Amanda Blum highlights the importance of winterizing barbeque grills to prevent rusting and extend their lifespan. Rather than merely covering and leaving the grill for the winter season, Blum recommends a series of steps to ensure its performance and longevity. These steps range from examining the grill’s parts and addressing rust to cleaning both its interior and exterior.
  

Key Points: 

1. Regular inspection and replacement of damaged or worn-out parts can prevent moisture exposure that might lead to rusting during winter.
2. Burning off food residue at the highest heat facilitates easier rust identification and removal. Rust can be effectively tackled using tools like a stainless steel scrub attachment and rust removers.
3. Cleaning both the interior and exterior of the grill is crucial. The interior may have carbonized grease that affects food taste, while the exterior needs a specific cleaner for its material.
4. For gas grills, it’s vital to check the burners for proper ignition and alignment, cleaning, and replacing parts as necessary before covering the grill for the season.
