A 10% salt solution appears to work as good or better than full-strength vinegar for washing fruit and vegetables
When plain water was tried against a half dozen other pesticides, less than half the residues were removed.
What about diluted vinegar? Diluted vinegar only seemed marginally better than tap water for removing pesticide residues. Using full strength vinegar would get expensive, though. Thankfully there’s something cheaper that works even better: salt water.
A 10% salt solution appears to work as good or better than full-strength vinegar. To make a 10% salt solution, you just have to mix up about one-part salt to nine-parts water (though make sure to rinse all of the salt off before eating!).
