No need for anything else other than good old water! We all sometimes forget that it isn’t soap that cleans us – it’s water! The soap is just there to break down the bonds which keep oil/dirt on the surface of things. It’s good old water that’s really doing the job and sometimes, all it needs is a little help from a gentle cleanser or helpful hands -
In studies at the Connecticut Agricultural Experiment Station in 2000, for example, scientists compared pesticide removal methods on 196 samples of lettuce, strawberries and tomatoes. Some were rinsed under tap water for a minute; others were treated with either a 1 percent solution of Palmolive or a fruit and vegetable wash. Tap water “significantly reduced” residues of 9 of 12 pesticides, and it worked as well as soap and wash products, the studies found.
Water temperature was not the key; friction was. “The mechanical action of rubbing the produce under tap water is likely responsible for removing pesticide residues,” scientists wrote.
For micro-organisms, try rinsing produce with a mild solution of vinegar, about 10 percent. In a 2003 study at the University of Florida, researchers tested disinfectants on strawberries contaminated with E. coli and other germs. They found the vinegar mixture reduced bacteria by 90 percent and viruses by about 95 percent.
