THIS REALLY DOES WORK!!! (great to remember for move-out or in) Place a dishwasher-safe cup filled with plain white vinegar on the top rack of the dishwasher. Using the hottest water available, run the dishwasher through a cycle. The vinegar will help to wash away the loose, greasy grime, sanitizes, and helps remove the musty odor. Next, sprinkle a cupful of baking soda around the bottom of the tub and run it through a short cycle. The baking soda will help freshen and removing stains.
review from amazon ROG 3 Tub and Tile Bathtub Cleaner K-1 Kit I have a kohler tub for about a year now, when the slip guards started to look dirty I was on a mission to get them cleaned. I tried most everything recommended nothing worked until I got R.O.G. It took two applications to get them cleaned so I suspect if your tub is very stained it will take work for you to get them clean. I maintain the tub now with this product. I would buy it again.

Clean lime deposits and iron stains inside the dishwasher by pouring a packet of lemonade Kool-Aid (the only flavor that works) into the detergent cup and running the (empty) dishwasher. The citric acid in the mix wipes out stains; you don't have to.
