Cleaning:
Clean spills and messes immediately to reduce possible staining. Some materials can stain the decking if not quickly removed. Ex: ketchup/mustard, fishhooks left to rust, fish blood, bird droppings, etc.
Clean dirt or stains with an all-purpose cleaner with water and a medium-bristle deck brush. Mix the cleaner with warm water in a bucket and dunk the brush in. Work the soapy water into the decking with the brush until the dirt comes up. Rinse with water.
To remove fish blood: Mix 1 cup of bleach with 1 gallon of warm water. Dunk the brush in the bleach water and scrub in a circular motion until the blood is removed. Repeat as needed.
Do not use mineral spirits for cleaning
Upkeep:
Avoid long-term storage of items on the decking such as inflatable pool toys, tools, or water bottles. Keep decking away from reflective surfaces or from under glass. These objects can refract/reflect light, thereby concentrating the beams to a level that can be destructive to the decking.
For longevity after installation, it is recommended that the surfaces be covered or stored out of the sun when not in use.
