MAINTENANCE
Care and Cleaning
NOTICE
Polycarbonate windshields/wind deflectors require proper attention and care to maintain. Failure to maintain polycarbonate properly can result in damage to the windshield/wind deflector. (00483e)
  • Do not use benzene, paint thinner, gasoline or any other type of harsh cleaner on the windshield. Doing so damages the surface.
  • Do not clean in hot sun or high temperature.
  • Powdered, abrasive or alkaline cleanser damages the windshield.
  • Sunlight reflections off the inside curvature of a windshield can, at certain times of the day, cause extreme heat build-up on motorcycle instruments. Exercise care in parking. Park facing the sun, place an opaque object over the instruments, or adjust the windshield to avoid reflections.
  • After washing and drying windshield, make sure that windshield is properly seated in grommets prior to operating vehicle.
NOTICE
Use only Harley-Davidson recommended products on Harley-Davidson windshields. Do not use harsh chemicals or rain sheeting products, which can cause windshield surface damage, such as dulling or hazing. (00231c)
  • Never scrape windshield with a razor or other sharp instruments because permanent damage will result.
  • Covering windshield with a clean, wet cloth for about 15 minutes before washing will make dried bug removal easier.
