Melamin Sponge

Melamine sponge, also known as "magic sponge" or "melamine cleaning sponge," is a cleaning tool made of melamine, a type of plastic material. It is used to remove stains and dirt from a variety of surfaces. The melamine sponge lets its microscopic structure remove dirt and stains by scraping the surface, making it effective for cleaning, but at the same time it can also leave small scratches on soft or delicate materials such as paint, plastic or polished wooden surfaces.
To avoid damage or scratches, you should be careful about which surfaces you use the melamine sponge on, and it is recommended to test it on a small, invisible area before using it on larger surfaces.
