I have used Scotch Brite Heavy Duty sponges to clean the water stained areas around window seals. It removes the build up and black stains that sometimes occur due to moisture from the glass windows. Using a little liquid soap and this powerful sponge usually returns the window seals to their original condition.
My cookware is very old and aluminum. It was very high quality in its time. It had become very stained and discolored. Using the heavy duty scrub sponge with a little old fashioned cleanser and elbow grease I was able to restore it to almost its original splender. Enough so that I no longer want to replace it.
i love the heavy duty sponges, i can scrub my tough cooked on pots and pans and with little effort they come clean.. they also last awhile.. alot longer than those cheap ones..
This sponge works very well in cleaning all surfaces as well as dishes without leaving a "green residue" like other brand sponges out there. They are durable and efficient... the only downfall to them is that they tend to smell foul easily... wish there was a way to keep the smell away.
