The only question is, "How do I clean my composite decking and railing?"

DecksDirect Pro Tip:

To clean tough blemishes like tree sap, honey or dried foods from your Trex composite products act fast and try these three manufacturer-recommended methods.

1) Trex recommends using warm, soapy water to start. Use a mild, liquid dish soap such as "Joy®" or "Dawn®" and add roughly 1/4 cup of soap to 1 gallon of warm, clean water. With a soft new sponge, lightly working out and loosening the stained spot. When clear, rinse off the former blemish, and towel or air-dry the composite material.

2) In an inconspicuous area, test a cleaner such as "Goo Gone®" or mineral spirits and very lightly scrub the area, checking often for discoloration. If no discoloration occurs, continue applying the cleaner directly to the sap or stain maintaining a light, scrubbing motion. Warning -- heavy scrubbing motions will cause discoloration of composite boards and railings.

3) Have large drops of tree sap, honey etc? Place ice in a sealed bag and set the bag over the sap area. Leave on for 20 to 30 minutes, letting the stain to dry and harden. Once ready, use a putty knife or razor to gently chip off as must of the area as possible. Be very careful not to cut or trim the composite decking or railing.
