To clean a BBQ effectively, follow these key steps:

1. Choose proper cleaning tools, such as a grill brush with scraper, galvanized scourers, microfiber cloths, and a powerful degreaser.
2. Clear off loose debris by scraping out ashes or coal and brushing off loose food particles.
3. Soak the grill grates in warm soapy water or a mixture with white vinegar and baking soda if heavily soiled. This softens stuck-on grease and food.
4. Scrub the grates and inside surfaces with a grill brush or scourer, applying degreaser as needed to break down grime.
5. Rinse thoroughly with warm water or a hose to remove all cleaning residues.
6. Dry the BBQ, then for gas BBQs, fire it up moderately to evaporate remaining moisture and prevent rust.
7. Clean rusty utensils by soaking them in white vinegar overnight and scrubbing off rust with a wire brush.

Additional tips include rubbing the hot grill with half an onion on a fork to remove burnt-on food and wiping handles and exteriors with antibacterial spray or soapy water. Regular cleaning ensures hygiene, prevents rust, enhances flavor, and prolongs the BBQ lifespan.
