Does your dishwasher
 

remove coffee and tea stains from cups and mugs? If so what kind is it?

those types of stains may require something done by hand. Baking soda is a great way to clean these. I've also used Soft Scrub BUT you have to rinse VERY/VERY/VERY well.

These are not set in stains. I have to pre-scour my mugs every time before I put them in my dishwasher or they so not come out clean.

I remove coffee stains from my mug by spraying Tilex that contains bleach in the mug and let it sit for awhile. All stains are removed.

I prefer X14. It not only takes out the stains, but continues through the mug, the saucer, the countertop, the cabinet floor, the floor, and the slab. B4 you know it there is some small guy yelling at you in Chinese!

Fill the mug with warm water then drop a Polident Denture tablet in the mug. Works wonders for stains.

Try Cascade Platinum pods. If that does not work, as Not Golfer suggested, baking soda works great.

I wouldn't use anything with an abrasive, like soft scrub or scouring powder. It will damage the surface and cause it to stain even worse. I think that anything with bleach will remove the stains, but you need to make sure you rinse very well.

Bosch dw gets almost everything but if you have a stained cup and continue reusing it, I would leave bit of vinegar and water in it for a short time, the entire put in DW. I run my Bosch on quick wash all the time and unless it is baked on egg, expect it to be clean.

Also, I was told new detergents are less adequate than they us to be. I use Walmart brand cubes...no problem....and they are inexpensive.

Thanks, Bosch was one I was considering. I am also on the fence about the Frigidaire Gallery since that is the one that would match my other appliances but cleaning ability is my first consideration.

We have the GE Profile and I always use temp boost and pot/pans cycle with Cascade Platinum pods. Also run water at sink til runs hot before pressing diswasher start. Never a problem with the heaviest messes or stains.

Good to know

No problem with coffee or tea stains, we just rinse cups out after use, or let water stand in them over night, and throw into the dishwasher (original Whirlpool that came with the house). NOTE we do have a water softener and whole house filter, and use Cascade liquid detergent, as for settings we use 'sensor', ECO dry. The only things that do not always get clean are knives with peanut butter or similar on them.

Original Whirlpool is what we are replacing. I did suspect that water may be the problem. We come from the granite state where there are not so many minerals in the water. We don't like water softener though as doctor once told us that they are not good for people with HBP because of the salt.

try powder cream of tartar , its a spice

I have found that Mr Clean eraser does get the stain out but just thought that there should be a dishwasher that could handle this without pre-scrubbing

The amount of sodium (not salt as the chloride is stripped off) that is added is very minimal - much less than other sources in a typical diet. The rule of thumb is about the amount you find in a piece of bread. If even that amount is too much, use potassium chloride instead of sodium chloride as a regenerate.
