Tech Items in the Dishwasher: What’s Actually Safe?

No—most tech items should not go in a dishwasher, even if they look like simple plastic accessories. Dishwashers combine hot water, detergent, forceful spray and a long wet cycle; only a few non-electronic, explicitly dishwasher-safe parts are reasonable candidates, and a device maker’s care instructions should decide the question.

Why a dishwasher is rough on technology

A dishwasher is designed to clean durable cookware, not to protect delicate materials or electronics. During a cycle, items may face hot water, powerful jets, alkaline detergent, drying heat and repeated contact with dishes or racks. A dishwasher-safe symbol on a food container does not mean that a similarly shaped tech accessory can tolerate the same treatment.

Water is only part of the problem. Detergent can strip coatings, cloud clear plastics, fade printed labels and attack finishes. Heat can soften adhesives, warp thin parts or damage batteries. Spray can force water into seams that might survive a quick splash, while prolonged moisture can remain trapped after the cycle ends.

Even an item that still turns on afterward may have suffered damage. Corrosion and residue can cause problems later, and a machine’s normal drying cycle may heat the item again after it has already been soaked.

Which items might be safe?

Consider the item’s construction, not just its name. A removable, plain-plastic accessory with no electronics, metal contacts, adhesive, coating or delicate finish may be suitable only if its manufacturer specifically says it is dishwasher-safe. For example, some removable plastic covers or organizers may carry care instructions that permit dishwasher cleaning. That permission applies to the specific part, not automatically to the phone, controller or other device it fits.

Items that might look like candidates include a bare plastic stand, a removable accessory shell, or a cable-management piece. But these are not safe by category: plastics vary, and one shell may be rigid and heat-tolerant while another is coated, glued or prone to warping. Check the product’s instructions or support information before washing it.

Potentially suitable: a separate, non-electronic part that the manufacturer explicitly labels dishwasher-safe, placed as directed.
Not suitable: anything with a battery, circuit board, connector, speaker, microphone, screen, motor or charging contacts.
Uncertain: unmarked plastic, coated parts, adhesive-backed accessories and anything with seams. Use a gentler cleaning method instead.

When instructions are missing, the safe assumption is that the item is not dishwasher-safe. “Water-resistant” is not the same as “dishwasher-safe”: resistance claims are tied to particular test conditions and do not establish tolerance for detergent, heat, pressure or a full wash cycle.

What should never go in

Keep phones, tablets, laptops, earbuds, headphones, smartwatches, cameras, game controllers, remote controls and chargers out of the dishwasher. These contain electronics, openings, batteries or sensitive materials. Do not wash cables or power adapters either; their insulation, plugs and internal components are not intended for immersion and machine drying.

Small accessories can be just as vulnerable. USB drives, memory cards, wireless receivers, styluses, tracking tags and removable battery packs may have exposed contacts or internal components. A sealed appearance does not prove that a product can withstand a dishwasher cycle.

Also avoid putting silicone or rubber accessories in the machine unless their own instructions allow it. Some may tolerate heat, but others can deform, retain detergent or have glued parts. A dishwasher-safe label on one material does not certify every component assembled into the accessory.

Safer ways to clean tech accessories

For most accessories, start with the least aggressive method allowed by the manufacturer. Disconnect the item from power and remove it from the device. If it has a removable battery, follow the maker’s instructions rather than improvising. Use a soft, dry cloth first; for grime, use a slightly damp cloth only if the product guidance permits it. Keep liquid away from ports, openings and seams, and do not spray cleaner directly onto the item.

Wipe a hard, non-electronic accessory with a soft cloth, using a small amount of water if its instructions permit.
For a fabric or silicone part, follow its specific cleaning directions; some should be hand-washed and fully air-dried.
Use a dry, soft brush to lift dust from crevices without pushing debris into ports.
Let cleaned parts dry completely before reconnecting or storing them. Do not use a dishwasher or high heat to speed drying.

Cleaning products can also cause damage. Alcohol, solvents, abrasive pads and household sprays may harm screen coatings, painted surfaces, rubber or adhesives. Do not assume that a product safe for one phone or accessory is safe for another; check the device maker’s guidance, especially for screens and coated surfaces.

If something has already been washed

If a tech item went through a dishwasher cycle, switch it off if you can do so safely and disconnect it from power. Do not charge it, turn it on to test it, or use heat to dry it. Remove detachable parts only if the instructions allow, then dry the outside gently and leave the item in a dry, ventilated place. Because detergent and moisture can remain inside, surface dryness is not proof that it is safe to use.

For an item with a battery or electronics, contact the manufacturer or a qualified repair service for guidance. Do not open a sealed battery or device unless the manufacturer’s repair instructions specifically permit it. If a battery is swollen, unusually hot, leaking or damaged, stop handling it and follow the manufacturer’s safety guidance; do not charge or reuse it.

How to judge a “dishwasher-safe” claim

Look for instructions that apply to the exact model and exact removable part. If the label says only “water-resistant,” “washable” or “easy to clean,” do not interpret that as permission for a dishwasher. The wording and care symbols matter, and instructions may distinguish between hand washing, top-rack placement and avoiding heated drying.

If the manufacturer does permit dishwasher cleaning, follow its conditions precisely. Remove electronics and batteries first if directed, use the specified rack, and avoid changing the cycle or drying method. Do not add a part to the machine simply because another accessory made from similar-looking plastic survived a wash.

Frequently Asked Questions

Can I put a phone case in the dishwasher?
Only if the case maker explicitly says that the specific case is dishwasher-safe. Many cases have coatings, adhesives or materials that may warp or degrade, so hand cleaning according to the care instructions is the safer default.

Can I wash a keyboard or game controller in the dishwasher?
No. Keyboards and controllers contain electronics and openings that can trap water and detergent. Clean their exterior with a dry cloth or the method their manufacturer recommends.

Does water-resistant mean dishwasher-safe?
No. Water resistance does not establish protection against hot water, detergent, forceful spray or extended drying. Use only the care method specified for the item.

Can a plastic accessory go on the dishwasher’s top rack?
Top-rack placement does not make an accessory safe. Use the dishwasher only when the manufacturer explicitly approves it and follow any rack or cycle instructions.

What if my electronic device still works after a dishwasher cycle?
Do not treat that as proof it is undamaged. Moisture or detergent may remain inside and cause later failure. Keep it off and unplugged, do not charge it, and ask the manufacturer or a repair professional what to do.
