To clean zucchini use cold running water and rub its surface with your hands; the skin of the zucchini is very thin and delicate, so do not use any scrubbers or vegetable brushes to clean it. Once all of the dirt, such as soil, has been removed, pat the zucchini dry with a towel. To use the zucchini in a recipe, simply cut the top and bottom of the zucchini and toss, then slice as required.
