Tips for Using the Dishwasher

With today’s fast-paced lifestyles, especially in homes where both adults work either outside the home or remotely, automatic dishwashers have become a kitchen essential. Unfortunately, they haven’t yet figured out how to load and unload themselves. (Now that would be a feature worth waiting for!) If your dishwasher isn’t cleaning like it used to, or your dishes come out spotted or dirty, you’re not alone. Below, we break down how dishwashers work, common cleaning issues, and practical solutions to get your dishes sparkling clean again.

How Dishwashers Clean Dishes

Contrary to popular belief, dishwashers don’t fill to the brim with water. Instead, they use a high-pressure spray system to blast water through rotating spray arms. This movement provides the scrubbing power that removes food and sanitizes dishes, all with a surprisingly small amount of water. A typical wash cycle uses only 6 to 10 gallons of water, depending on your model and settings. The dishwasher fills and drains several times during each cycle, flushing out dirty water and replacing it with clean water for rinsing.

Are Gel Pods or Gel Detergents Bad for Your Dishwasher?

Gel-based detergents (including liquid gels and some pods) are popular for their convenience and low cost, but they’re not always the best choice, especially if you’re dealing with:

• Hard water
• Dull or spotted dishes
• Poor cleaning performance

Here’s why:

• Many gel detergents contain bleach, which can degrade internal rubber seals over time.
• Gels often don’t dissolve completely in cooler or shorter cycles.
• They can leave residue behind and may perform poorly in hard water conditions.

While some newer multi-chamber pods contain powder, liquid, and rinse agents all in one, basic gel pods or pure liquid gel detergents may not deliver the best results, especially if you’re troubleshooting performance issues. Try switching to a powdered detergent or an enzyme-based multi-layer pod, especially if your dishes aren’t coming clean.

Best Practices for a Cleaner Dishwasher Cycle

To get the best results, follow these simple dishwasher use and maintenance tips:

• Use hot water: The temperature should reach at least 130°F (54.4°C) to dissolve detergent, break down grease, and sanitize effectively.
• Fill both detergent cups if you have hard water.
• Use a rinse aid to reduce hard water spots and improve drying.
• Clean your dishwasher every 2 months by running a cycle with 2 cups of white vinegar and no dishes.
• Scrape (but don’t rinse) your dishes to prevent clogs and maximize cleaning efficiency.

If Your Dishwasher Still Isn’t Cleaning Well…

It’s not always the dishwasher’s fault. A few other things could be to blame:

Improper Loading

Overloading or incorrectly placing dishes can block spray arms and prevent proper water circulation. Pots, pans, and large bowls should never block the water jets. Try this test: Load your dishwasher half full and run a cycle. If dishes come out clean, overloading may be the problem.

Hard Water Problems

Hard water contains minerals like calcium and magnesium that make it tough for detergent to do its job.

Signs of Hard Water

• Cloudy glassware
• White spots on dishes
• Soap doesn’t lather well

Solutions:

• Use more detergent (about 50% more)
• Add 1 tablespoon of baking soda per load to soften the water
• Use a rinse aid consistently
• Consider installing a water softener if buildup becomes a serious issue

Cloudy Glass vs. Damaged Crystal

Cloudy glass can be caused by:

• Hard water deposits (removable)
• Etching from harsh detergents or high alkalinity (permanent)

Test for hard water clouding: Soak the glass in straight vinegar for 5 minutes. If it clears, the issue is mineral buildup.

To Fix and Prevent Cloudiness

• Increase detergent slightly
• Use a rinse agent
• Add baking soda if needed

Do not put fine crystal in the dishwasher. The high heat and alkaline detergent can permanently damage or “etch” the surface, making it appear cloudy.

When NOT to Use the Dishwasher

While modern dishwashers can clean more than just plates, some items are better washed by hand:

• Plastic parts from food processors: May warp or discolor over time, even if labeled dishwasher-safe
• Food processor and blender blades: Can dull or bend in the dishwasher
• Metal parts from small appliances (like hand mixers or can openers): May rust or have protective coatings that peel off

Occasional dishwasher use for these items may be okay, but hand-washing with soapy water is best for longevity.

Dishwasher Cleaning Do’s & Don’ts

Do:

• Use hot water (130°F)
• Load dishes properly and avoid blocking spray arms
• Use a rinse aid for hard water
• Clean your dishwasher regularly with vinegar
• Try powdered or enzyme-based detergents if gels underperform

Don’t:

• Use gel detergents if you have hard water or poor cleaning results
• Wash fine crystal or fragile plastics in the dishwasher
• Overload or nest items that prevent thorough cleaning
• Ignore signs of mineral buildup or soap scum

A dishwasher is one of the hardest-working appliances in your kitchen, but it needs a little help to keep running efficiently. If your dishes aren’t coming out clean, the issue could be as simple as the detergent type, water temperature, or how the dishes are loaded. By following these tips, avoiding common pitfalls, and reconsidering the use of basic gel detergents or pods, you can get back to sparkling clean dishes without the frustration.
