Keeping your popcorn machine clean is crucial for making delicious popcorn that is safe to eat. A dirty machine can harbor bacteria, mold, and residue that can contaminate popcorn and even make customers sick. Additionally, a buildup of hardened kernels, oil residue, and grease can prevent your machine from working properly.
This step-by-step guide will teach you how to thoroughly clean your popcorn machine so it continues churning out fresh, hot popcorn for years to come. We’ve included tips on cleaning the kettle, exterior, and other components, as well as sanitizing to kill germs. With some time and elbow grease, you’ll have sparkling clean popcorn in no time.
The Dangers of a Dirty Machine
A dirty popcorn machine poses major health risks:
- Bacteria growth – Leftover grease, oil, and food debris provide the perfect breeding ground for dangerous bacteria like E. coli and salmonella. This bacteria can contaminate the popcorn and oil and cause serious foodborne illness.
- Mold – Any trapped moisture in the kettle or base of the machine can cause mold to grow. Inhaling this mold while eating popcorn could trigger respiratory issues or allergic reactions.
- Rancid oil – Old oil can turn rancid from repeated heating/cooling and contact with food debris. Rancid oil emits nasty odors and can cause stomach upset.
- Vermin infestation – Food residue and grease will inevitably attract pests like cockroaches or mice if not cleaned up. These vermin spread disease and contaminate food.
The Benefits of a Clean Machine
Regular cleaning provides huge benefits:
- Fresh, appetizing popcorn every time
- Machine lasts longer before repairs needed
- Safer popcorn with no risk of contamination
- More efficient popping performance
- Lower long-term maintenance costs
So while cleaning the popcorn maker is a chore, it pays off in the long run through healthier snacks and operational efficiency.

Step 1: Unplug and Fully Cool
Before cleaning anything, you must unplug the popcorn maker and let it completely cool.
Why unplug? The heating elements, kettle agitator, lights, etc. may turn on unexpectedly while cleaning and cause electric shock or burns.
Why let it cool? The metal and parts become dangerously hot during operation – up to 230°F for kettle surfaces. Attempting to wipe or handle hot components can severely burn skin.
So make sure your popcorn machine is unplugged from power and that the kettle and all parts are at room temperature before starting. This cooling off period takes at least 90 minutes after popping.
Now it’s safe to clean!
Step 2: Remove and Empty Kettle
The removable kettle chamber holds the oil and kernels during popping. It requires special attention because oil, salt, and scorched corn buildup accumulate internally over time.
Here is how to remove and empty the kettle:
- Locate the kettle locking clamp or latch beneath the chamber. This metal brace hooks over a ridge along the outer kettle wall to hold it in place.
- Open the latch using the attached handle so it disengages from the kettle ridge.
- Carefully lift the kettle directly upward to slide it off the central mixer rod and heating element. The kettle may feel quite heavy when full of oil so brace yourself.
- Pour hot popcorn oil into an appropriate container through the kettle pour spout for reuse or safe disposal later.
- Use a plastic spatula to scrape out any loose popcorn kernels, salt crystals, or debris stuck to the inner kettle. Discard waste.
- Set aside the empty kettle in a safe spot for dedicated cleaning.
Now the popcorn gunk needs to be scrubbed out!
Step 3: Clean Kettle
Tackling kettle cleaning first makes the overall process much easier since it’s the dirtiest component. Here is an effective multi-step kettle cleaning procedure:
- Pre-soak – Fill kettle about 1/3rd full with hot water and dish soap. Allow to soak for 15-20 minutes so grease and grime softens.
- Agitate – Use a stiff nylon brush with long handle to vigorously scrub the entire inner surface while kettle soaked. This loosens stuck-on scorched kernels and oily buildup.
- Rinse – Thoroughly rinse away all soap with hot clean water. Be sure to remove any bristles that detach from brush during scrubbing.
- Sanitize – Mix sanitizing solution of 2 tablespoons bleach per gallon water. Swish this solution around and soak for 5 minutes.
- Second Rinse – Flush out sanitizing solution completely using hot clean water. Repeat as needed to eliminate bleach smell.
- Dry – Allow kettle to fully air dry upside down to prevent moisture accumulation.
For really stubborn buildup, try soaking the kettle in white vinegar overnight before scrubbing instead of detergent. The acetic acid in vinegar breaks down tough mineral deposits and burnt corn pieces.
Stay committed until the metal walls appear shiny and free of oily residue before moving to other components. Any missed spots will lead to faster re-soiling during future popping cycles.
Step 4: Clean Exterior Surfaces
While the kettle usually gets dirtiest, oil droplets, dust, and debris also collects on the outer housing and surfaces over time.
Follow this process to refresh the rest of your popcorn maker:
- Wipe down the outer kettle walls, lid, and any detachable components with all-purpose cleaner solution and paper towels.
- Use a small vacuum crevice tool to gently suck up loose particles from narrow spaces on the machine frame.
- Dampen soft cloth with cleaner solution to wipe down flat exterior surfaces of the base, warming deck, trim pieces, etc. Avoid using excessive moisture.
- Carefully lift the warming deck light to dislodge any debris around the bulb region since this is a hot spot for grime accumulation.
- Scrub stubborn oil splatters on the base or case metal using a soft brush and cleaner spray.
- Shine and buff all cleaned areas thoroughly with a dry microfiber cloth once wiping is finished.
When working on electrical components like control panels:
- Never spray cleaner directly onto buttons or wiring
- Dampen cloth instead and wring thoroughly
- Avoid abrasive scrub brushes to prevent scuffing
This top-to-bottom wiping removes greasy residue so outer metal sparkles! Now just the hidden crevices and circuits left…
Step 5: Degrease and Sanitize Interior
The popping action blasts oil throughout the machine body with kernels hitting all surfaces. Over time, drips collect anywhere oil can seep like gaps around heating rods, the agitator shaft, kettle power connections, etc. Opening up the machine and degreasing these zones prevents heavy buildup behind the scenes.
Follow this process for internally degreasing a popcorn maker:
- Disassemble – Use the socket wrench to fully detach side and rear panels granting internal access. Keep all hardware together.
- Cover electronics – Drape a plastic bag over any exposed wire terminals or electrical components to keep them moisture-free.
- Remove grease – Use plastic spatulas and paper towels to scrape out thick oil residue accumulating on rods, heating elements, motors, brackets, etc.
- Clean with solvent – Apply all-purpose cleaner to a cloth and wipe down frame and non-electrical areas to further cut remaining grease. Avoid wires or circuits.
- Sanitize surfaces – Mist internal metal areas with sanitizing solution and let sit 10 minutes before wiping. This kills any germs from dripped butter or oil.
- Dry thoroughly – Carefully dry all interior metal and other zones with a clean rag to remove excess moisture. Leave doors off overnight.
When cleaning internally:
- Never spray liquids directly in open electrical areas
- Completely dry parts before reconnecting power
These best practices prevent short circuits or other electrical hazards while revitalizing hidden sections prone to heavy gunk accumulation from popped corn.
Step 6: Dry and Reassemble
With all cleaning stages now finished, it’s crucial to fully dry and reassemble everything properly before making popcorn again. Any trapped moisture causes part corrosion over time or dangerous electric shorts.
Follow this cautious reassembly process:
- Ensure all kettle and interior parts are 100% dry before re-installing. Wipe with clean cloth if any doubt.
- Reconnect removable kettle carefully onto mixer shaft and heating element receptors.
- Re-latch the kettle clamp securely to restore sturdy chamber wall attachment. Verify kettle is locked by trying to lift upwards – there should be no wiggle room when properly fastened.
- Inspect heating rods, agitator, and other connections for oil drips or debris that could spark and ignite during popping. Use compressed air if needed to dislodge particles.
- Replace all housing panels and fasten securely with original hardware to seal internal components safely.
- Reconnect machine to power but do not add oil. Turn on for 5 minutes ensuring heating and agitator operates smoothly without odd sounds.
- Power down again once operation verified. Only add fresh popcorn oil once completely convinced machine is clean, reassembled correctly, and functions normally.
You must follow safety measures when handling electrical equipment to avoid potential fire hazards or burns. Never rush the drying and reassembly steps.
