The WipeOut Eraser is a chemical free cleaning pad that is such a different approach to cleaning, it is often difficult to understand how and how well it works!
The product is actually Melamine Foam; and frankly, wikipedia explains it quite well:
In the early 21st century it was discovered that melamine foam was an effective abrasive cleaner. The open cell foam is microporous and its polymeric substance is very hard, so that when used for cleaning it works like extremely fine sandpaper, getting into tiny grooves and pits in the object being cleaned. On a larger scale the material feels soft. Because the bubbles interconnect, its structure is more like a maze of fibreglass strands, when compared to the array of separate bubbles in a material such as styrofoam, for example.
Rubbing with a slightly moistened foam may remove otherwise "uncleanable" external markings from surfaces. For example, it can remove crayon, magic marker, and grease from painted walls, wood finishings, plastic-adhering paints from treated wooden tables, adhesive residue, and grime from hub caps. If the surface being cleaned is not sufficiently hard, it may be finely scratched by the melamine material. The foam wears away, rather like a pencil eraser, leaving behind a slight residue which can be rinsed off.
In the boating world, it is commonly used on dinghy pontoons, fenders, and power cords, as it is a great way to clean those rubbers without solvents, which can do longterm damage (acetone blisters and dries cords). Ralph Perez, the inventor, touts the product for other harder surfaces, such as nonskid and scum lines, which it works well on, but we tend to use more traditional chemicals just because of the large volume of these areas we do. For the owner though, it would be great for getting stubborn spots from these areas.
WipeOut is considerably larger (40%), and I believe it be structurally different from his mainstream competitors. The size difference leads to exponentially more longevity because once you wear the pads down to less than a quarter of an inch thick, they become difficult to use. Also, the WipeOut version has a backing pad, allowing a little more stiffness while scrubbing, a scratch free surface you can use to loosen up dirt, as well as a plastic handle designed for larger jobs such as decks or hulls.
