TL;DR
A spiralizer must come apart to get clean. The cutting discs have dozens of small blades with pulp packed between them, and no amount of rinsing an assembled unit reaches them. Take out every disc, brush each one away from the cutting edges under hot running water, and dry the base and suction foot before storing.
Why a spiralizer is harder than it looks
A spiralizer cuts by pressing a vegetable against a spinning or fixed disc while a handle drives it forward. Each disc holds a straight blade plus a comb of small teeth, and every one of those teeth has a root where pulp collects.
Zucchini, sweet potato, and beet all release moisture and starch as they are cut, and that mixture dries into a film that binds shreds to the metal. Beet adds staining on top of it.
There is also a pulp core -- the leftover center of the vegetable -- and it usually ends up jammed against the disc or in the handle's gripping prongs. If that dries in place it takes a soak to remove.
The tool rinses in under a minute if you do it immediately. It becomes a fifteen-minute job if you do not. That timing rule is the backbone of our guide to cleaning kitchen tools without damaging them, and it matters more on a spiralizer than on almost anything else.
How do you clean a spiralizer?
Disassemble it completely, rinse each disc under hot running water within a couple of minutes of use, and brush the teeth with a small stiff brush moving away from the cutting edges. Wash the body and handle in hot soapy water, dry every part, and reassemble only when dry.
Brush away from the edges, never across them
Each tooth on a spiralizer disc is a small blade. Brushing toward the edge drives bristles and fingers into it; brushing away from it lets bristles lift debris out of the tooth root.
Hold the disc by its plastic rim or frame, never by the cutting face. Many discs have a molded ring specifically so there is a safe place to grip. Use it.
An old toothbrush is the correct size for the teeth, and a wooden skewer clears a single stubborn shred. Do not run a cloth or sponge over a disc face -- it catches, tears, and pulls your hand along the blades. The same rule governs how to clean a mandoline slicer, which is essentially one disc laid flat.
Take every part out, including the ones you forget
Countertop spiralizers usually break down into more pieces than people realize: the body, the crank handle, the pronged food holder, the blade cartridge or individual discs, the blade storage box, and the suction foot or clamp.
The pronged food holder is a frequent miss. Pulp packs between the prongs and dries into a solid plug. Brush between each prong under running water.
The blade storage box is another. Discs get put away wet, and the box collects water and grows spots. Wash and dry the box too.
Handheld spiralizers -- the cone type -- are simpler but have a hidden trap: the interior of the cone, where shreds collect out of sight. Rinse from the wide end so debris exits the way it entered.
The suction base and the mold problem
Most countertop spiralizers stick to the counter with a suction foot or lever base. That foot traps water underneath it, and it is stored in a cabinet.
Water plus vegetable residue plus a dark cabinet is the standard recipe for mold spots, and the underside of a suction base is where they turn up. Release the suction, wash the foot with hot soapy water and a brush, rinse it, and dry it with a towel.
Store the unit with the suction released, not stuck to a shelf. If there is a lever mechanism, work it a few times under hot water to flush the joint, then dry it.
If a base already has dark spots that will not wash off with soap and a brush, that is a part-replacement conversation rather than a cleaning one -- porous or cracked plastic cannot be reliably cleaned.
Dishwasher rules and drying
Many spiralizer parts are labeled dishwasher safe on the top rack, and that is a reasonable option for the body, handle, and food holder. Two cautions apply to the discs.
First, detergent and heat dull small blades faster than hand washing does. Second, and more important, loose blade discs in a dishwasher are a hand hazard for whoever unloads. If you put discs in, secure them in a closed rack compartment or a utensil basket, and tell whoever empties the machine.
Dry everything before it goes back together. Assembling a spiralizer wet traps water against the discs, which causes rust spots on the metal and mold spots in the plastic seams.
Air dry the discs on a rack blade-down for fifteen minutes rather than towel drying them. The same drying logic applies to any assembly with a gear housing, including how to clean a salad spinner.

FAQ
How do you clean spiralizer blades?
Remove each disc, hold it by its plastic rim, and brush the teeth under hot running water with a small stiff brush moving away from the cutting edges. Clear individual shreds with a wooden skewer. Never wipe a disc face with a cloth or sponge held in your hand.
Can a spiralizer go in the dishwasher?
Many parts are dishwasher safe on the top rack, including bodies, handles, and food holders. Discs can go in, but heat and detergent dull small blades faster, and loose discs are a hazard when unloading. Secure them in a closed compartment and warn whoever empties the machine.
How do you get dried pulp out of a spiralizer?
Soak the affected parts in hot soapy water for ten to fifteen minutes to soften the starch film, then brush the teeth away from the edges and work between the prongs of the food holder. Rinsing within a couple of minutes of use avoids the soak entirely.
How do you stop a spiralizer suction base from getting moldy?
Release the suction, wash the foot with hot soapy water and a brush, and dry it with a towel before storing. Trapped water under a suction foot in a dark cabinet is where spots start. Store the unit with the suction released rather than stuck to a shelf.
How should spiralizer discs be stored?
Fully dry, in the blade storage box the unit came with, or in a closed container that keeps edges covered. Wash and dry the storage box too, since discs put away wet leave water in it. Never leave loose discs in a drawer where a hand can reach in blind.
