How can we prevent dishwasher detergent residue?
Our dishwasher leaves a residue of detergent on everything we wash, especially glasses and plastic baby bottles. We've tried different detergents (powder and liquid), changed the amount of detergent (more and less), we use Jet-Dry, we've increased our water temperature, but the problem is still occurring. Does any one have any ideas for preventing detergent residue on dishes in the dishwasher? We're also looking for nontoxic detergent options.

Stay Away From Gel Detergents
I know gel detergents are bad for dishwashers, so stay away from those. Have you looked at the sprayer arms? Could they possibly be gunked up? You might try putting some CLR in the bottom and letting it sit all day and then run it thru a cycle. You could have hard water, too, which means you'd have to have a detergent with a higher PH level. That's all I can think of right off.
I think most of the kind of problem you described comes from the water that is used to wash the dishes. I have my own well and have very hard water. I have no problems with spotting or residue left on dishes. I use Electrosol powder or gel. I usually put powder in the first container and gel in the 2nd, but I only fill them half full. I don't use Jet Dry because I don't need it.
My daughter has the same problem you have. She was overloading her dishwasher and using it on a lesser cycle.

I've noticed with our dishwasher that we get a lot of detergent residue when our water softener is out of salt. When the water softener is working properly I don't even need to use Jet-Dry, and when it isn't working the Jet-Dry does nothing.
Sounds like hard water deposits. Try some white vinegar in the rinse, maybe a lot of vinegar.
Mini-Water Softener System
It's probably not the detergent, but hard water stains instead. You can buy a mini-water softener system for about $45 at Walmart that is just for your kitchen sink and dishwasher. Maybe you could try that!
Put in 1/2 to 1 cup of white vinegar at the beginning of the final rinse cycle. Always works for me! (07/21/2006)

Uses Less Detergent
Have you tried using less detergent? I only fill up one of the 4 sections in the detergent cup and it works just fine. I also really like the Cascade Complete detergent. I don't pre-rinse dishes, and there's nothing left on them after using that.
Jet Dry Dishwasher Cleaner
The once a month dishwasher cleaner is available at Wal-Mart and other stores in the dishwasher detergent aisle. It's called "Jet Dry Dishwasher Cleaner" and is quite simple to use. There is another brand, but as it's not available here, you'll have to find out for yourself.
You pull the tab off the bottle (this exposes the wax plug). You place it upside down in the silverware holder in an empty dishwasher and run the dishwasher on the hottest and longest cycle.
This does a nice job of cleaning the interior of the dishwasher and helping the reservoir/grid where the ground up food accumulates to empty itself.
I know that the ground up food is supposed to be flushed away every time you do the dishes, but my dishwasher isn't doing that. I have had the repair guy over twice and tomorrow will be the next time. Maytag isn't living up to its reputation.
Use Lemi-Shine (you can get it at Wal-Mart). I will not run my dishwasher without it! It cleaned out my dishwasher, all of my glasses are shiny (for the first time in years) and it is safe for my septic tank. (10/23/2006)
I have to used Glass Magic (phosphate) in order to get clean dishes. We have very hard water where I live (central California). I'd rather not have soft water because its bad for the watershed. But, so is phosphate. I've decided that since I run my dishwasher twice a week I'm choosing the lesser of two evils. I have a newer version of the same dishwasher at work, and everything comes out looking great, same water source.
I've read that some dishwashers have a built in water softener. This may explain why some people with hard water don't need to add anything, while some do. Still this doesn't solve my problem tonight. I'm out of Glass Magic, all stores in town are out of it, and my dishwasher is full. I have tried vinegar and baking soda, but nothing works. I will look for that small water softener (thanks) just for the dishwasher though I hate to sacrifice all my undersink space.
Clogged Drain Lines
The white residue can be left by a number of conditions. If you have tried all of the possible solutions mentioned, such as changing detergent, using vinegar, etc. and have had no success the problem is probably caused by poor, improper drain lines/pipes or a clogged or slow drain that does not allow for a proper and complete rinse cycle. Drain lines tend to build up dirt and slow or clog in a similar way as human arteries do. Clean them out!
How can we prevent dishwasher detergent residue?
I used an eco-friendly dishwasher detergent made by Palmolive. It has left a hardened white coating on most of my dishes, glasses, and silverware. I have Jet Dry in my machine, but that hasn't helped. Is there any way to remove these unsightly deposits? My dishes never look clean.
Check to make sure your water is hot enough to dissolve and rinse detergent. Run the hot water at the sink before you start the dishwasher to make sure hot water runs into the appliance. Select options (if available) for extra hot rinse or a sanitizing rinse.
Bar Keepers Friend and Glass Magic
One more thing I forgot to mention. If you notice the coating on the inside of your dishwasher, you should clean that with the Barkeeper's Friend also. If you don't, the Glass Magic will get it off over time, but in the meantime, some of the residue that is on the inside surface of the dishwasher will continue to be re-deposited on your dishes. BKF and Glass Magic will work. I promise!
I thought my glassware was etched and ruined too. Nope, just go to WalMart (if you dare) and get a product called Lemi-Shine. Works like a charm.
The troubleshooting section of my new dishwasher's manual says to try using less detergent (up to half as much) and it may stop this problem (while still getting the dishes clean) depending on the hardness of the water.
Cascade! That's the culprit. My husband brought home a new box of Cascade (new packaging) and that's when my dishes went to hell in a hand basket. I also have used the old Cascade for years, and loved it, but this new stuff left my glasses and silverware with a terrible coating of white film that is almost impossible to get off unless I scrub them (after washing in the dishwasher!) with Dish Buds, or some non-scratching metal scrubber. The previous commenter Fanhel was "spot on" when s/he noticed the change in formula. I know phosphate is bad, but Cascade phosphate-free formula just doesn't do the job.
Now that dishwasher detergent makers have taken phosphates out of their detergents, washing dishes in hard water is horrible. I have very hard water and I read numerous forums trying to find a solution. I tried a variety of remedies suggested by this forum and others and here are my results:
Things That Did Not Work by Themselves:
- using hot scrub cycle
- using expensive dishwashing detergent
Things That Did Not Work Well:
- apple cider
- vinegar + hot scrub cycle
- liquid or gel Jet Dry + hot scrub cycle
Things That Worked:
- hot scrub cycle + Glass Magic (phosphates) + Finish Powerball detergent
- hot scrub cycle + Solid Jet Dry that you hang in a basket + Finish Powerball detergent
I ordered the Glass Magic by mail because it's no longer sold in my area (neither is Lemi Shine or any other additive with phosphates). Glass Magic works well, but I am sensitive to putting phosphates in the water system. I learned on the Kitchenaid forum that the solid Jet Dry is more effective than the liquid or gel that goes in the dishwasher dispenser because more of the solid is washed onto the dishes. It really works well and I ordered it by mail because it wasn't sold in any stores around me. On the Kitchenaid forum, I also learned that I must use the hot scrub cycle for hard water and that seems to be true.
If the solid Jet Dry hadn't worked, then I would have installed the Difi, a dishwasher filtration system which goes under the kitchen sink and filters the minerals out of the water before the water goes into the dishwasher. The downside of that system is that the filters must be replaced every month or so and they are expensive at $17.00 each. However, the people who used it said they liked it.
I too was having problems with white residue on especially my plastic items after they came out of the dishwasher. I went to Walmart and looked at various powder dishwashing detergents and all are now phosphate-free which has to be the problem as someone on this blog mentioned earlier. Another blogger mentioned using Lemi-Shine to remove the residue, so I bought it, used it as recommended, and it worked! No more residue. It was so bad that one of my Faberware black spatulas looked gray with residue , but now it's black again. Thanks for the tip. It really really worked!
