What causes grill grates to rust?
The primary cause of rust on grill grates is exposure to moisture and air. Most grill grates are made from materials like iron or steel, which are prone to oxidation when they come into contact with water. This can happen due to rain, spills, or even condensation, especially if the grill is not covered when not in use. Over time, this oxidation process leads to the formation of rust, which can compromise the integrity of the grates.
Another contributing factor is neglecting maintenance. If grates are not routinely cleaned and seasoned with oil, the protective layer that prevents rust can wear away. Food residues can trap moisture against the surface of the grates, accelerating the rusting process. Proper care, including regular cleaning and drying after use, can significantly reduce the likelihood of rust developing on your grill grates.
Is it safe to grill on rusty grates?
Grilling on rusty grates is generally not recommended.
