Whether you’re packing up your barbecue grill for the season or just want to clean it up for the next round of burgers, here’s an easy way to rid the grime: sprinkle the juicy side of a lemon half with salt. Heat the grill, now spear a long fork into the backside of the lemon and wipe the grill back and forth getting each grate. The acid in the lemon removes the grease while the salt brushes away any gunk and grime.
