A magic tablet transforms the gas grill into a jewel:

Procedure

1. Remove the rack and place it in a large container or baking dish.

2. Make a paste with baking soda and a little water (or vinegar).

3. Spread the paste on the grill and let it sit for at least 1–2 hours.
   For stubborn stains, you can wrap the grill in a large bag with a small cup of ammonia and leave it closed overnight (be careful: do this in a well-ventilated area!).

4. Scrub well with a sponge or scouring pad.

5. Rinse and dry: your grill will be clean and shiny again.
