In passive solar building design, windows, walls, and floors are made to collect, store, and distribute solar energy in the form of heat in the winter and reject solar heat in the summer. This is called passive solar design because, unlike active solar heating systems, it does not involve the use of mechanical and electrical devices.[1]
[pinit] I looked on the back of a Magic Eraser package the other day and noticed there werenât any ingredients listed. That seemed very odd to me since just about every cleaning product out there has some kind of ingredient. I did a quick search and found out Magic Erasers are made of a product called melamine foam.
You'll probably benefit from keeping melamine foam erasers on hand. Now on the market for a couple of years, eraserlike products that get rid of stains you thought you were stuck with for good have become a common household item. For example, Mr. Clean sells a line called Magic Erasers and Scotch-Brite offers a product called the Easy Erasing Pad. The secret behind these types of erasers is a material commonly called melamine foam. With just a little water, melamine foam can dig in and destroy stains that other products can't touch.
