Soak In Salt Water Solution
One of the best and simplest of them is a simple saltwater soak. Combine 1-2 teaspoons of salt and a large bowl of water and steep the fruits in the mixture for 10-15 minutes. The salt is used to loosen the dirt and insects and some detritus left behind by pesticides. When soaked, rinse in a lot of running water to get any of the salt and dirt out. The method is particularly effective with grapes, since the solution can access between the clusters.
