Short answer
Learn how to clean a utility knife by matching the method to the handle material, clearing the blade setting, and drying thoroughly before storage.
Short Answer: Match the Cleaning Method to the Handle
How you clean a utility knife depends mainly on the handle material. A wood handle can be cleaned with warm water to remove muck, then dried carefully and left to air-dry completely so moisture can evaporate from the wood. A polymer handle is designed to cope well with water and can go in the dishwasher.
The blade setting needs separate attention because dust, dirt, and other muck can accumulate inside it. Clean inside the blade setting with sandpaper folded in half or a compressed air blower.
Cleaning a Wood Handle Without Causing Damage
Warm water is enough to remove muck from a wood handle, but the drying stage matters just as much. Dry the handle carefully and leave it to air-dry completely so moisture can evaporate from the wood.
After the handle is dry, apply nourishing oil with a dry cloth and leave it to dry for a few hours before using the knife again. Oiling the handle can also revive its color.
Padauk Handles: Water, UV, and Color
Padauk wood handles need more restraint around water and light. To stop padauk color fading, do not put the knife in the dishwasher and limit its contact with water. For padauk wood handles, also limit exposure to UV because light can affect the wood's condition and make it go pale.
Avoid leaving a knife in the sun because the color could fade over time. Storing it in a drawer protects it from UV.
Polymer Handles and Dishwasher Use
Polymer handles are designed to cope well with water and can go in the dishwasher. That tolerance is a material property of the handle, not a universal rule for every utility knife, so confirm the handle material before choosing this route.
If the handle is wood or padauk rather than polymer, keep the knife out of the dishwasher and follow the hand-cleaning and drying steps instead.
Clearing the Blade Setting
Dust, dirt, and other muck can accumulate inside the blade setting, the area where the blade sits. Clean inside the blade setting with sandpaper folded in half or a compressed air blower.
This is a focused step rather than a full teardown. Treat it as part of routine care when debris is visible in that area.
A Catalog Example and Buyer Verification Questions
One example in the TOP KNIVES catalog is the EDC 13 in 1 Multifunctional Pocket Knife Stainless Steel Box Cutter with razor SK5 blade, wrench, bottle opener, and screwdriver. The product model is DGN-18, the material is stainless steel, the overall length is 9.5cm, and the product type is pocket multitool. Available tool type configurations are silver and black.
The care guidance above comes from manufacturer and first-party sources and is not a claim about this specific model. Before buying, consider asking the supplier which handle material the DGN-18 uses, whether the blade setting can be accessed for cleaning, and what cleaning method the supplier recommends for that configuration.
FAQ

Polymer handles are designed to cope well with water and can go in the dishwasher. Wood and padauk handles should not; limit their contact with water and keep them out of the dishwasher.
How do I clean inside the blade setting?
Dust, dirt, and other muck can accumulate inside the blade setting. Clean that area with sandpaper folded in half or a compressed air blower.
Should I oil a wood handle after cleaning?
Yes. After the handle is dry, apply nourishing oil with a dry cloth and leave it to dry for a few hours before using the knife again. Oiling can also revive its color.
