I use Dr.Bronners liquid soap. I put some water in a spray bottle, then a bit of soap, close it and shake the bottle to get it foamy. I put the fruits or veggies in a collander in the sink, and spray the soap over them. I turn the produce around, and spray again. Then i open the bottle, and pour out the leftover soap over the produce. Then i rinse or brush (plastic veggie brush) the produce under the faucet. I usually use the peppermint or tea-tree ones for washing produce. I also use this soap for a lot of other things.
