This one is by far our favorite tip. We call it: Mushy Cleaning Gunk. Simply mix a half cup of liquid starch (which is just a water and cornstarch slurry) with 4 ounces of Elmer’s glue and a ¼ cup of water. Mix this all together and you will come out with a slime-like substance. It’s sticky enough to pick up dirt and debris in even the most hard to reach places, but will still hold together and not break apart into pieces.
