What is the best kind of cleaning agent to use for cleaning burned on grease?

The best cleaning agent for burned-on grease is a mixture of baking soda and water, which creates a gentle abrasive paste that effectively lifts stubborn residues. Alternatively, commercial degreasers or enzymatic cleaners specifically designed for tough grease can work well. For tough spots, a vinegar and baking soda combination can also help break down the grease. Always ensure proper ventilation and follow safety instructions when using chemical cleaners.
