Stop making these common dishwashing mistakes today
We all want sparkling clean dishes, but let’s face it - most of us are making simple dishwashing mistakes that ruin our plates, glasses, and even our appliances. Whether you're a handwasher, a dishwasher devotee, or somewhere in between, you're probably not doing things as efficiently or hygienically as you think.
From improper loading techniques to poor maintenance and downright dirty habits, it's time to stop these dishwashing blunders once and for all. We’re breaking down the worst dishwashing mistakes you might be making - plus, we’ll share the smarter habits you can start using today for cleaner, longer-lasting dishes and a happier kitchen.
1. The Dirty Truth About Dishwashing Habits
Why most people get dishwashing wrong
It’s easy to think that washing dishes is foolproof, but in reality, a lot of people are doing it wrong without even knowing. Common issues stem from bad habits formed over the years, like rushing through the process, relying too heavily on machines, or not understanding how detergents and water temperature affect cleanliness. Even something as simple as stacking dishes incorrectly can prevent them from being properly cleaned.
We also tend to overlook the hygiene side of things. Reusing sponges too long, letting food particles build up, or assuming a dishwasher handles everything can leave your dishes dirtier than before. These habits don’t just waste time; they can lead to bacterial buildup and permanent damage to your cookware.
The difference between handwashing and dishwasher use
There’s a big difference between washing dishes by hand and using a dishwasher, and each has its pros and cons. Handwashing gives you control over each item and works well for delicate cookware, but it’s often done with lukewarm water and old sponges, which aren’t great for killing bacteria. Dishwashers, on the other hand, use hotter water and are better at sanitizing, but only if used correctly.
Many assume the dishwasher will clean anything, but overloading it or skipping maintenance means you're just moving grime around. Likewise, handwashing with improper technique—like rinsing before scrubbing or letting dishes sit too long—can be just as ineffective. Knowing when to use which method is key.
How bad habits lead to germ spread and dish damage
If you’re not washing dishes correctly, you’re not just leaving behind a few crumbs—you’re inviting bacteria to the party. Old sponges, dirty dishwashers, and food residue are all breeding grounds for germs. These microbes can cling to utensils and plates and make their way into your next meal.
On top of that, bad habits like using the wrong tools, not rinsing thoroughly, or using abrasive materials can damage your dishes. Over time, this causes cloudy glassware, scratched nonstick surfaces, and rusting on utensils. Your dishes will wear out faster, and your meals may not be as safe or enjoyable to eat from.
2. Common Mistakes That Damage Your Dishes
Overloading the dishwasher and why it’s a problem
Overloading the dishwasher is one of the most common and damaging mistakes out there. When you cram dishes into every nook and cranny, you restrict water and detergent from reaching everything evenly. That means half of your dishes might come out still dirty or streaked with food residue.
It also causes dishes to bump into each other during cycles, leading to chipping, cracking, or scratching, especially with glassware. Not only are you risking your plates and glasses, but you’re also overworking your dishwasher, which can lead to long-term damage. Always leave enough space between items, and follow your dishwasher’s loading guidelines.
Using the wrong detergent or too much of it
It’s tempting to think that more detergent means cleaner dishes, but that’s far from the truth. Using too much dishwasher detergent can leave behind a filmy residue, especially on glass and plastic items. It can also cause a buildup in your machine, which affects its performance over time.
Handwashing with the wrong type of soap, like dishwashing liquid in the dishwasher or using harsh chemicals, can also be problematic. Not only do the wrong detergents damage your dishes, but they can also be harmful to your skin and create unnecessary waste. Always match the detergent to the task and use only the amount recommended.
Not scraping or pre-rinsing dishes properly
While many modern dishwashers are designed to handle some leftover food, that doesn’t mean you should toss in a plate covered in sauce or crumbs. Not scraping or pre-rinsing dishes properly can clog filters, gum up spray arms, and reduce cleaning efficiency.
You don’t need to scrub your plates spotless before loading, but a quick rinse under hot water or a firm scrape with a rubber spatula can go a long way. This ensures your dishwasher runs smoothly and helps prevent lingering smells and bacterial buildup inside the machine.
3. Dishwasher Maintenance Errors You’re Probably Making
Ignoring filter cleaning and its gross consequences
One of the easiest ways to ruin a perfectly good dishwasher is to ignore the filter. Most people don’t even realize there’s a filter that needs cleaning, but trust us—it’s there, and it’s probably disgusting. The filter traps food particles and debris, and if it’s not cleaned regularly, it can get clogged, smell awful, and cause dishes to come out dirty.
When a filter is clogged, it restricts water flow and makes your machine less effective. Worse, you might see leftover gunk or even mold growth inside the dishwasher. Cleaning the filter once every week or two is a simple task that keeps your dishes and dishwasher fresh.
Skipping regular deep cleans of your machine
Your dishwasher might clean your dishes, but who’s cleaning the dishwasher? Skipping regular deep cleans can lead to a buildup of grime, detergent residue, and even limescale. These buildups can make your dishwasher smell bad and underperform.
Every month or so, it’s a good idea to run an empty cycle with a dishwasher cleaner or a mix of vinegar and baking soda. This clears out hidden gunk, removes mineral deposits, and keeps the interior looking and smelling fresh. Don’t forget to wipe down the door seals and spray arms, too.
Loading items in the wrong rack every time
Believe it or not, where you place your dishes in the dishwasher matters—a lot. Putting items in the wrong rack can lead to poor cleaning, water spots, or even damage to both your dishes and the machine. For example, cups and lightweight plastics belong on the top rack, while pots and plates go on the bottom.
Utensils should be placed in the designated holder with handles down (except for knives—blades down for safety), and mixing materials (like glass and metal) can sometimes cause corrosion or etching. Taking a few seconds to load things properly ensures a more thorough clean and protects your kitchenware in the long run.
4. Handwashing Mistakes That Waste Time and Energy
Using water that’s too cold or too hot
Water temperature matters more than you might think when handwashing dishes. Cold water doesn’t effectively cut through grease or kill bacteria, while overly hot water can cause burns and isn’t always necessary. The ideal range is warm water—hot enough to cut through grime but safe for your hands.
Using the wrong temperature can also cause damage to certain dish materials, like delicate glassware or plastic. Cold water can leave an oily residue, and too-hot water can warp or crack items. Pair the right water temperature with a quality soap for the best results.
Reusing dirty sponges without thinking
Sponges are one of the dirtiest items in your kitchen. They soak up food particles, bacteria, and moisture, making them the perfect breeding ground for germs. Reusing a dirty sponge to “clean” your dishes just smears bacteria around—it's like washing your plates with a petri dish.
Replace your sponge every week or two, and sanitize it daily with a microwave zap or a soak in boiling water or vinegar. Even better, switch to dish brushes or silicone scrubbers that are easier to clean and don’t trap bacteria the same way.
Not washing in the right order (yes, that’s a thing)
Did you know there’s a proper order to wash dishes by hand? Starting with greasy pans or dirty plates can make your wash water grimy before you even get to the delicate stuff. The right method is to wash from cleanest to dirtiest—glassware, then silverware, then plates, and finally pots and pans.
This keeps your water clearer longer and reduces the spread of grease and food bits. It also protects fragile items from scratches or breakage. Getting into the habit of following a logical wash order saves time, keeps things cleaner, and reduces your water usage, too.
5. Smarter Habits for Sparkling, Germ-Free Dishes
Choosing the right dish tools for the job
Using the right dishwashing tools can make a big difference in both cleanliness and efficiency. Sponges, brushes, scrapers, and cloths all have different strengths, and choosing the right one for the task at hand is key. For example, a good scrub brush works well on pots, while a soft sponge is better for glasses.
Investing in high-quality tools that are easy to clean and dry quickly also reduces the risk of bacterial buildup. Tools with antimicrobial properties or detachable heads that can go in the dishwasher are even better. Keep a variety of tools nearby so you're never stuck scrubbing a pan with a rag meant for drying.
Setting the dishwasher to the optimal cycle
It’s tempting to always run the same dishwasher cycle, but not every load is the same. Using the right dishwasher setting ensures your dishes come out clean without wasting energy or water. Heavily soiled pots may need the heavy-duty cycle, while a half-load of glassware is fine on eco-mode.
Avoid the quick wash setting unless dishes are lightly used, and always use the heated dry if you want spotless, streak-free results. Most modern dishwashers also have sensor technology, so let them do their job. Don’t interrupt or open the door mid-cycle unless necessary—it just lets out heat and steam that your dishes need to dry properly.
Creating a simple post-meal cleaning routine
One of the best ways to avoid a mountain of dirty dishes is to clean as you go. A simple post-meal routine—like scraping plates immediately, rinsing utensils, and soaking pots—makes a huge difference. It also helps prevent food from drying onto dishes, which saves time later.
Encourage everyone in the household to get into the habit. Load the dishwasher as you cook, wipe down counters while things bake, and tackle dishes after dinner instead of letting them sit overnight. Consistency turns this routine into second nature, and your kitchen will always look cleaner.
Conclusion
We all want a cleaner, more efficient kitchen, and it starts with breaking bad dishwashing habits. Whether you’re a fan of scrubbing by hand or letting the dishwasher do its thing, avoiding these common mistakes can protect your dishes, save time, and even improve your health. From proper loading and rinsing to using the right tools and routines, every small step adds up. Ditch those dirty habits today—and make your dishwashing game strong, smart, and sanitary.
