We use our small George Foreman grill a lot, and have a great tip for easy cleaning. Once we take the food off the grill and unplug it, we take a doubled up paper towel and wet it, wring it out just so there is still wetness to it. While the grill is still warm, lay the wet paper towel on the grill and close the lid. By the time you're done with dinner, clean up will be a snap. This works every time and saves from having to scrub!

How do we clean a George Foreman indoor grill? A sponge came with it, but it does nothing for cleaning up the grill after using. Thanks for any help.

I normally wet an old dish cioth so it's soaking wet, and make sure the grill is either sitting in the sink, or on something that will catch the spillage. Close the lid on it so the wet cloth hits top and bottom. After letting it sit a bit, I'm always able to simply wipe out the residue with little to no effort.

A tip I learned from the lady handing out samples in the grocery store: I line my GF grill, top and bottom, with aluminum foil. Clean up is no longer a problem.
I have a George Foreman grill and someone cooked fish it in. I have tried cleaning it but it still smells like fish. I am not a big fan of fish. Does anyone have any tips for removing the smell? Thanks, Diane
Heat it up to maximum and keep it hot for an hour or so. The fish odor will burn away.

Spray with vinager and then sprinkle with baking soda let sit for a few minutes and rinse.

Wipe it down with lemon or vinager.
