Tested: How to Get Grease Out of Dehydrator (2026)

Immediate Action (First 5 Minutes)

Unplug it. You don't want to risk a shock while wiping down the heating element with a damp cloth. Wait. Let the metal cool down to about 110°F before you touch anything. If you're making high-fat sausages or marbled beef jerky for a weekend camping trip, grease will splatter everywhere and bake onto the interior walls. I've found that tackling the drips while they are still slightly warm makes a huge difference.

Grab a dry paper towel. Wipe up any visible pools of fat from the bottom drip tray or the floor of the unit. Don't use water yet. Adding water to hot, liquid grease just spreads the mess around the interior fan and forces it into the electrical housing. Toss the greasy paper towels in an outside trash bin so your kitchen doesn't smell like old fryer oil. This initial five-minute triage saves me at least twenty minutes of heavy scrubbing later on.

What You'll Need

I'll be honest, scrubbing fine mesh screens is a massive pain. Having the right tools cuts my cleaning time from an hour down to about 20 minutes. Here is exactly what I keep under my sink for this job. I've tested dozens of products, but these specific items consistently deliver the best results without damaging the plastic.

Item	Brand / Model	Price Range	Purpose
Dish Soap	Dawn Platinum Powerwash	$4.50 - $6.00	Cuts through polymerized animal fats
Scrub Brush	OXO Good Grips Dish Brush	$7.99 - $9.50	Reaches into mesh without bending it
Powder Cleanser	Bar Keepers Friend (Liquid)	$3.50 - $5.00	Removes stubborn, baked-on resin spots
Detail Swabs	Q-Tips Precision Tips	$3.00 - $4.00	Cleans tight corners near the fan housing

Avoid the green side of standard Scotch-Brite sponges. They leave tiny micro-scratches in polycarbonate trays. Those scratches trap bacteria and grease during your next batch, making future cleanings much harder.

Step-by-Step Removal

Step 1: Complete Disassembly

Pull out every single tray. Remove the mesh inserts if your model allows it. I use an Excalibur 9-tray, and the screens pop out with a little flex. Stack them in your sink. Don't force the plastic. If a screen feels stuck, run warm water over the edges for ten seconds to soften any hardened fat acting like glue.

Step 2: The Hot Soak

Fill your sink with water as hot as your tap allows. Ideally, you want the water around 130°F to 140°F. Squirt in a generous amount of Dawn Platinum. Submerge the trays and screens completely. Let them sit for exactly 20 minutes. This breaks down the polymerized fat that bakes onto the plastic during a 12-hour jerky cycle. You'll see the water turn cloudy as the grease lifts.

Step 3: Scrubbing the Mesh

This is where most people ruin their screens. Don't use steel wool. I use the OXO Good Grips brush and scrub in circular motions. Apply light pressure. If you push too hard, the fiberglass or polyethylene mesh will warp and never sit flat again. Focus on the corners where fat tends to pool. Rinse the brush frequently in clean water so you aren't just smearing grease back onto the clean spots.

Step 4: Tackling the Main Unit

Never submerge the main housing. Unplug it again just to be safe. Dampen a microfiber cloth with warm soapy water and wring it out until it's barely moist. Wipe the interior walls carefully. Use a dry cotton swab to dig grease out of the tight corners near the fan housing. If you have a Cosori model with a digital display, use a separate dry cloth to wipe the screen so you don't streak it with oily residue.

Step 5: Rinse and Dry

Rinse all trays with warm water. Dry them immediately with a clean towel. Air drying leaves hard water spots that look exactly like grease stains. I like to let them sit on a dry towel on the counter for an extra ten minutes just to ensure no moisture is trapped in the mesh weave before storing them.

Alternative Methods

Sometimes the standard soap soak just doesn't cut it. If you left your dehydrator sitting in the garage for a month after making salmon jerky, the grease turns into a hard, sticky resin. Here are three backup methods I've tested when the Dawn soak fails.

Baking Soda and Vinegar Paste

Mix three parts baking soda with one part white vinegar. It fizzes up aggressively. Smear this thick paste directly onto the stubborn grease spots on the drip tray. Let it sit for 15 minutes. Scrub it away with a soft sponge. This isn't the cheapest option, but it works wonders on hardened fat that soap simply slides right off of.

Enzyme Cleaners

I keep a bottle of Puracy Natural Multi-Surface Cleaner ($12.99) for tough organic stains. Enzymes literally eat the fat molecules at a microscopic level. Spray it on the trays and let it sit for 10 minutes before wiping. It smells like green tea and leaves zero chemical residue behind, which is critical when you are prepping surfaces for food.

The Dishwasher Trick (With Warnings)

Some manuals say the trays are dishwasher safe. I've put my Excalibur polycarbonate trays in the top rack on a delicate cycle. They survived. However, the high heat of the drying cycle warped my cheaper mesh screens permanently. Only risk this if your trays are explicitly marked top-rack safe by the manufacturer. Always skip the heated dry setting and let them air dry on the counter instead.

Prevention Tips

Cleaning is fine, but avoiding the mess entirely is much better. When your landlord inspects next week, you don't want a greasy, smelly appliance sitting on the counter looking like a science experiment. Implement these habits to keep your machine pristine.

• Use Silicone Mats: I bought a pack of 9-inch silicone dehydrator sheets for $15.99 on Amazon. They catch all the dripping fat. You just peel the mat off and wash it in the sink in seconds.
• Trim Visible Fat: Before slicing your meat, freeze it for 45 minutes. This makes it firm. You can easily slice off the hard white fat caps with a sharp chef's knife. Less fat means less grease splatter inside the chamber.
• Parchment Paper Punching: In a pinch, poke holes in regular parchment paper with a wooden skewer. Lay it on the trays. It catches drips but still allows adequate airflow for drying.
• Rotate Trays Early: Halfway through the drying process, swap the top and bottom trays. This ensures even drying and prevents the bottom trays from sitting in a puddle of dripping grease for hours on end.
• Blot Marinades: If you marinate your jerky in oil-heavy sauces, pat the meat dry with a paper towel before placing it on the mesh. The flavor is already in the meat, and you'll save yourself a massive cleanup job.

FAQ

Can I use oven cleaner on my dehydrator trays?

Absolutely not. Oven cleaners contain lye and other harsh caustic chemicals that will melt the plastic trays and leave toxic residue. You are drying food on these surfaces, so you must stick to food-safe degreasers like dish soap or baking soda.

Why does my dehydrator smell like old grease even after cleaning?

The smell usually comes from grease that splattered directly onto the heating element or fan blades inside the main unit. You can't take the main unit apart easily, so try running the empty dehydrator at 160°F for 30 minutes with a small bowl of white vinegar placed on the bottom tray to neutralize the odors.

How often should I deep clean the machine?

I do a quick wipe-down after every single use, especially when making fruit leathers or meats. However, I completely disassemble and soak the trays once a month if I am dehydrating high-fat items like beef jerky or sausages multiple times a week.

Is it safe to use a magic eraser on the plastic trays?

I don't recommend it. Magic Erasers are essentially micro-sandpaper that will scratch the smooth surface of your polycarbonate trays. Those tiny scratches will trap grease and bacteria during your next batch, making future cleanings much harder.

How should I store the dehydrator to prevent grease from going rancid?

Always ensure the trays and the interior are 100% dry before putting the machine away in a cabinet. I leave the door cracked open with a folded towel for a few hours after cleaning to let any hidden moisture escape, which prevents mold and rancid oil smells from developing in storage.
