This is the 13” Replacement for your 100% Pure Lambswool Mary Moppins Wash Pad. Recommended and used by Tiffin and Newmar Motorhomes, along with other Boat and Auto detailers, this 13” pad is made from genuine 100% Lambswool with REAL leather backing. It will gently wash your RV, Boat, Airplane, Car or Truck without scratching the surface, unlike a brush or microfiber. Use with your 13" 4-Way Swivel Pad Holder, or purchase the Mary Moppins 13" Wash and Pad Holder. Wash without fear of scratching your finish. This pad will lie flat to clean roofs, and will swivel to reach around curves. Turn the Lambswool lengthwise and work left to right. Turn it widthwise to clean under ladders and awning bars. Attach to your Mary Moppins Fiberglass Extension Handle with ACME threads. Our Lambswool wash pads and mitts come on real leather hide of the sheep giving you years of excellent service. Do not waste your time and money on less expensive pads that are glued to a fabric backing or synthetic pads that can scratch your finish.
