Very interesting about the hand sanitizer Chutzie, I will try to remember this.
I save expired credit cards to use as scrapers when filling holes in the walls from nails before painting. They can also be used anytime you need to scrape something off and you don't want to damage the surface.
This one has been around for awhile but I use dryer sheets to put in pans if something is stuck in them and it loosens it up.
To clean the microwave I put a cup of water in it til it comes to a boil and leave it in there to steam off the grime so it can be wiped out.
luv and hugs
