You are doing it all wrong. Here’s the best way to clean the grease off a hot plate

2. Scrape off loose grease and food particles
Use a scraper specifically designed for hot plates, or a spatula, to gently remove large chunks of food and grease.
3. Apply a suitable cleaning agent
Choose a cleaning solution that is safe for your hot plate’s material. Spray or pour it directly onto the greasy surface.
4. Let the cleaning agent sit
Allow the solution to penetrate the grease for 5-10 minutes so it can break down the buildup effectively.
5. Scrub with a non-abrasive pad
Use a non-abrasive scrubbing pad to work the cleaning solution into the grease, scrubbing until most of the grease is dissolved.
6. Rinse and wipe down
Use a damp cloth to wipe away the dissolved grease and residue. Follow up with a dry cloth to ensure the surface is completely clean and dry.
