Our covers are made from a high-density polyethylene fabric that is naturally resistant to dirt and mildew. However, we suggest cleaning any soot or grit from the cover at least once a year to help maintain its vibrant color.
Cleaning may be done with a mild liquid dish washing type detergent and a broom (if the cover is already removed from the unit); or a hose system used for washing external windows.
We suggest cleaning the steel of your unit at least once a year, ideally during cover removal or reinstallation. Cleaning may be done with a mild dish liquid and a sponge.
