There are fifteen produce that show little signs of pesticides after being washed.  I personally try to purchase as many items as possible organically, but in a budget crunch I will buy items on the clean fifteen lists.

1. Onions
2. Avocado
3. Sweet corn
4. Pineapple
5. Mangoes
6. Sweet peas
7. Asparagus
8. Kiwi
9. Cabbage
10. Eggplant
11. Cantaloupe
12. Watermelon
13. Grapefruit
14. Sweet potato
15. Honeydew melon

When beginning to switch to organic produce, this is a great list to follow to help with the budget!  The clean 15 list allows you to save money for the items needed on the dirty dozen lists!
