How to Get Hard Water Spots From Your Dishwasher Off

Take additional measures to keep your dishes spot-free.

If you have hard water -- water with high concentrations of minerals such as calcium and magnesium -- you've got a hurdle blocking you from getting clean dishes, cups and other kitchen items. Even with a dishwasher and a suitable detergent, hard water can prevent them from getting thoroughly cleaned. If you notice that your kitchen items have hard water spots on them after cleaning, take measures to remove the stains so you can restore their natural appearance.

Things You'll Need

• White vinegar
• Dish towel
• Baking soda (optional)

Instructions

1. Fill the sink up about halfway with plain white vinegar.

2. Place your cups, silverware, plates and bowls in the vinegar. Allow them to soak for at least one minute.

3. Remove each item from the vinegar, rinse with warm water, and then dry them with a dish towel.

Tips & Warnings

• Run a cycle with vinegar in the rinse-aid dispenser and baking soda in the detergent dispenser if you're limited on time.

• Run an empty cycle once a week with a bowl of vinegar in the bottom rack. It helps prevent hard water buildup from forming inside the appliance.

• Use a rinse aid with each load of dishes you wash in the dishwasher to prevent hard water buildup.
