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.
Please do not try milk or toothpaste these are silly ideas that will leave sticky residues on the surface which will help to break down the finish on your leather. Magic erasers usually remove finish and pigment along with the ink. We have just tested these and they really do a lot of damage on leather.f the ink is on a pigmented leather then the first thing you should try is an ink stick (find one that is a professional product used in the industry-LTT do one). The fresher the ink the more chance you have of removing it.
