Am I doing most.

This emergency blanket with me for several years in most outdoor activities. I use it mainly as a groundsheet. It is very robust. At home, I wash them often in the shower or with a few drops of soap in the washing machine in the rinse cycle. After years, the aluminum coating has gradually peeled. At the kinks wear some cracks have occurred. The tears I have repaired with small pieces of duct tape and the ceiling is still usable.
