If the numbers on the fruit tag is 90000 series they do not spray anything. Lot of people say organic, but it may not be. It also has USDA organic stamp on it. If you have the brand name, google it and see the company policy.
What I do is soak all my fruits in warm water with five drops or 32% h2o2, leave it in for five minutes, it will remove anything on the top layer.
