Polycarbonate conservatory roof sheets should be cleaned periodically to ensure that the sheets continue to perform at their best. The following is a good process to start with:

  • Rinse sheets with lukewarm water to prepare and soften dirt
  • Mix household cleaner, or mild soap, to clean lukewarm water
  • Gently remove dirt and grime with a sponge or soft cloth. Use the soapy water mix
  • Repeat the process
  • Rince the sheet and dry with a soft cloth.

REMEMBER: Don’t scrub with brushes or sharp instruments. Do not use solvent, abrasives or high alkaline cleaners. Always test cleaners on a sample sheet – even if it claims to be safe for polycarbonate.
