Alternative: Oven Cleaner Spray
If you prefer not to use ammonia, heavy-duty oven cleaner can also be used in a sealed bag.
| Step | Action |
|---|---|
| 1 | Place grates in a garbage bag |
| 2 | Spray generously with oven cleaner |
| 3 | Seal the bag and let sit for 8–12 hours |
| 4 | Rinse thoroughly |
Note: Oven cleaner is highly caustic. Always wear gloves and wash the grates thoroughly before cooking.
When to Replace Instead of Clean
While this method restores even heavily caked grates, there comes a time when replacement is the better option.
| Sign | Action |
|---|---|
| Grates are rusting through | Replace for safety |
| Heavy pitting or flaking metal | Replace (food can stick to damaged surfaces) |
| Grates are bent or warped | Replace (unstable cooking surface) |
