Care and Cleaning
Maintaining the appearance of your Trex Enhance railing is important. The occasional wash is recommended as over time your railing may show signs
of weathering as a result of exposure to the elements. The frequency of cleaning will depend on the environment and exposure to various types of
elements.
» Clean railing using a standard cleaning vinegar or mild soap and water.
» For more detailed cleaning recommendations please refer to the Trex Railing Care and Cleaning guide found on www.trex.com.
