How to Remove Black Streaks From a Camper


Campers make vacationing comfortable, flexible and affordable. Keeping camper exteriors well maintained is significant to their appearance. A mixture of oxidation, soil, bird droppings and insoluble oils from rubber, fiberglass and thermoplastic polyolefin roofs runs down camper exterior walls during rainfalls and heavy dew, creating black streaks. These black streaks become harder to wash off a camper the longer they go unaddressed. Promptly remove black streaks before they become irreversible eyesores on a camper.

  • Water-displacing lubricant
  • 2 rags
  • Commercial wax-free RV exterior cleaner
  • 2 pails
  • Stirrer
  • Soft brush

  • Spray the black streaks with water-displacing lubricant, applying it liberally. Leave the lubricant to permeate the black streaks for five minutes.
