How to Clean Cheese Off a Rotary Grater (2026): Step-by-Step

Cheese left on a rotary grater can harden into a waxy film that clogs the drum, dulls the cutting holes, and makes the handle harder to turn. If you attack it with a sharp knife or scrub aggressively while the drum is still installed, you can cut your fingers, bend the grater, or push cheese deeper into the mechanism. Moisture trapped inside the housing can also create odors and, on some models, rust.

The safest approach is to remove loose cheese promptly, take apart every washable component according to the manufacturer’s instructions, soften stubborn residue with cool or lukewarm water, and dry each piece completely. The method below works for most hand-crank rotary cheese graters, including common manual models such as the Cambom Rotary Cheese Grater Hand Crank Cheese Shredder and the OXO Good Grips Rotary Cheese Grater. Both are manual tools, so there is no motor or wattage rating to worry about; the important variables are the drum, pusher, clamp, handle, and housing.

What You Need

Before buying a replacement, check the product’s care instructions. Manual rotary graters commonly sell for about $20 to $30; for reference, the listed OXO model is $19.95 and the Cambom model is $26.99. A lower price does not mean every component is dishwasher-safe, so use the manufacturer’s instructions rather than assuming that the drum or housing can tolerate high heat.

Step-by-Step

1. Stop using the grater and remove loose cheese (1 minute)

   Set the grater on a stable counter and stop turning the handle. Remove any remaining block of cheese from the loading chamber. Use your fingers only on the safe, non-cutting surfaces; never reach into the drum. Tap the grater gently over a bowl or scrape the outside with a spoon to collect loose shreds.

2. Disassemble the grater completely (2–4 minutes)

   Separate the handle, drum, pusher, clamp, lid, and housing as the design permits. Many rotary graters release the drum by pressing or sliding a latch, while others require the handle to be turned to a particular position. Do not force a part that resists. Take a quick photo before disassembly if you are unfamiliar with the locking arrangement.

   Keep the cutting drum by its solid ends, not by the sharp perforated surface. If the drum does not detach, clean around it carefully without putting fingers inside the housing.

3. Remove dry clumps before adding water (1–2 minutes)

   Use a wooden toothpick or the blunt end of a skewer to lift out cheese packed in the drum holes. Work from the outside of the drum toward the inside, keeping the tool away from your fingers. Do not use a knife, fork, metal pick, or other hard tool that can enlarge the holes or scratch a nonstick finish.

   If the cheese is still soft, a soft brush may remove it immediately. Avoid vigorous brushing at this stage; pushing wet cheese farther into the holes makes the next step harder.

4. Soak removable parts briefly (5–10 minutes)

   Fill a basin with cool or lukewarm water and add a small amount of dish soap. Place the removable plastic parts and the drum in the water only if the care instructions permit soaking. A short soak softens dried cheese without allowing water to sit unnecessarily inside seams or bearings.

   Do not use boiling water. High heat can soften plastic, loosen fitted components, dull finishes, or make greasy cheese smear across the surface. If the drum includes a metal axle or handle connection, keep those areas submerged only as long as needed.

5. Brush the drum and housing (2–4 minutes)

   Hold the drum by its ends and brush in the same direction as the cutting surface, rather than dragging your fingers across the holes. A soft dish brush or toothbrush can work cheese out of the perforations. Rotate the drum gradually so you clean the entire circumference.

   Wash the housing, pusher, clamp, and handle separately. Pay attention to the underside of the clamp, the slot where the drum sits, and the joint around the hand crank. Use a damp, soapy brush for areas that should not be submerged.

6. Rinse until the water runs clear (1–2 minutes)

   Rinse every washed part under running water, directing the stream through the drum holes from both sides. Continue until no slippery soap or visible cheese remains. Soap residue can affect the taste of the next batch of food, while cheese left behind may develop an odor.

   Keep small parts away from the drain. A sink strainer or bowl makes it easier to prevent a latch, washer, or axle cap from disappearing.

7. Sanitize only when appropriate (1 minute)

   For a grater used with soft cheese, cooked food, or multiple ingredients, you may use a food-safe sanitizing solution after washing, but only if the product’s materials and care instructions allow it. Follow the sanitizer’s label directions exactly, including dilution and contact time. Never combine sanitizer with dish soap, vinegar, or another cleaning chemical.

8. Dry every component completely (10–30 minutes)

   Shake water from the drum and pat all parts with a clean, lint-free towel. Stand the drum on its end or place it where air can circulate through the holes. Leave the grater disassembled until the axle, seams, and underside of the housing are fully dry.

   Do not store the grater while it is damp. Trapped water can encourage rust on unprotected metal and produce a musty smell. Once dry, reassemble it and turn the handle several times to confirm that the drum rotates freely.

Mistakes to Avoid

• Using a knife to pry out cheese: A blade can slip or damage the drum. Use a wooden toothpick and a soft brush instead.
• Putting your fingers near the drum holes: The cutting surface can be sharp even when the grater is not moving.
• Pouring boiling water over the grater: Heat may warp plastic and spread melted fat over a larger area.
• Soaking the entire assembled tool: Water can enter joints, latches, or non-washable mechanisms.
• Using steel wool or abrasive powder: Scratches collect food residue and may remove a protective finish.
• Forcing the drum or handle apart: If a component will not release, consult the manual instead of twisting until it cracks.
• Skipping the drying step: A clean but damp grater can still develop rust or unpleasant odors.
• Assuming dishwasher safety: A removable part may be dishwasher-safe while the housing or drum is not. Check the exact model instructions.

How Often

Wash the grater after every use, even if you grated only a small amount of cheese. Fresh residue is usually removed in a few minutes; dried residue takes longer and is more likely to collect in the holes. Give the drum and housing a closer inspection after every few uses, especially if you grate oily cheeses, chocolate, nuts, or vegetables.

For a frequently used grater, inspect the cutting surface weekly for stuck food, discoloration, and bent holes. Clean the handle joint and clamp whenever you notice resistance. The best time to rinse the tool is immediately after use, before the cheese has had time to harden.

When to Call a Pro or Replace

Most manual rotary graters are inexpensive enough that replacement is more practical than repair. Replace the tool if the drum is cracked, badly rusted, warped, or no longer locks securely into the housing. A drum with bent cutting holes can produce uneven shreds and may shed metal or coating into food.

Stop using the grater if the handle slips, the clamp will not hold, or a sharp edge has developed on the plastic housing. Do not try to reshape a damaged drum with pliers. For a higher-priced or specialized model, contact the manufacturer for a replacement drum or latch; a professional repair is generally worthwhile only when the part is available and the grater has a durable, serviceable design.

FAQ

Can I put a rotary cheese grater in the dishwasher?

Only if the manufacturer specifically labels the individual parts as dishwasher-safe. High heat and strong detergent can warp plastic, dull metal, or damage a finish. When in doubt, hand-wash the removable parts and wipe the housing with a soapy cloth.

How do I clean cheese that has hardened inside the drum?

First remove as much dry cheese as possible with a wooden toothpick. Then soak the removable drum in cool or lukewarm soapy water for 5 to 10 minutes and brush through the holes from both sides. Repeat once rather than using a sharp metal tool.

Can I use vinegar or baking soda?

Plain dish soap and water are usually sufficient. Vinegar can leave an odor and may affect some finishes, while baking soda can be mildly abrasive. If you use either product, confirm that the manufacturer permits it and rinse thoroughly.

Why is my grater still hard to turn after cleaning?

Check for cheese trapped around the axle, handle joint, or drum slot, then confirm that the drum is seated correctly. If the handle remains stiff after everything is clean and dry, the axle may be bent or the housing may be damaged. Do not add cooking oil unless the manufacturer recommends a food-safe lubricant for that specific part.
