Need to close the rinse aid cup.
The Slushy Magic cup, lid, and spoon straw are dishwasher safe. The magic freezer cubes just need to be rinsed by hand. Hope this helps.
Ceramic cups can be placed in the oven, but make sure the cups are heat treated and dishwasher safe, do not use plastic. Use paper cup liners so you wont have a hard time releasing the cup cake.

My brother in law works for a commerical dishwasher repair service. My dishes were looking terrible. He suggested lime away. they look great. I ran them in the lime away and then added an extra rinse. I used about a cup in the dishwasher.
1. The dishwasher sucks, AND/OR 2. The coffee/drink which was in the coffee cup was too much for the coffee cup, or a chemical present in the drink stains the cup permanently.
Its not very likely.
Pour a cup of bleach in bottom and run it empty.
Get a cup and a bucket and start bailing. Three stooges style!
I would suggest a tumbler or travel mug, they sell for pretty cheap and most can be handwashed and are dishwasher safe!
Make sure the dishwasher door is securely closed. Select the desired wash cycle and any additional options. Add dishwasher detergent to the dispenser. Press the start button to begin the cycle.
