Rubbing with a slightly moistened foam may remove otherwise "uncleanable" external markings from surfaces. For example, melamine foam can remove crayon , marker pen , and grease from painted walls and wood finishings, plastic-adhering paints from treated wooden tables, and adhesive residue and grime from hubcaps .

Urea-formaldehyde insulation releases poisonous formaldehyde gas, causing indoor air quality problems. The chemical bond between the urea and formaldehyde is weak, resulting in degradation of the foam cells and emission of toxic formaldehyde gas into the home over time. Furthermore, some manufacturers used excess formaldehyde to ensure chemical ...
The Carpet America Recovery Effort or CARE is a joint industry-government non-profit organization whose mission is to develop market-based solutions for recovering value from discarded carpet. CARE was established on January 8, 2002 and their initial goals included a 10-year plan to increase the recycling and reuse of post-use carpet materials.
Paraformaldehyde can be depolymerized to formaldehyde gas by dry heating [2] and to formaldehyde solution by water in the presence of a base, an acid or heat. The high purity formaldehyde solutions obtained in this way are used as a fixative for microscopy and histology. The resulting formaldehyde gas from dry heating paraformaldehyde is flammable.
How to Remove Water-Based Paints from Carpet If your carpet has been stained by water-based paint, such as acrylic or latex paint, Osborne recommends beginning with the gentlest method: warm water ...
Formaldehyde (/ f ɔːr ˈ m æ l d ɪ h aɪ d / ⓘ for-MAL-di-hide, US also / f ə r-/ ⓘ fər-) (systematic name methanal) is an organic compound with the chemical formula CH 2 O and structure H−CHO, more precisely H 2 C=O.
During 1999, the United States Environmental Protection Agency (EPA) began an investigation into the class of chemicals used in Scotchgard, after receiving information on the global distribution and toxicity of perfluorooctane sulfonate (PFOS), [7] the "key ingredient" [5] of Scotchgard.
A lower molar ratio of formaldehyde decreases the emission of free formaldehyde from UF products. There is a significant decrease in formaldehyde emissions from UF-based particleboard from F/U molar ratio of 2.0 to 1.0. The German standard for UF resins require the F/U molar ratio to be below 1.2. The U.S. NPA standard is an F/U molar ratio ...
