Clean Boat Propellers
After cleaning the propellers with CleanEz coat them with Teflon to keep the mold and grime off the blades. Make sure the Teflon you use does not contain petroleum distillates, which is sometimes called Aliphatic Hydrocarbon, Mineral Oil or Hydrocarbon on packages.
The polymers in Mary's Advantage also make a surface slick and work quite well on propellers. Plus it does a great job shining and protecting your boat.
