Clean the pasta attachment when ready after use, while the dough is still soft

The fastest way to clean a KitchenAid pasta attachment is to disassemble it right after you finish extruding, before the dough dries and hardens inside the dies. Most of the dried pasta will fall out on its own once you separate the parts. Dried dough that sticks to the metal dies is much harder to remove than soft dough, so timing matters.

Start by unplugging the mixer and removing the pasta attachment from the mixer head. Most KitchenAid pasta attachments slide straight off the drive shaft — no tools needed. Set it on a clean, dry surface and let any loose pasta pieces fall into a bowl or onto a cutting board.

Key Takeaways

  • Clean the attachment while dough is still soft, before it hardens inside the dies — this takes five minutes instead of thirty.
  • The die (the metal piece with the pasta shape holes) unscrews from the barrel and should be rinsed under running water, never soaked.
  • Use a soft brush or old toothbrush to gently clear the holes in the die; never use a metal pick or toothpick, which can enlarge or damage them.
  • Dry all parts completely with a cloth before storing, because moisture left inside the barrel can cause rust.
  • The pusher rod and auger screw can go in the dishwasher, but the die and barrel should be hand-washed only.

Separate the die from the barrel

The die is the metal piece with the holes that shape your pasta — it screws onto the end of the barrel. Hold the barrel steady with one hand and turn the die counterclockwise with the other. It will unscrew after a few turns. If it is stuck, wrap a dry cloth around it for grip, but do not use pliers or a wrench, which can dent the metal.

Once the die is off, you will see the auger screw — the spiral metal rod inside the barrel. This screw pushes the dough through the die. Most of the soft dough will still be clinging to it. Tap the barrel gently over a trash can or bowl to dislodge the loose pieces.

Rinse the die under running water

Hold the die under warm running water and let the water flow through the holes from both sides. Use your fingers to gently rub away any dough stuck to the surface. The holes should clear quickly if you caught the attachment while the dough was still soft.

Never soak the die in water, because moisture can seep into the small spaces and cause rust over time. If dough has already hardened inside the holes, soak the die for only five to ten minutes in warm water, then rinse and brush gently. Do not use hot water, which can warp the metal.

Use a soft brush to clear stubborn dough from the holes

An old toothbrush or a soft brass brush works well for clearing the pasta holes without damaging them. Wet the brush and gently scrub the die from both sides, working the bristles into each hole. You should see dough particles come out. Rinse again under running water.

Never use a metal pick, toothpick, or wire brush to poke the holes clear. These tools can enlarge the holes or scratch the metal surface, which will change the shape of your pasta and can lead to rust. If dough is truly stuck and a soft brush does not work, soak for a few more minutes and try again.

Clean the barrel and auger screw

Rinse the inside of the barrel under warm running water, turning it so water flows through from both ends. Use your fingers or a soft cloth to wipe away any dough clinging to the auger screw. The screw has a spiral shape, so dough can hide in the grooves — run your finger along each groove under running water.

The auger screw and pusher rod can go in the dishwasher on the top rack if you prefer, but hand-washing takes only a minute and is gentler on the metal. The barrel itself should be hand-washed only, because the dishwasher spray can force water into the seams where the barrel connects to the drive shaft.

Dry everything completely before storing

Moisture left inside the barrel or on the die will cause rust, especially if the attachment sits in a cabinet for weeks between uses. Dry all parts with a clean cloth, paying special attention to the inside of the barrel and the grooves of the auger screw. You can stand the barrel upright on a cloth and let it air-dry for a few minutes if needed, but do not store it while damp.

Once everything is dry, screw the die back onto the barrel by turning it clockwise until it is snug — do not over-tighten. Store the attachment in a cool, dry place, ideally in the box it came in or in a sealed plastic bag to keep dust out.

What to do if dough has already hardened

If you did not clean the attachment right away and the dough has hardened inside the die, soak the die only (not the barrel) in warm water for ten to fifteen minutes. This softens the dough enough for a soft brush to clear it. After soaking, rinse under running water and brush gently from both sides of the die.

If dough has hardened inside the barrel, do not soak the whole barrel. Instead, fill the barrel with warm water, let it sit for five minutes, then empty it and rinse thoroughly. Use a soft cloth to wipe the inside. Repeat if needed. Dry completely before storing.

Frequently Asked Questions

Can I put the pasta attachment in the dishwasher?

The auger screw and pusher rod are dishwasher-safe on the top rack, but the die and barrel should be hand-washed only. Water forced into the seams of the barrel by the dishwasher spray can cause rust. Hand-washing takes just a few minutes and keeps the attachment in better condition.

What if I see rust spots on the die?

Light surface rust can be removed by soaking the die in warm water with a little white vinegar for ten minutes, then scrubbing gently with a soft brush and drying when ready. If rust is deep or pitting, the die may need to be replaced. Contact KitchenAid customer service with your mixer model number for a replacement part.

How do I know if the die holes are damaged?

If your pasta comes out misshapen, thinner on one side, or with rough edges, the die may be damaged. You can inspect it by holding it up to a light and looking through each hole — they should be smooth and uniform. If you see enlarged, rough, or irregular holes, the die needs replacement.

Should I oil the attachment before storing it?

No — oil can trap moisture and cause rust. Store the attachment dry in a cool place. If you live in a very humid climate, you can place a small packet of food-grade silica gel in the storage container to absorb moisture, but do not explore oil to the metal.
