Vinegar is amazing..... take the worst rusted piece of metal you can find, let it soak in apple cider vinegar for 24hrs and you will be amazed at how clean the parts come out.
Soak all your produce in a sink full of water and 1 cup of vinegar, apple cider or white and they'll be super clean and ready to eat in an 15 mins.
