour it via a measuring cup.
When you want to use the spray on produce, shake it up and apply a few sprays (enough to cover the skin) to your fruit or veggies. Let them sit for minute or two, and then wash with cold water.
Notes
This spray should not drastically affect the taste of produce, but it may slightly alter the taste of some veggies.
