What is the recommended cleaner for our 9 month old Azek deck? Slate Grey and only slightly soiled from winter conditions in central PA .

To clean AZEK Deck/Porch, use all-purpose cleaner and dilute all cleaners by 50% (Do not use full strength) , such as Chomp Gutter cleaner, Zep 505, Simple Green or Krud Kutter Cleaner/Degreaser with a stiff natural fiber brush. 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. Always clean smaller, manageable areas and rinse often, do not allow cleaner or soap residue to dry back to surface prior to thoroughly rinsing.
