If you don't have a mad scientist friend, it might be a good idea to find one.
One of my former college roommates, Scott Tomcyzk, is a scientist working for an industrial chemical lab. The man knows his chemicals: I remember nights when we were roommates when, while talking in his sleep, he'd recite the chemical formulas for various household substances (I kid you not...he did).
So a few years ago, I saw this informercial for this supposedly miraculous stain remover that could remove ANY stain. A bit skeptical, I ordered a tube.
So after I got the stain remover, I tried it on a few old stains that had been impossible to remove. Sure enough, the stuff worked like a charm, taking out every stain I used it against.
I wondered what this stuff was made of, so I took the tube to Scott and he brought it to the lab to test it out. A few days later, he came back with the results. He listed what he determined to be the constituent ingredients, none of which I could identify.
But Scott did tell me to get rid of the stuff as soon as I could because it was highly corrosive.
So I did.
The point of all this, I suppose, is that it's good to have a mad scientist friend.
