How to Clean and Maintain Kitchen Knives (2026 Guide)

TL;DR — Hand-wash knives immediately after use with warm soapy water, dry them right away, never put them in the dishwasher, hone regularly, sharpen occasionally, cut only on wood or soft plastic, and store them so edges don’t touch other metal. These habits keep knives sharp, safe, and lasting for decades. The HomeWhisk team compiled this from care guidance and aggregated feedback. Good knife care is mostly about washing, drying, and storage — the unglamorous basics. For picks, see our best chef knife guide.

Good knives are an investment, and proper care keeps them sharp, safe, and lasting for years — even decades. The habits are simple but easy to get wrong. Here’s how to clean and maintain your kitchen knives properly. For choosing knives, see our best chef knife guide.

Cleaning: The Right Way

How you wash a knife affects its edge, its finish, and your safety. Here are the rules.

Hand-wash, never the dishwasher. This is the most important cleaning rule. The dishwasher damages knives multiple ways: the harsh detergent and heat corrode and dull the blade, knives knock against other items (chipping edges), and the moisture and heat can damage handles (especially wood). Always hand-wash knives — it takes seconds and protects your investment.

Wash immediately after use with warm water, mild dish soap, and a sponge or cloth. Don’t let food (especially acidic, salty, or sticky residue) sit on the blade, which can stain or corrode it, particularly on carbon steel.

Wash safely: wipe the blade from spine to edge (never run your fingers along the sharp edge), holding the handle. Clean one knife at a time — never leave knives submerged in a sink of soapy water where you (or someone else) can’t see them and could reach in and get cut. This is a real safety issue.

Dry immediately and thoroughly with a towel, wiping spine-to-edge. Don’t air-dry or leave knives wet — standing water causes spotting, and over time corrosion and rust, even on stainless steel (which is stain-resistant, not stain-proof). Carbon steel especially must be dried at once.

For stuck-on residue, soak the blade briefly in warm water (don’t leave it long), then wipe. Avoid abrasive scrubbers on polished blades.

Hand-wash, wash promptly and safely, dry immediately — these basics prevent most knife damage. Our best chef knife guide covers knives worth caring for this way.

Keeping the Edge: Honing and Sharpening

A knife’s whole purpose is its edge, and two distinct practices keep it sharp. Confusing them is the most common maintenance mistake.

Honing (frequent) realigns the edge. As you cut, the thin edge folds and rolls slightly, making the knife feel dull though the metal is still sharp. Honing with a steel straightens it back — it removes no metal and takes seconds. Hone every use or two. This is the everyday step that keeps a knife feeling sharp. See our honing guide for technique.

Sharpening (occasional) grinds a new edge. When honing no longer restores sharpness, the metal is genuinely worn and needs sharpening on a whetstone or sharpener to form a fresh edge. Because it removes metal, do this only occasionally — every few months to once a year for home use. See our sharpening-frequency and whetstone guides, and our best knife sharpener guide for tools.

The rule: hone often, sharpen rarely. Most people who think their knife needs constant sharpening actually need honing.

Why it matters for safety: a sharp knife is safer than a dull one — it cuts predictably with less force, so it’s less likely to slip. Keeping knives sharp isn’t just about performance; it prevents accidents. A dull knife is the dangerous one.

Test sharpness with the paper test (slice a sheet — clean cut = sharp) or tomato test (bites the skin easily = sharp). If it snags or slips after honing, it’s time to sharpen.

Cutting Surfaces and Storage

Two habits outside of cleaning have huge effects on how long a knife stays sharp: what you cut on and how you store it.

Cut only on wood or soft plastic — never glass, stone, marble, or ceramic. Hard surfaces destroy knife edges on contact, dulling and chipping them with every cut. A cutting board should be softer than the knife. Wood (especially end-grain) is gentlest; quality plastic is fine. A glass board undoes your sharpening in days. This single habit hugely affects edge life. See our cutting-board guides.

Also avoid cutting on countertops, metal, or plates, and don’t use a fine kitchen knife on bones or frozen food (that chips the edge — use the right tool).

Store knives so edges don’t touch other metal or knock around. Loose in a drawer is the worst option — blades bang against other utensils and the drawer, dulling and chipping edges, and it’s a cut hazard when you reach in. Instead use:

• A knife block (edges protected in slots),
• A magnetic strip (blades held clear, place spine-first),
• An in-drawer knife tray (each blade separated),
• Or edge guards (sheaths) if you must keep knives in a drawer.

See our knife-storage and best knife block set guides. Proper storage protects both the edges and your fingers.

Keep knives dry in storage — store only fully dried knives, and ensure block slots stay dry (insert knives dry to prevent mold).

Right cutting surface, right storage — these protect the edge as much as sharpening does. Together with proper cleaning, they’re the core of knife care.

Frequently Asked Questions

Can I put my kitchen knives in the dishwasher?

No — never put good kitchen knives in the dishwasher. The harsh detergent and heat corrode and dull the blade, knives knock against other items and chip their edges, and moisture and heat damage handles (especially wood). This is the single most damaging thing you can do to a knife, and it’s completely avoidable. Always hand-wash knives with warm soapy water and dry them immediately. It takes only seconds and dramatically extends the life and sharpness of your knives.

How do I clean a kitchen knife properly?

Hand-wash it immediately after use with warm water, mild dish soap, and a sponge, wiping the blade from spine to edge (never along the sharp edge) while holding the handle. Wash one knife at a time — never leave knives hidden in a sink of soapy water, which is a cut hazard. Then dry it thoroughly right away with a towel, since standing water causes spotting and eventual corrosion, even on stainless steel. Don’t let food residue sit on the blade or use the dishwasher.

What’s the difference between honing and sharpening?

Honing realigns the edge, which folds and rolls slightly during use — it makes a knife feel sharp again, removes no metal, and should be done frequently (every use or two) with a honing steel. Sharpening grinds away metal to create a new edge when the blade is genuinely worn, and is done occasionally (every few months to a year) on a whetstone or sharpener. Hone often, sharpen rarely. Most people who think they need to sharpen constantly actually just need to hone. See our honing guide.

What should I cut on to protect my knives?

Only wood or soft plastic cutting boards — never glass, stone, marble, or ceramic, which are harder than the blade and dull and chip the edge with every cut. A cutting board should be softer than the knife so it gives slightly and cushions the edge. Wood (especially end-grain) is gentlest; quality plastic is fine. Also avoid cutting on countertops, plates, or metal, and don’t cut bones or frozen food with a fine knife. The right surface hugely extends edge life.

How should I store kitchen knives?

Store them so edges don’t touch other metal or knock around: a knife block, a magnetic strip (place blades spine-first), an in-drawer knife tray, or edge guards if you keep them in a drawer. Never toss knives loose in a drawer — they bang against other utensils, dulling and chipping edges, and it’s a cut hazard when you reach in. Store only fully dry knives to prevent corrosion and mold. Proper storage protects both the edges and your fingers. See our knife-storage guide.

Why is a sharp knife safer than a dull one?

Because a sharp knife cuts predictably with less force — it bites where you place it and glides through food. A dull knife requires more pressure and is prone to slipping off food, and that combination of extra force and unpredictable slipping causes accidents. So keeping knives sharp (through regular honing and occasional sharpening) isn’t just about performance — it’s a genuine safety measure. Counterintuitively, the dull knife in the drawer is the dangerous one, not the sharp one.

The Bottom Line

Kitchen knife care comes down to simple habits done consistently: hand-wash immediately with warm soapy water and dry at once (never the dishwasher), hone regularly to keep the edge aligned and sharpen occasionally when honing no longer helps, cut only on wood or soft plastic (never glass or stone), and store knives so edges don’t touch other metal — a block, magnetic strip, in-drawer tray, or edge guards. These unglamorous basics keep knives sharp, safe, and lasting for decades, and remember a sharp knife is the safe one.
