Just a FYI, got a two year old Bosch dishwasher that slowly eroded in performance. Spots that were unheard of started appearing and then plates were not getting clean. $7 on a bottle of Dishwasher Magic cleaned it up like new and it is working perfectly. I can't think of a better purchase in the last year. Something actually worked as advertised!

I think it is worth using this avery 4 months or so. Tang can clean up the deposits really well, but the secret to the dishwasher magic is a wax plug in the bottle that is placed upside down in the washer giving a sort of slow release. I suppose some crafty person could rig up a bottle with wax and Tang to do the same, but life is short!
