ok, i have read many posts about this here, so when i ran across it for the first time in the store yesterday, i was beside myself. but, then it hit me. i thought i had remembered it being a liquid. the store had 3 different varieties, and all of it is powder. i bought the one that said it was "The Original Lemi-shine" on the package, and hoped for the best. so, did i get the right stuff, and how do i mix it for best results?
