Step 1 – Empty The Block And Make A Cleaning Solution

Start by removing the knives (and any other contents) from your knife block and washing them by hand. Once the block is empty, turn it upside down over your garbage can or sink and shake it to remove any loose dust or debris.

To disinfect the inside of the block, make a simple bleach solution by adding 1 teaspoon of bleach to 1 quart of warm water. You’ll also need a few pipe cleaners, a sponge or scrub brush, and a clean, dry cloth.

Step 2 – Clean Each Slot With A Pipe Cleaner

Pipe cleaners are the perfect tool for cleaning out those deep, narrow slots, and they’re widely available and inexpensive. Start by dipping a pipe cleaner into the diluted bleach solution, then insert it into a slot and give it a good scrub.

Rinse or replace the pipe cleaners as needed until each of the slots in your knife block has been cleaned and sanitized.

Step 3 – Clean The Exterior

Next, clean the exterior of the block using a sponge and warm, soapy water. Use a clean, damp cloth to remove the soap residue and loosened gunk from the outside of the block.

Step 4 – Let It Dry

Use a clean towel or cloth to pat the block dry, then leave it out on your countertop to dry for several hours (or overnight). It’s important to let the wood dry completely before using it again!

Step 5 – Replace The Knives

Once the block is bone-dry, carefully replace the knives. Then pat yourself on the back for a job well done!

“Thank you so much for this reminder to clean my knife block, something that hadn’t crossed my mind! As for replacing the knives, I was told long ago to store my knives with the blade facing up. That way they would not [rub] the wood surface each time you inserted or removed them.”
