Will the Professional Grade Vinyl Renu™ Cleaner or Shutter Renu™ damage my siding, stucco, cement board, windows, etc?
No. Professional Grade Vinyl Renu™ Cleaner should be thoroughly rinsed after cleaning. Any Shutter ReNu that gets on windows should be cleaned quickly. Any Shutter Renu™ that gets on other surfaces can be allowed to dry clear or rinsed with water quickly after accidental application. If you siding is faded Shutter ReNu will restore any area that it touches. You can purchase Vinyl Renu™ for your faded siding to bring back the beautiful color of your siding.
