Query: Don't buy this Cascade--ever!

I've used Cascade for years, but this new one--Cascade powder with Dawn--is awful. White residue on everything and, yes, I've cleaned my dishwasher with CLR, prewashed dishes, adjusted whatever I could and the results are the same. The Cascade website admits to--literally--a 1% satisfaction rate. Beware!
