Things You'll Need
Burnt-on grease is a common problem when cooking, and your non-stick pans can end up with thick residue that is difficult to remove. While you may be able to scrub certain pans with a scouring pad or similar items, harsh tools can scratch off the finish of the non-stick surface. Instead, use something that removes the burnt-on grease without any scrubbing or harsh tools.
Fill the pan with white vinegar. Make sure the vinegar covers all burnt-on grease residue.
Turn a stove burner on high and bring the vinegar to a boil.
Let the vinegar boil for about five minutes. Notice the burnt residue will cook off the pan.
Turn off the burner, let the pan cool and scrub it with a cleaning rag soaked in warm, soapy water.
Rinse the pan and dry with a clean rag.
