Introduction
The short answer is usually no. Can you wash scissors in the dishwasher? Only when the manufacturer specifically says the entire tool is dishwasher-safe. Most household, craft, office, and garden scissors should be washed by hand, even when the blades are made from stainless steel.
A dishwasher exposes scissors to prolonged moisture, detergent, high heat, and impact from other items. Those conditions can corrode the blades, loosen pivots, discolor or warp handles, and make carefully aligned blades feel dull. Fortunately, proper hand cleaning usually takes only a few minutes.

Why Dishwashers Can Cause Problems
Dishwashers clean dishes effectively, but scissors are not designed like cutlery. A blade must remain straight, its edge must be precisely aligned with the opposing blade, and the pivot must move smoothly without excessive play. A cleaning cycle can interfere with all three requirements.
Water and detergent remain trapped between the blades and inside the joint. Heat from the wash or drying cycle then encourages that moisture to remain against the steel. The blades may strike racks and utensils during agitation, knocking the edge out of alignment or bending the tips. Cleaning compounds can also collect near the cutting edge, making the scissors feel blunt even when they are only dirty.
Heat may also affect the handle. Plastic can soften, discolor, or become brittle. Adhesive used to assemble resin handles can weaken, while screws or rivets may loosen as different materials expand and contract at different rates. These are the reasons a tool should never be placed in a dishwasher based solely on the appearance of its metal blades.
Scissor Types and Their Care Requirements
Different scissors react differently, but a dishwasher is appropriate only when all components, including the handles, joint, and any removable pieces, are approved for machine washing.
- Kitchen shears: These may have stainless blades, plastic grips, or multiple parts. Hand washing is the safest default because food residue, adhesives, and pivot lubricants can be affected by a dishwasher cycle.
- Household and office scissors: These are especially unsuitable for dishwashers. Heat and detergent can damage the finish, while impacts can distort the pivot and cutting edge.
- Craft and fabric scissors: Precision edges and carefully adjusted alignment can be damaged by impact, corrosion, or an embedded piece of detergent.
- Garden and pruning shears: Sap, soil, and natural oils require careful cleaning, but chemical residues and high heat may accelerate corrosion. Some tools contain springs or replaceable components that are not machine-safe.
- Utility shears: A small number of heavy-duty models are specifically designed and labeled for dishwasher use. That exception does not apply to all stainless-steel utility shears.
- Electric or battery-powered scissors: Never place these in a dishwasher. Water, detergent, and heat can damage the electrical system and may create a safety hazard.
“Stainless steel” describes corrosion resistance, not dishwasher safety. Even stainless steel can stain or corrode under harsh, prolonged conditions.
Why Manufacturer Guidance Matters
Check the handle, packaging, product insert, or official product page for a dishwasher-safe instruction. If the scissors are part of a set, look for the model number rather than relying on a general statement about the product line. The manufacturer may specify an upper-rack position, a particular cycle, or hand washing only.
When no instructions are available, assume that the complete tool requires hand washing. A lack of visible corrosion or a stainless blade does not prove that repeated machine washing is safe. If the tool is expensive, recently sharpened, antique, or difficult to replace, avoiding an unapproved cycle is the most practical choice.
What the Dishwasher May Damage
Potential damage depends on the scissor design, steel composition, handle materials, and cycle selected. The main risks include:
- Corrosion or staining: Detergent residue, minerals, and prolonged dampness can leave dark marks or surface rust, particularly on carbon steel.
- Dulling: The edge does not usually become blunt simply from water alone. However, impacts, misalignment, corrosion pits, and dried food or detergent can make an edge feel dull or cause it to drag.
- Heating and discoloration: A heated drying cycle may change the appearance of coated blades, discolor metal, or soften certain plastics.
- Handle failure: Resin handles may crack, separate, or lose adhesive. Handles containing different metals or plastics can loosen as they expand unevenly.
- Pivot damage: Bumping against other utensils can make a tight pivot loose or force the blades out of alignment.
- Component loss: Removable washers, tension springs, covers, or small parts may fall out and be damaged or lost.
- Premature wear: A damaged coating exposes steel more quickly, while a corroded pivot increases the force needed to operate the scissors.
One cycle may not cause visible harm, but it is not a reliable test. A tool can appear fine immediately and perform poorly later.
Cleaning Method Comparison
| Cleaning method | When to use it | Main advantage | Main caution |
|---|---|---|---|
| Brief hand washing | Most household, kitchen, craft, and garden scissors | Controls moisture and protects the edge, pivot, and handles | Do not soak the tool or leave it wet |
| Damp-wipe cleaning | Frequent light cleaning between deeper washes | Fast and suitable for blades without stuck residue | May not remove food trapped around the pivot |
| Manufacturer-approved dishwasher cycle | Only when the whole tool is labeled dishwasher-safe | Convenient for tools designed to tolerate the cycle | Follow rack position and cycle instructions exactly |
| Unapproved dishwasher cycle | Not recommended | Possibly removes heavy soil | Can cause corrosion, finish damage, or loss of alignment |
| Long soak | Generally unsuitable | Can loosen baked-on residue | Trapped moisture may attack the pivot and cutting edge |
Step-by-Step Hand-Washing Guide
Use this process for scissors that are not specifically labeled dishwasher-safe. Cleaning them promptly is especially important after cutting food, plant material, tape, or dirty packaging.
- Check before cleaning. Look for removable guards, locks, or tension components. Note how they are positioned so they can be reinstalled correctly.
- Remove loose residue. Wipe each blade with a soft cloth dampened with warm water. Use a soft toothbrush around the pivot and inner joint rather than forcing a stiff brush into the narrow space.
- Prepare mild soapy water. Fill a basin with lukewarm water and a small amount of mild dish soap. Avoid abrasive cleaners, bleach, oven cleaner, and strong solvent-based products.
- Clean the blades and joint. Open and close the scissors slowly while wiping the opposing surfaces. Pay attention to the pivot, screw heads, and the narrow area near the tips. Do not bend the blades to reach trapped debris.
- Rinse carefully. Wipe the tool with a clean, damp cloth or hold only the handle under cool running water. Avoid directing water into the joint unless residue cannot be removed otherwise.
- Dry immediately. Pat the blades dry with a soft, lint-free cloth, then separate the blades slightly and allow the joint to air-dry fully. Do not store the scissors in a closed drawer while they remain damp.
- Restore smooth operation. Once completely dry, place a tiny drop of light machine oil on the pivot if permitted by the manufacturer. Wipe away excess oil so it cannot collect on the blades or cutting surface.
If the scissors are used for food, clean and dry them after every use. Store them separately from raw meat, cleaning products, and other tools that could contaminate the handles or blades.
When Dishwasher Use May Be Safe
Some commercial or consumer kitchen shears are deliberately designed with corrosion-resistant steel, sealed handles, and durable construction. If the manufacturer states that they are dishwasher-safe, machine washing may be convenient. Follow any specified cycle, rack position, and loading instructions.
When loading approved scissors, place them where they cannot strike heavy pans or become wedged between dishes. Keep sharp points from striking the rack, and do not put loose components in the machine unless the manufacturer explicitly approves them. Avoid a heated drying cycle when the instructions advise against it.
Inspect the tool after every wash. Watch for staining, loose screws, stiffness, misalignment, or a weakened handle. Stop using the dishwasher if any of these appear, even if the product was originally labeled dishwasher-safe.
Restoring Dull or Sticky Blades
Blunt scissors are not always dull scissors. If food or fabric sticks and drags, the blades may simply need cleaning, the pivot may be too tight, or the blades may no longer overlap correctly. Cleaning and aligning the tool should come before sharpening.
After cleaning, test the scissors on a thin sheet of clean paper. A properly aligned pair should make a reasonably continuous cut. If it snags, tears, or needs excessive pressure, check that the screw or pivot is tight but not over-tightened. The blades should close fully without the handles touching.
To sharpen clean, dry household scissors, use a scissor sharpener designed for the type of blade. Follow its angle guides and make several light, even passes rather than forcing a heavy stroke. A knife sharpener can create an incorrect bevel and shorten the life of the scissors. Some specialty shears require a different sharpening system, so professional servicing may be more appropriate.
Do not sharpen rusty, deeply pitted, bent, or cracked blades. If the pivot is loose, one blade is sharper than the other, or the tips overlap incorrectly, replacement may be safer and more economical than attempting a repair. For expensive professional shears, consult the manufacturer or a qualified sharpening service.
Removing Light Surface Rust
Light surface rust does not always mean the scissors must be discarded, but it should be treated before sharpening. Stop using the tool if the rust is deep, the blade feels rough, the tips are bent, or the steel is flexing or cracking.
Wash and dry the scissors, then use very fine metal polish or a rust-removal product approved for the blade finish. Work along the cutting area with a clean cloth, keeping the product away from the pivot and handle. Rinse according to the product instructions, dry thoroughly, and remove every trace of abrasive residue.
A diluted white-vinegar treatment may help loosen some light rust, but it must be rinsed immediately and followed by complete drying. Vinegar is acidic and is not a routine cleaning solution. Do not combine it with bleach or other cleaners.
Once dry, apply a very light coating of corrosion-inhibiting oil to the bare cutting surfaces and pivot. Wipe off the excess. If rust returns quickly, the steel may already be pitted, or the environment is too corrosive for the tool. Replacement is usually more reliable.
Common Mistakes to Avoid
- Assuming stainless steel means dishwasher-safe: Stainless steel resists rust but can stain, pit, or lose its finish under prolonged chemical and heat exposure.
- Leaving the scissors submerged: Soaking allows water to collect around the pivot, screw holes, and blade edges. Cleaning and prompt drying are safer.
- Adding detergent to the joint: Residue can make the pivot stiff and gritty. Apply cleaner with a controlled stream or damp cloth.
- Storing wet blades: Moisture trapped between the blades encourages corrosion. Separate the blades and dry the joint before storage.
- Sharpening before cleaning: Dirt and grit can act like abrasive material and damage the edge. Remove residue and dry the scissors first.
- Over-tightening the pivot: Excess tension can misalign the blades, create uneven wear, and make operation difficult.
- Oiling the cutting edges: Oil belongs on the pivot, not between the cutting surfaces. Excess oil attracts dirt and must be wiped away.
- Using damaged scissors: Loose, bent, cracked, or badly corroded blades can slip, leave uneven cuts, or cause injury. Replace them when the problem cannot be corrected safely.
- Disinfecting indiscriminately: Bleach, alcohol, and chemical sanitizers may damage adhesives, coatings, or plastic. Use them only when the manufacturer approves the method.
Cleaning and Storage Best Practices
- Give every scissor set one clearly stated cleaning method, usually hand washing unless the product is labeled otherwise.
- Use mild soap, lukewarm water, a soft cloth, and a soft brush. Abrasive pads and metal scouring pads can scratch the finish and edge.
- Wipe from the pivot toward the tips so debris is not pushed deeper into the joint.
- Open the blades during drying, then close them only when the joint is completely dry.
- Store dry scissors in a clean drawer or sheath. Avoid loosely tossing them with tools that can strike the cutting edge.
- Keep food and garden scissors separate. This reduces contamination, staining, and cross-contact.
- Use cutting boards rather than hard countertops, which dull edges and bend blade tips.
- Oil light-duty pivot points periodically when they become stiff, following the tool manufacturer’s guidance.
- Replace scissors that no longer cut cleanly, develop cracks, or lose alignment. A correct cleaning routine cannot restore damaged steel.
Frequently Asked Questions
Can you wash scissors in the dishwasher?
Only if the manufacturer explicitly says the complete tool is dishwasher-safe. For unlabeled household scissors, hand washing is the recommended method. Dishwasher heat, detergent, moisture, and impacts may damage the blades, finish, handles, or pivot.
Are stainless-steel scissors dishwasher-safe?
Not automatically. Stainless steel is more corrosion-resistant than ordinary carbon steel, but it is not immune to staining, pitting, or damage from harsh detergent and high heat. Look for a dishwasher-safe label or model-specific instructions instead of deciding from blade material alone.
Will one dishwasher cycle ruin my scissors?
One cycle does not necessarily ruin them, but it can create problems that are not immediately visible. A blade may develop residue or corrosion, or the pivot may move slightly out of alignment. If a valuable or well-sharpened pair is not approved for machine washing, the risk is unnecessary.
Can dishwasher-safe scissors go on the top rack?
Only if their instructions specify the top rack. The top rack experiences less spray, but the scissors can still be struck by utensils or damaged during drying. Follow the stated rack position and loading method rather than assuming the top rack is always suitable.
Why do my scissors stick after washing?
Dried food, detergent residue, corrosion, or a tight pivot can cause sticking. Clean and dry the joint, then check the screw without over-tightening it. If the blades are clean but still scrape, the cutting edges may be misaligned, dull, or in need of professional sharpening.
Can I use scissors that have developed rust?
Very light surface rust can sometimes be removed, but stop using the tool if the corrosion is deep, the blade feels rough, or the tips are bent. Clean, dry, treat, and oil the steel thoroughly before considering sharpening. Repeated rust usually indicates that replacement is the safer option.
Conclusion
Can you wash scissors in the dishwasher? The answer depends on clear manufacturer approval, not on the fact that the blades are metal. Unless the entire tool is labeled dishwasher-safe, wash it briefly by hand, remove residue around the pivot, and dry it immediately.
This simple routine protects the cutting edge, alignment, finish, and handles. Check scissors that drag or lose sharpness for dirt and pivot problems before sharpening them, and replace any tool that is deeply corroded, cracked, bent, or loose. For most household scissors, careful hand cleaning is the safest and most economical long-term care method.
