Tips

  • Avoid using water or soapy water to clean the grill's interior, as this will introduce moisture.
  • If you do use water, ensure the grill is thoroughly dried and fired up afterward to remove all moisture.
  • Clean the lower area of your grill every 3 to 6 months to prevent rust.
  • The goal isn't to achieve a spotless clean, but rather to remove the majority of the grease, ash, and debris that attract moisture and lead to rust.

Common Mistakes to Avoid

1. Neglecting to completely dry the undercarriage

Reason: Moisture trapped under the grill provides the perfect environment for rust to form, even after cleaning.
Solution: Thoroughly dry the undercarriage with a clean cloth or paper towels, paying close attention to crevices and hard-to-reach areas.

2. Using abrasive cleaners or scouring pads on delicate surfaces

Reason: Harsh cleaning agents can damage the grill's finish, leading to premature rusting and deterioration.
Solution: Opt for mild soap and water, a soft bristle brush, or a non-abrasive grill cleaner.
