• Home cooks often take their knives for granted, but a knife block on the counter is a convenient way to store them.
• A knife block is a stable way to store knives, keeping them safe, easy to access, and easy to store.
• It’s not as obvious how to keep a knife block clean, and the importance of doing so is essential to maintaining your knives and preventing damage.

A knife block is a vital component of any home kitchen, but it’s often overlooked when it comes to cleaning and maintenance. While it’s easy to keep your knives sharp, it’s not as obvious how to keep your knife block clean and free from debris. We spoke to Henry Liu, founder and CEO of Cangshan Cutlery Co., and Alicia Sokolowski, green cleaning expert and president and co-CEO of AspenClean, to get the lowdown on keeping your knife block clean and safe. According to Liu, knife storage blocks can be difficult to clean because the narrow-slotted openings for the blades can be hard to reach. Food particles and moisture can get trapped inside, creating an environment where mold could potentially grow. Liu emphasizes that simply rinsing the block is not an option, as it can cause warping due to excess water. While it’s challenging to determine when a knife block needs cleaning, Sokolowski recommends cleaning it once a month to prevent buildup. However, if you frequently use and store damp knives, consider cleaning it more often. To clean a knife block, Sokolowski provides the following steps:

1. Empty the knife block: Remove all knives and set them aside.
2. Remove any debris: Use a vacuum nozzle to remove loose crumbs and dust inside the slots.
3. Wash the exterior: Use a damp microfiber cloth and mild dish soap to wipe down the outer surface.
4. Clean the slots: Mix warm water with a few drops of mild dish soap. Dip a small bottle brush into the soapy water and scrub inside each slot.
5. Disinfect the slots: Mix equal parts of white vinegar and water, then use to wipe the slots with a clean brush or cloth.
6. Wipe away any soap residue: Use a damp cloth to remove any soap.
7. Air dry: Let the block dry completely before reinserting the knives to prevent mold growth.

Sokolowski emphasizes that putting knives in the knife block only when they are clean and dry is the most important tip for keeping a knife block clean and sanitary. She notes that inserting damp knives encourages mold and bacteria growth inside the slots. If a less involved cleaning is needed, Sokolowski recommends using a bottle brush or pipe cleaner to reach deep into the slots for a thorough clean.

“A mild dish detergent effectively removes grease and grime without harsh chemicals, says Sokolowski. Alternatively, use white vinegar, which is great for deep cleaning and a natural disinfectant that helps kill bacteria. It’s also great for neutralizing odors, she says.”

Sokolowski also advises against using abrasive scrubbers, which may scratch and weaken the surface of the knife block over time. Instead, use a gentle touch when cleaning your knife block to maintain its integrity and longevity. What the Experts Want You to Know
