Then, I began adding only a teaspoon to the closed cup along with detergent I already had in a stockpile. My dishes just kept getting cleaner and cleaner until one day I said to my husband, "If the dishes get any cleaner, I'm going to have to return them to the store!"  I was showing the sparkling glasses to my son and his wife one day, and I came across one glass that was streaked. I was so disappointed until I realized that was one of the glasses I'd washed by hand! I have some collectible Fire King peach luster casserole dishes and mugs. I thought they were dull from age and scratching. After using Lemi Shine for a few months, they look brand-new! I try to keep a spare container handy in case I want to share some with friends or family. I give them my open container, and I know by the time they finish it they will be buying their own. My sister has an expensive water treatment system in her house, and my glasses look better than hers! I have no water softener or any other kind of treatment system. I have heard there is a new product that I can use in my front loader washer to get it cleaned out, and I am hoping I can find this on store shelves soon. In the meantime, I might just try using some Lemi Shine from the kitchen. I LOVE Lemi Shine! Thank you for making it!
