These white foam cleaning sponges are a very common tool in the cleaning aisle. If you don't ask questions and just use it as it is intended, it works great to remove scuff marks, stains and things like that. But this magic sponge is made from melamine and formaldehyde. Melamine is a type of abrasive plastic. In Europe it is classified as a "Substance of very high concern".
The International Agency for Research on Cancer classifies melamine as possibly carcinogenic to humans. When melamine is used with warmth, in addition to anything acidic, it leeches more of the product out into the environment(or your hands!). I have found other less toxic substances that get the job done just as well as melamine. Citric acid and hydrogen peroxide are two substances (not mixed together) that have a whitening effect when used, and are not harmful to the environment or to you when used responsibly to clean appropriate surfaces. Other things, like lightly buffing a surface, or even using oil, or alcohol can accomplish the same thing as melamine foam.
