<<Disclaimer: Verify this information before applying it to your situation.>> I have contacted Earth Friendly Products about their fruit and vegetable wash, available in most health food stores: We have spoken to our suppliers and they indicate that our citric acid is gluten free. They are forwarding us a letter confirming this too. Thanks again for being a concerned consumer.

Most contain citric acid of some sort. Steve
