Use Rinse Aid

Make sure your dishwasher is equipped with a rinse aid dispenser, and use a rinse aid specifically designed for dishwashers. Rinse aid helps prevent mineral buildup and ensures water sheeting action, which leads to cleaner, spot-free dishes.

Choose a Quality Dishwasher Detergent

Use a high-quality dishwasher detergent that is designed to work well in hard water conditions. Look for detergents that contain a water-softening agent.

Regularly Clean the Dishwasher

Clean the dishwasher’s interior, including the spray arms, filter (if applicable), and the interior walls, to remove any buildup of mineral deposits and detergent residue. Follow the manufacturer’s recommendations for cleaning.

Ensure that the hot water supply to your dishwasher is at the recommended temperature (usually around 120°F or 49°C) to help the detergent work effectively.

Load the Dishwasher Properly

Avoid overcrowding the dishwasher, as this can prevent proper water circulation. Make sure that glassware is spaced apart to allow water to reach all surfaces.

Pre-rinse Dishes

While it’s not always necessary, rinsing dishes before placing them in the dishwasher can help reduce the amount of food particles and minerals that contribute to cloudiness.

Use Vinegar

If your glasses are already cloudy due to mineral deposits, you can soak them in a mixture of white vinegar and water. Place the glasses in the mixture and let them soak for a while, then rinse and wash them again in the dishwasher.

Remember that some glassware may have etching (tiny, permanent scratches) due to high mineral content in hard water, and this cannot be reversed. However, by following these steps, you can help prevent and reduce cloudiness on your glassware and keep them looking clear and sparkling.
