Tested Guide: How to Clean a Dehydrator Tray Fast

What You'll Need

I've tested dozens of cleaning methods on my own Excalibur and Cosori units over the last decade for cleaning a dehydrator tray, you don't need expensive chemical degreasers. In fact, harsh chemicals can ruin the plastic and leave toxic residues. Here is the exact kit I use in my kitchen, along with a few heavy-duty upgrades if your current trays are failing.

Step-by-Step Cleaning Guide

Cleaning a dehydrator tray isn't just about aesthetics. Leftover food particles harbor bacteria and mold spores that will ruin your next batch. Follow this exact sequence to get your trays factory-clean.

Step 1: Cool Down and Disassemble

Never wash a hot tray. Unplug the unit and let the trays cool to room temperature, which usually takes about 45 minutes. If you're making teriyaki beef jerky for a weekend camping trip, you'll notice the marinade drips and bakes onto the bottom tray while it's still hot. Removing a hot plastic tray can cause it to snap or warp permanently under its own weight. Stack them neatly on your counter.

Step 2: The Initial Dry Scrape

Grab a plastic bench scraper or an old credit card. Scrape off any large, visible chunks of dried fruit leather or jerky bits. Do this over a trash can. Skipping this step means you. clog your sink drain with rock-hard food particles. It takes about three minutes per tray, but it saves you a massive plumbing headache later.

Step 3: The Hot Vinegar Soak

Fill your sink or a large plastic tub with hot water. I aim for exactly 140°F, which is hot enough to melt fruit sugars but won't warp BPA-free plastic. Add two tablespoons of Dawn Ultra dish soap and one cup of white vinegar. The vinegar's acidity breaks down the sticky fructose bonds, while the Dawn tackles any residual oils. Submerge the trays completely. I'll be honest, soaking six trays in a standard kitchen sink is a logistical nightmare. You might need to do it in two batches or use a plastic storage tote. Let them soak for exactly 30 minutes. Don't leave them overnight, as prolonged water exposure can degrade the plastic mesh over time.

Step 4: Scrubbing the Mesh

Grab your OXO Good Grips soft-bristle brush. Scrub the mesh in a circular motion. It takes about five minutes to get the worst of the gunk off, but don't rush this part because dried fruit leather acts like cement once it cures into those tiny plastic crevices. Pay special attention to the corners where the frame meets the mesh. If you notice the plastic is cracking or flaking during this scrub, throw the tray away immediately and order the stainless steel replacements I linked above.

Step 5: Baking Soda for Jerky Grease

Water and vinegar won't cut through polymerized animal fat. If you dried meat, you'll see cloudy, greasy smears on the lower trays. Make a thick paste using three parts baking soda to one part warm water. Smear it directly onto the grease spots. Let it sit for 20 minutes. The alkaline baking soda saponifies the fat, turning it into a water-soluble soap. Scrub it again with your brush, and the grease will lift right off.

Step 6: Rinse and Sanitize

Rinse the trays under cold running water. Inspect them against a bright light to ensure no baking soda residue remains in the mesh holes. If you dried raw meat, I recommend a quick sanitizing spray. Mix one 2/3 cup of 3% hydrogen peroxide with water in a spray bottle. Mist the trays, let them sit for five minutes, and rinse with distilled water. Shake off the excess water.

Step 7: Dry and Wipe the Base Unit

Dry the trays thoroughly with your microfiber cloths. Air drying leaves water spots and takes hours. W while the trays are out, wipe down the inside of the dehydrator base unit with a damp vinegar0. Don't spray liquid directly into the fan or heating element. Scaling up a cottage food business? You'll eventually outgrow a countertop unit.
