Let's face it—we're all looking for shortcuts in our cleaning routines. Between work deadlines, family obligations, and trying to squeeze in that show everyone's been talking about, who has time for scrubbing? Your dishwasher might just be the undercover superhero of your household, capable of far more than just removing last night's spaghetti sauce from your plates.

Think of your dishwasher as that overachieving friend who's always raising their hand to help. "I can do that too!" it seems to say, while you're elbow-deep in hand-washing items that could have been enjoying a spa-like experience alongside your dinner dishes.

So before you tackle your next deep clean, check out these seven surprisingly dishwasher-friendly items that have been patiently waiting for their turn in the magical cleaning box in your kitchen.

 

1. Kitchen Sponges and Brushes: The Tools That Clean Need Cleaning Too

We've all been there—reaching for that kitchen sponge that's been sitting by the sink for... how long exactly? You can't remember, but you're pretty sure it now qualifies as a science experiment.

These cleaning workhorses harbor more bacteria than you want to think about. According to studies, the average kitchen sponge can contain more bacteria than a toilet seat. Let that sink in for a moment (but not your sponge—that goes in the dishwasher!).

How to wash them: Place sponges on the top rack, preferably in a dishwasher basket or between the tines of a rack to prevent them from flying around during the cycle. For brushes, remove any wooden handles first—wood and dishwashers are not friends.

Why it works: The hot water and drying cycle kill most bacteria and refresh your sponges, extending their lifespan. While no cleaning method eliminates 100% of germs (short of incinerating the sponge, which defeats the purpose), the dishwasher's high temperatures make a significant dent in the microbial party happening in your sponge.

Pro tip: Even with regular dishwasher cleaning, replace your kitchen sponges every two weeks. Think of it as eviction day for the microscopic squatters.

2. Plastic Toys: Where the Germs of a Thousand Sticky Fingers Lurk

If you've ever stepped on a LEGO in the middle of the night, you know the unique pain that children's toys can inflict. But have you thought about the invisible threat they carry? Kids' toys—especially those beloved pieces that go everywhere, including mysterious puddles at the playground—are germ magnets.

My revelation came when my nephew's favorite dinosaur started looking less green from design and more green from... well, let's not think too hard about that.

How to wash them: Place small plastic toys in a mesh bag or dishwasher basket on the top rack. For larger toys, arrange them securely between the tines. Use a gentle cycle with no heated dry for anything with stickers or delicate features.

Why it works: The dishwasher sanitizes toys without you having to individually scrub each tiny crevice where goldfish cracker residue and playground dirt have formed an unholy alliance.

Pro tip: Not all toys are dishwasher candidates. Avoid washing anything with batteries, metal parts that might rust, painted details that could fade, or plush components. Always check the manufacturer's instructions and only wash toys specifically labeled as dishwasher-safe.

Word of caution: Those dollar store plastic toys might not survive the adventure. Do a test run with less precious items before committing the favorite toy that would cause a meltdown if damaged.

 

3. Baseball Caps: Restore Your Headwear Without Losing Its Shape

Remember when you bought that perfect baseball cap? The one that made you look like you belonged at a trendy rooftop bar or could actually throw a curveball? Now it's sweat-stained and smelling like a combination of hair products and last summer's barbecue.

Most people avoid washing caps for fear of ruining their shape—leading to the unfortunate phenomenon I call "hat monogamy," where you're stuck wearing the same grimy cap because all your others have been deformed by washing attempts.

How to wash them: Use a cap washing frame (yes, that's a real product) or improvise with a round bowl that fits inside the cap to maintain its shape. Place it on the top rack, away from direct spray that could dislodge it. Choose a gentle cycle with cold water and skip the heated dry.

Why it works: The dishwasher's gentle but thorough cleaning action removes oils and dirt without the agitation of a washing machine, which is what typically destroys a cap's structure.

Pro tip: This works best for newer caps made with synthetic materials and plastic brims. Vintage caps with cardboard brims should never see the inside of a dishwasher unless you're going for that melted Salvador Dalí aesthetic.

Word of caution: Opinions on dishwashing caps are divided. Some experts recommend hand washing instead to preserve the cap's shape and color. If your cap is particularly valuable or beloved, consider testing this method on a less important hat first or stick with gentle hand washing.

 

4. Refrigerator Shelves and Bins: Because Removing That Mystery Spill Shouldn't Require a Chisel

We've all played the game of "what's that sticky spot?" in our refrigerators. That moment when you remove a condiment bottle and it makes a sound like you're separating velcro. Or when the vegetable drawer has more liquid at the bottom than your water bottle.

Cleaning refrigerator components by hand is about as enjoyable as filing taxes—necessary but painfully tedious.

How to wash them: Remove glass shelves and plastic bins from your refrigerator. For glass shelves, make sure they're room temperature before washing (to prevent cracking) and place them carefully on the bottom rack with plenty of space between them. Plastic bins can go on the top rack. Use a gentle cycle without heated dry.

Why it works: The dishwasher's spray arms can reach all the nooks and crannies where spilled salsa from 2023 has been hiding, and the hot water dissolves even the most stubborn dried-on residue.

Pro tip: Before you start disassembling your refrigerator, take a quick picture of the interior setup. This saves you from the post-cleaning puzzle of "I have no idea where this shelf goes."

Word of caution: Check your refrigerator's manual first. Some manufacturers explicitly advise against dishwashing certain components, particularly if they have special coatings or electronic elements. Also ensure glass shelves are positioned away from heating elements to prevent thermal shock.

 

5. Silicone Bakeware and Oven Mitts: Because Scrubbing Baked-On Grease Is Nobody's Idea of Fun

Silicone kitchen items have revolutionized baking—until it's time to clean them. That non-stick miracle material somehow manages to develop a sticky film that seems impervious to regular washing. And silicone oven mitts? After a few spills and splashes, they can look like abstract art projects.

I once spent 20 minutes trying to scrub a silicone cupcake mold clean, only to still feel a greasy film when I was done. That was before my dishwasher epiphany.

How to wash them: Place silicone items on the top rack, making sure they're not touching the heating element. Only wash silicone products specifically labeled as dishwasher-safe. For oven mitts, check the manufacturer's care instructions—many newer silicone mitts are dishwasher-approved.

Why it works: The combination of hot water and dishwasher detergent cuts through the oil that bonds to silicone surfaces, which regular dish soap sometimes struggles to remove.

Pro tip: For especially greasy silicone items, give them a quick wipe with a paper towel before placing them in the dishwasher. This removes excess grease and improves cleaning results.

6. Range Hood Filters: The Forgotten Grease Collectors

If your kitchen has ever set off the smoke detector during a simple bacon-frying session, your range hood filter might be overdue for cleaning. These mesh screens are designed to catch grease particles before they circulate through your home, but they can only do their job effectively when they're clean.

Most people forget these filters exist until they're so clogged with grease that they resemble a prop from a horror movie.

How to wash them: Remove the metal mesh filter from your range hood (consult your manual if you're not sure how). Place it on the bottom rack of your empty dishwasher. Run a normal or heavy cycle with hot water.

Why it works: Dishwasher detergent is specifically formulated to break down food grease and oils—exactly what's coating your range hood filter. The high-pressure spray helps dislodge particles from the mesh.

Pro tip: For severely neglected filters, consider running them through two consecutive cycles. The first cycle will remove the bulk of the grease, while the second will tackle any remaining residue.

Word of caution: This trick works for metal mesh filters only. Charcoal filters or other non-metal types should never go in the dishwasher. Check your range hood's manual if you're unsure which type you have.

 

The Fine Print: What You Should NEVER Put in Your Dishwasher

Before you go on a dishwasher-loading spree, let's talk about what should stay far away from this appliance:

  1. Anything wooden: Cutting boards, utensils with wooden handles, and wooden salad bowls should all be hand washed. The dishwasher's heat and moisture will cause warping, cracking, and a shortened lifespan.

  2. Cast iron or carbon steel: Unless you enjoy the rusty look, keep these out of the dishwasher. You'll strip the seasoning and potentially ruin the pan.

  3. Good knives: Your expensive chef's knives deserve better than the dishwasher, which can dull blades and damage handles.

  4. Crystal or delicate glassware: The heat and force of the water can cause chips, cracks, or cloudiness.

  5. Anything with adhesives: Labels, glues, and certain types of tape can dissolve and clog your dishwasher's filter or spray arms.

  6. Electronics: Seems obvious, but in our gadget-filled world, it's worth mentioning that anything with a battery, plug, or electronic component should stay dry.

 

Dishwasher Loading 101: The Art of Getting Things Actually Clean

Now that you've expanded your dishwasher horizons, let's talk strategy. Even the most dishwasher-friendly items won't get clean if loaded incorrectly:

  • Don't overcrowd: Items need space between them for water to circulate. An overpacked dishwasher is an ineffective dishwasher.

  • Mind the spray arms: Ensure nothing blocks their rotation, or you'll end up with spots that never see water.

  • Consider water flow: Place the dirtiest surfaces facing the spray arms (usually downward for the top rack, inward for the bottom).

  • Secure lightweight items: Use dishwasher baskets or place small items between tines to prevent them from becoming dishwasher projectiles.

  • Use the right detergent: Not all dishwasher soaps are created equal. For non-traditional items, consider a gentle formulation.
