my mom does this-Cleaning fruit - fill sink with water, add 1 C. vinegar, mix. Add all fruit and soak for 10 minutes. Water will be dirty and fruit will sparkle with no wax or dirty film. Great for Berries too--keeps them from molding. I do this with strawberries and they last for weeks!
When buying fruit and veggies, always soak them in a 1:4 ratio of vinegar and water to help remove toxins and pesticides. Leave them soaking for up to an hour, longer with nonorganic apples. At the end of the bath, sometimes you can even see cloudy like stuff in the water from the skins and waxes, and dirt on the bottom. Works awesome! Once I did this to blackberries and they were good for 3 WEEKS! Thats unheard of with berries water. The vinegar is KEY :)
