Melamine Foam Bulk Magic Eraser Sponge

Magic sponge erasers are made from melamine, an organic compound with a wide variety of uses; in fact, you’ll find melamine used in everything from sound-dampening materials to dinnerware sets. 

Magic Eraser Sponge is formed differently from other cleaning products and only needs water to effectively remove most stains -- no detergent or soaps are required. The only fault is that melamine foam erasers wear out quickly -- just like pencil erasers do. To all outward appearances, however, melamine foam erasers look and feel just like an ordinary sponge. To view the crucial properties of melamine foam, you need to go down to the microscopic level. This is because when melamine resin cures into foam, its microstructure becomes very hard -- almost as hard as glass -- causing it to perform on stains a lot like super-fine sandpaper. How can this foam be like a sponge if it is almost as hard as glass? Because it's a special type of open-pore foam.

Closed-cell foam is easier to visualize, so let's start there. Types of closed-cell foam are usually more rigid because they retain most of their air pockets intact, like a bunch of balls all crammed together. For open-cell foam (typically the more flexible), imagine that those balls have burst, but some parts of their casings remain. You can picture a squishy sea sponge as an example. In airy melamine foam, only a very limited amount of casing stays in place, and the strands that do are located where the edges of several air pockets overlapped. The foam is flexible because each tiny strand is so slender and small that bending the entire eraser is easy.

When the rigid crystal structure of melamine is processed, it turns into melamine foam, which is the generic name for magic foam sponge. The melamine foam has a superfine, high-strength structure that behaves a lot like sandpaper with a nearly microscopic level of grit.

The cavity-ridden open microstructure of melamine foam is where the second major boost to its stain-removing capabilities comes in. Except for being able to scrape at stains with extremely hard microscopic filaments, with a few quick runs of the eraser, the stain has already started to split. That's aided by the fact that the dirt is pulled into the open spaces between the spindly skeletal strands and bound there. These two factors combined make this next-generation eraser seem almost magical.

Compared to conventional sponges, Topeco Clean magic sponges have some advantages. These sponges only require water to eliminate messes — meaning you won’t need to burn through chemical cleaning products (and plastic packaging). 

Magic Sponges Erasers can also typically be used more times, making them preferable to paper towels and other single-use products. In the end, Melamine Sponges are also safe, and worth using.
