I used to use the traditional green and yellow Scotch-Brite Heavy Duty Scrub Sponge, right up until I was alerted to the fact that it destroys pots and pans.  It's really good at cleaning off hard-to-clean objects, but it's essentially sand paper, so it gradually degrades the surface of whatever object it's cleaning.  That's when I was introduced to the Scotch-Brite Delicate Duty Scrub Sponge.  It has essentially the same cleaning power, but it doesn't cause any permanent damage.  As the resident dishwasher in my house, this sponge is my best friend. #products
