Water stains on some glasses

your alkalinity is way too high. It shouldn't be above 7.8... 7.4 - 7.6 is ideal. I use muriatic acid to lower my ph. Also, your alkalinity is too high. should be between 80 and 120.
There is a sequestering agent you can use to try and drop the metals out of the water, if any are present. You stated you had high iron.
However, before tackling the iron, you need to get your ph under control. Chances are if you get your ph and alkalinity in line, your water will look a whole lot better.
If it is still cloudy, I would use a floc product.

Hello -

The cause of the stains on the interior of your dishwasher may be the water. Do you know if you have hard water, water with a high mineral content? If so, do you know if the water has a high iron or maganese content?

If you have hard water in your home water supply and do not have a water softener, check the owner's manual for your dishwasher - the Troubleshooting section - to see if there is mention of stains on the interior of the dishwasher.

Yellow / Brown Stains

Causes:
Iron or manganese content in water supply.

Solutions:
After food soil is removed, wash dishes with citric acid crystals. Check dishwasher manufacturer's instructions for amount to use and method. Do not add detergent.

A liquid product is available to remove iron deposits from the dishwasher interior; follow the package instructions.

To retard staining, use maximum amount of dishwasher detergent to keep iron or manganese in suspension during the wash. Use a rinse additive during the rinse.

Preventative Measures:
If staining cannot be controlled, the only solution is in the installation of iron removal equipment in the home water supply.

Some solutions to the interior staining problem recommend the addition of citric acid crytals to the covered section of the dishwasher detergent dispenser. If you do that, be sure you do not have any sterling silver or silver plate tableware in the dishwasher. (Those items are best washed by hand, anyway.) Citric acid will cause pits on sterling silver and silver plate. Note: Some dishwasher detergents and dish liquids have citric acid in their formulations - check the ingredients.

Best wishes.

Its a real pain, but use only distilled water.

Fill your iron with white vinegar and let it steam until empty.. face down on a towel on lowest steam setting.

I have had customers that have complained of this. I my area it is usually related to hard water a iron in the water rather than being the fault of the washer. The washer and the clothing is just the place that it is most noticable. For these customers a water softener has solved the problem. You should get your water checked for hardness and iron it may be the problem. Another thing that it could be, is if you have iron piping in your house. Rust from inside the iron piping can flake off and stain your clothing. Just a few things that you can check out....

The first place that I'd check would be the small metal screens inside the openings on the water inlet valve. They can get really rusted, epecially in areas with hard water, so I would recommend removing the water supply hoses and take a gander at the screens. They can sometimes release the iron oxide into the wash water and cause brown stains or blotches on clothing. Hope this helped and best wishes.

Windex and newspaper should do. You sure they are water spots and not the glass? When they set out the plastic impregnated in the glass (safety glass), seperates slightly and looks like a water spot or even a bubble. It is a combination of heat & sun rays. May have to live with it or replace the glass.

Check for iron content of the water in your area. Excessive iron will clog the zeolite beads in your softener and reduce its life. You can try increasing the backwash and rinse cycles to see if it helps. You can also get an iron pre-filter for a softener. I am assuming you have either a private well or a municipal well.

Norwex Descaler is the absolute best thing I've found for hard water build up on any surface, including glass shower doors and shower/sink fixtures. When I moved into my current house last year, the bathtub and shower head were disgusting! They were white with years of built-up hard water residue. Repeated application of CLR and a ton of elbow grease just couldn't get it off. When I tried Norwex DeScaler for the first time, it removed ALL of the soap scum and lime in the FIRST application.

This stuff is enzyme based - free of hazardous chemicals and enviro friendly. The enzymes in the DeScaler actually eat the soap scum! I just spray it on, wait 5 -10 minutes, and wipe off with my wet microfiber cloth (also from Norwex). It's incredible. It works better and faster than CLR, or any other chemical alternative I've tried. It's fume-free and can be used by people with chemical and environmental allergies.

You can buy it from a Norwex Rep, or order it online - a good site is www.Norwex-Healthy-Cleaning.com. Hope this helps.
