salt scratch the surface of a cast iron flat top grill?

You should not use salt to scratch the surface of a cast iron flat top grill. Here's why:

* Salt is abrasive: Salt crystals can scratch the surface of your cast iron, damaging the seasoning and making it more prone to rust.

* Salt doesn't remove stuck-on food: While salt can help absorb moisture and make cleaning easier, it won't effectively remove stubborn food particles.

* Better alternatives exist: There are much safer and more effective ways to clean your cast iron flat top grill, like using a good quality cast iron scraper or a stiff brush.

Here's a safer and more effective approach:

1. Let it cool: Allow your grill to cool down completely after use.

2. Scrape off loose debris: Use a cast iron scraper to remove any large food particles.

3. Clean with a brush: Scrub the grill with a stiff brush, using hot water and a mild soap (like dish soap).

4. Rinse thoroughly: Remove all soap residue with hot water.

5. Dry completely: Dry the grill thoroughly with a clean cloth or paper towel.

6. Re-season: If necessary, re-season your grill with a thin layer of oil.

By following these steps, you can keep your cast iron flat top grill in excellent condition for years to come.
