Sponge Care Tips from Monticup:

Your sponges will last a long time if you care for them properly.

• TEST YOUR SPONGES FOR COLORFASTNESS BEFORE GETTING THEM WET.
  Dip a small corner of the sponge into cool water. Blot the sponge on a clean white cloth or paper towel. If any color comes off, the sponge is NOT colorfast. Wear rubber gloves while washing a non-colorfast sponge so the color does not get on your hands. Also, do not wash this type of sponge with any other color of sponge.
• How to wash your sponges:
  Sponges may be washed by hand in lukewarm water with a drop or two of liquid soap.
  Don't rub or scrub them hard.
  And do rinse them really, really well.
• How to store your sponges:
  Store your sponges in a container that is big enough not to squash them. Give them room!
  Separate your sponges by color before storing them. Plastic ziplock bags are great for this.
  Do not store sponges of different colors touching each other. The color of one sponge may in time stain the sponge next to it.
  Do not store them in a hot place like the attic, or a damp place. Store them in regular room temperature conditions.
• How to revive your sponges:
  If your sponges get flat from being stored in tight places, or look "bent" from being stored next to another object for too long, you can bring them back to their original shape. Simply wash your hands, and shake the excess water off them. While your hands are still damp, work the dampness into the sponge. You may even lightly mist the sponge and work the drops of water in. The sponge will gradually regain its shape.
• Make your sponges more flexible:
  Some professionals even prefer to work a few drops of water to their sponges right before using them (with clean hands, of course). The sponges will be extra springy from the moisture, and may be easier for you to handle.
