[quote=shequilts]OK, now you'll all know how really old I am: My mom and grandmother used these inserted into a brown glass Clorox bottle. It was a little smaller in diameter than a 2 liter bottle. I can't imagine how many years since they put chloring bleach in glass bottles.
I remember my Mom calling Clorox "One-o-One." I am 66 today and that was a long time ago. My Mom is 93 and still calls it "One-o-One."
