Gather the ingredients for making the garbage disposal refreshers. Measure and add the baking soda and salt to a small mixing bowl, and give a stir, ensuring the mixture isn't lumpy.

Now grate the lemon peel into the mixture along with adding the liquid dish soap.

Slice the lemon in half, and squeeze the juice into the mixture. Continue stirring and adding juice until the mixture resembles course sand.

Cover a sheet pan with parchment paper, use a small spoon or scoop to mold the half rounds, and then tap them out onto the pan. A rounded teaspoon measuring spoon works wonderfully. Continue molding the refreshers until the mixture is gone. Allow to dry overnight.
