A food dehydrator is simple to clean—there is no heating oil or baked-on grease—but sticky fruit sugars, marinade and small food bits love to hide in the tray mesh and around the fan. Cleaning it properly after each batch keeps flavors from mixing, prevents odors, and is a genuine food-safety step when you dry meat. Here is the full routine.
What You’ll Need
- Warm water, mild dish soap and a soft sponge or cloth
- A soft brush or old toothbrush for the mesh
- White vinegar or a baking-soda paste for sticky residue and odors
- A microfiber cloth for the base and fan housing
How to Clean a Food Dehydrator, Step by Step
1. Unplug and cool. Let the unit and trays return to room temperature before handling.
2. Remove all trays, mesh screens and sheets. Take out every tray, any fine-mesh inserts and the fruit-leather sheets so nothing traps residue underneath.
3. Soak the trays and inserts. Submerge them in warm, soapy water for 10–15 minutes. Soaking loosens dried fruit sugar and marinade so you are not scrubbing hard.
4. Wash gently. Use a soft sponge or brush to clear the mesh openings. Avoid steel wool and scouring powder, which scratch plastic trays and can damage nonstick mesh. A soft toothbrush is ideal for stuck bits in the grid.
5. Wipe the base, lid and fan area. Clean the housing, lid and the area around the fan and heating element with a barely damp cloth. Never submerge the base or let water into the motor; just wipe away dust and splatter so airflow stays clear.
6. Dry everything completely. Air-dry or towel-dry all parts before reassembling. Storing a damp dehydrator invites mold and odors.
Dealing With Sticky Residue and Odors
Fruit leathers and honey-based marinades leave the stickiest mess. If soaking does not fully lift it, make a paste of baking soda and water, apply it to the spot, wait a few minutes, then wipe. For strong smells—garlic, onion or fish jerky—wipe the trays with a half-and-half white vinegar and water solution, then rinse. Running an empty machine for a short while afterward helps air out any residual odor.
Can You Put Dehydrator Trays in the Dishwasher?
Some trays are top-rack dishwasher-safe, but only if the manual says so—high heat can warp thin plastic trays over time. When in doubt, hand-wash. Fine-mesh screens and fruit sheets almost always last longer with gentle hand-washing. If your trays are warped or cracked, many brands sell replacements; if the machine itself is past its prime, see our picks for the best small food dehydrator.
Hygiene Matters Most With Meat
Drying jerky raises the stakes. Raw-meat juices can leave bacteria on trays, so wash every surface that touched the meat in hot, soapy water before and after, and follow current USDA jerky guidance for safe preparation. Clean, dry trays also keep your next sweet batch from tasting like last week’s teriyaki. If you are weighing a dehydrator against using your oven, see food dehydrator vs oven.
How Often Should You Clean It?
Wash the trays, mesh and sheets after every batch. Wipe the base and fan area whenever you see dust or splatter, and do a vinegar or baking-soda deep-clean any time residue or odor builds up. Because dried food stores for a long time, a vacuum sealer keeps it fresh afterward—see the best compact vacuum sealer for a small kitchen.
Frequently Asked Questions
Can you wash dehydrator trays in the dishwasher?
Only if the manufacturer lists them as dishwasher-safe, and usually on the top rack. Hand-washing is gentler and extends the life of trays and mesh screens.
How do you clean sticky fruit residue off the trays?
Soak in warm, soapy water, then lift stubborn spots with a baking-soda paste. Avoid abrasive pads that scratch the trays.
How do I get smells out of a dehydrator?
Wipe the trays and base with a white-vinegar-and-water solution, rinse, dry fully, and run the empty machine briefly to air it out.
Do you have to clean a dehydrator after every use?
Yes—clean the trays and sheets after each batch to prevent flavor transfer and odors, and always after drying meat for food safety.
