Rubbing a little baking-soda on each lens cleans heavy deposits. After rinsing the contact lenses can be applied immediately to the eyes. Another remedy I tried using is rubbing toothpaste on each contact lens. But after rinsing you need to store them in Saline Solution over night. If you try to put them in your eyes after cleaning with toothpaste, your eyes will get irritated from the peppermint. Learned from experience.
