Berkley Jensen Heavy Duty Cellulose Scrub Sponges, 27 ct.

I used one to scrub my tennis shoes and they came out looking brand new.

They hold their shape well and don't get all misshapen after a couple uses.

Great for getting into the grooves of a cast iron skillet to clean it properly.

The pack is so large I was able to give a few to my neighbor to try. Now she's hooked too.

I use them to apply wax to my car before buffing. The texture holds the product perfectly.
