Just a heads up: on the Magic Eraser.
Read the contents: when they first came out they contained formaldehyde!
Not something you want to use without rubber gloves!!

Magic Eraser is actually something called Basotect that is manufactured by BASF. It's been around for decades and is used in a wide range of applications, including thermal and sound insulation. It's safe, stable and there are no known hazards associated with it's use. Repeat: after decades of use in a variety of conditions, there are no known hazards. You can read the Material Safety Data Sheet for yourself.
Basotect is a condensate formed formaldehyde melamine co-polymer, so it always has been and still is made with formaldehyde. Formaldehyde is H2CO (hydrogen, carbon and oxygen, for those without high-school chemistry) so you know it must be scary stuff! It's important to understand that Basotect contains no unreacted formaldehyde - that is to say that there is no formaldehyde in Basotect, it has all been consumed during the manufacturing process. You're in more danger from aluminum foil than you are Magic Erasers.
I'd tell you to put a Magic Eraser in your pipe and smoke it, except that the stuff is highly flame resistant.
