Scrubbies are used for a variety of cleaning chores.
They are great for cleaning non-stick cookware and
glass bakeware, and glass shower doors.  I use them
myself and I would never think of  going back to
something bought in the store.  They are machine
washable, but I learned the hard way to NOT put
them in the dryer.  It is best if you air dry them.
  I have a variety of fun colors to choose from.
 
$1.50 each with no shipping and handling.
