Have used it since the seventies, my Grandma before that..since it was new. The best there was! Read on the internet machine that folks were using it for meth????or some sort if drug stuff. Anyway, if they remove the chemical that is used for that, it won't be any good anymore. You ought to be able to use your drivers license to purchase, like decongestant sinus meds. Guess I am getting old. This and Twinkle for your metals kept the house clean and happy.
