AZEK Deck Frequently Asked Questions (FAQs)

What is the best way to clean AZEK Deck?

  • To clean AZEK Deck, use an all-surface deck cleaner or another all-purpose cleaner such as Simple Green or Krud Kutter Cleaner/Degreaser. Do not use abrasive cleaners which can dull the surface of new deck boards. Always read the cleaning product manufacturers specific information before using any product on your AZEK Deck and follow their instructions.  It is also a good idea to test the cleaner on a scrap piece or inconspicuous area of the deck to make sure it does not harm the surface.
  • For stubborn stains/scuff marks on a weathered AZEK Deck, you may remove or greatly reduce stains/marks with an application of Red Max Pro Degreaser or Krud Kutter Cleaner/Degreaser. The degreasers should be applied to the area and allowed to soak for several minutes. Depending on the stain or mark, some moderate scrubbing may be required using a pot scrubber (such as a Scotch Brite type pad). Depending on the stain or mark, several applications may be required. Deck should be rinsed thoroughly upon completion. Always read the cleaning product manufacturer’s specific information before using any product on your AZEK Deck and follow their instructions.
