grills.jpgA Weber grill is made of solid first-class materials, so you can safely leave your grill on the patio all year round, as it is built to withstand any weather conditions. This is why Weber Grills is willing to offer both a rust and enamel warranty on its grills. If you place a cover over the grill, it is also protected from dirt and moisture, etc. However, it is a good idea to clean your grill regularly, as food residue and dirt can easily adhere and cause undesirable surface rust.
