To restore rusted or grimy cast iron grill grates, scrub off old buildup and rust, soak in a 50/50 water and vinegar mix if necessary, and re-season with a high-smoke-point oil (like canola or avocado) over high heat to rebuild a protective non-stick coating.
Reach for the baking soda, even if your cast iron grates don't easily come out of your grill. Make a paste of 1 ½ cups ARM & HAMMER™ Baking Soda, ¼ cup dish soap, and ¼ cup white vinegar in a small bowl. It should be a frothy liquid consistency that sticks to the grill grates.
To make cast iron look new, strip away rusted or flaky layers using a 50/50 vinegar and water soak (for rust) or an Easy-Off oven spray bath (for built-up carbon). Once down to bare metal, scrub clean, dry completely, and apply multiple baked-on layers of oil to restore its non-stick seasoning.

This is totally normal and won't affect your pan's performance. With regular use, the cast iron will darken over time. If your cast iron looks dull, it may be time to saute some veggies to help build up seasoning or reseason the pan in the oven.

5 Cast Iron Cleaning Mistakes Almost Everyone Makes—and How to Fix Them
A cast iron skillet is ruined primarily by rust from soaking or improper drying, warping from extreme thermal shock (like cold water on a hot pan), or cracking if dropped. While most seasoning issues are reversible, letting rust cause deep pitting, or fracturing the iron, destroys the cookware permanently.
Yes, Dawn dish soap is perfectly safe for a well-seasoned cast iron skillet. Modern mild dish soaps are gentle enough to remove food debris and grease without stripping the pan's polymerized non-stick coating (seasoning).
Wear and tear is normal in residential pipe systems. One frequently asked question is “How long do cast iron drain pipes last?” Cast iron waste pipes last anywhere between 50 and 100 years. However, it may be time to replace cast iron pipes long before their lifetime is up.
