Give the tuner a good wash in Dawn and hot water. Then set tuner in a plastic container and cover with vinegar let soak until rust is gone may need to have a old tooth brush handy. Then mix baking soda and water together lots of baking soda. Place tuner in solution for 10 minutes and then rinse and dry. hair dryer works wonders. Spray with something of your choice to prevent rerusting. Like WD 40 or a clear coat.
