Two days ago, I was at a mall with my ex and at a shop somewhat like Dollar Tree, we saw a very unusual sponge. It is white, 11 inches long, 3 inches wide and two inches deep. What makes it so unusual is that it can be used to clean most things without any soap, detergents, etc. You just get it wet and then wipe off whatever you are cleaning. I was doubtful but decided to buy it, figuring that if it did not work I could use it as a regular sponge. I then tried it on my bathroom sink which was, to say the least, rather dirty and with no effort on my part at all a single swipe had the sink shining. I can't tell you the exact name of it as it is written in Hebrew and Hebrew has no written vowels. The closest I can come is either "Nofer" or "Nufer". It does not say what it is made out of (it does say it is kosher but I can't imagine what would make a sponge unkosher). It says on the package that it cleans plastic, marble, ceramics, brass, steel, bathtubs, pipes, ovens, microwaves, cars (but not with metallic colors) "and other things", I have never seen this kind of sponge before and neither has my ex. I also have no idea of how it works. Does something like this exist in the States?
