For the best results, store your gas grill under an awning or other spot where its top is completely covered. Then, use a grill cover to provide additional protection from the elements. Ensure your propane tank (if used) will not come into contact with fire or another heat source. When you uncover your grill for the season or after a long layoff, check for bees carefully. They often enjoy the protection of the cover to get out of the elements.
