You are doing everything wrong. Here’s the best way to clean grease from a griddle

Choose a cleaning solution that is safe for your iron’s material. Spray or pour it directly onto the greasy surface.
4. Let the cleaning product sit.
Let the solution soak into the grease for 5 to 10 minutes so it can effectively remove the buildup.
5. Rub with a non-abrasive pad
Use a nonabrasive scouring pad to apply the cleaning solution to the grease, scrubbing until most of the grease is dissolved.
6. Rinse and dry
Use a damp cloth to wipe away dissolved grease and residue. Follow up with a dry cloth to ensure the surface is completely clean and dry.
7. Inspect and repeat if necessary.
Check the surface for traces of grease. If necessary, repeat the steps above for a deeper clean.
Properly cleaning your iron doesn’t have to be a daunting task. With these steps, you can ensure it stays in tip-top condition, ready for your next culinary adventure.
