How do you properly clean a blender without destroying it?

Clean a blender by filling the jar with warm water and a drop of soap, running the machine briefly, then rinsing. Wash the lid and any removable blade assembly by hand or in the dishwasher only if the maker lists those parts as dishwasher safe, and never put the motor base in water.

The five blenders compared in Best Blenders for Big Batches and Thick Smoothies show how much of the cleaning job the maker expects you to do by hand. Some publish a self-clean cycle with a stated run time, some list dishwasher-safe parts, and some say nothing about either. What follows is what each maker states, plus the general steps that keep a motor base dry and a jar free of scratches.

Start with the self-clean cycle if the maker publishes one

The Reslee Stainless Steel Blender states that it self-cleans in 30 seconds: add warm water and a drop of soap, run it for 30 seconds, and the maker says no disassembly is needed. That is the shortest published cycle among the five picks. The jar is a 72oz double-wall 304 stainless steel container, and the maker states the outer wall stays cool to the touch, which matters when you pour out warm soapy water right after a cycle.

The Aeitto Blenders for Kitchen publishes a similar routine. Its one-touch self-cleaning mode takes 30 seconds with water and detergent, and the maker states that all detachable parts except the motor base are dishwasher safe. The 68oz jar is the part you rinse; the base stays on the counter and gets a wipe, not a soak. Two makers publishing the same 30 second figure makes the routine easy to remember.

The MAGETANG 1800W Blender takes a slightly different approach. It publishes a quick self-cleaning function with a drop of soap and water, and it lists the pitcher, lids, tamper and to-go cup as top-rack dishwasher safe. The maker does not publish a run time for the self-clean function, so follow the general rule: run it long enough to loosen residue, then rinse. The 70 oz pitcher and the 20 oz to-go cup are the two vessels you will be rinsing most often.

Check which parts the maker lists as dishwasher safe

Dishwasher safe is a claim each maker either publishes or does not. The Hamilton Beach Power Elite publishes the clearest list of the five: the 40 ounce glass jar, the lid and the removable blades are all dishwasher safe. Glass and stainless steel take heat well, and a removable blade assembly can be lifted out and washed separately from the motor base.

The Ninja SS151 TWISTi Blender DUO does not publish a dishwasher claim in its feature list. Its published parts are the 1600 Peak-Watt motor base, a 24 Oz. single serve cup with lid, a 34 Oz. power pitcher, an 18 Oz. nutrient extraction single serve cup with lid, and a hybrid-edge blades assembly. Because the maker publishes no dishwasher statement for these parts, wash them by hand in warm soapy water and let them air dry.

The Reslee maker also publishes no dishwasher claim for its stainless jar or lid, so hand washing is the safe reading of that listing. Where a maker does publish dishwasher safe parts, keep the motor base out of the machine entirely. No maker on this list says the base is washable, and the base holds the motor and the controls.

Handle the blade assembly with care

Blades are the part most likely to be damaged by careless cleaning, and the makers describe them in different ways. The MAGETANG listing names 6-point stainless steel blades. The Ninja listing names a hybrid-edge blades assembly and a built-in Twist Tamper that pushes ingredients toward the blades. The Hamilton Beach listing names stainless steel Ice Sabre blades that are removable. A removable assembly can be washed on its own; a fixed one gets rinsed in place.

Never reach into a jar with a bare hand to scrub around a blade. Add warm water and soap, run the machine, and pour the water out. If residue stays stuck, let the soapy water sit for a few minutes before running the cycle again. The Reslee maker includes a tamper tool for thick recipes, and that tool is the right object to move food around, not your fingers.

Dry the blade area before you store the jar. The Aeitto maker publishes a 68oz BPA-free jar, and the MAGETANG maker publishes a 70 oz BPA-free pitcher. Both are large vessels with a wide opening, so a towel reaches the walls easily. Leave the lid off until the inside is dry so no moisture sits against the blade hub.

Keep the motor base dry and stable

The base is the part you cannot wash. Wipe it with a damp cloth and dry it immediately. The Reslee maker publishes a reinforced base with non-slip feet and an integrated dampening pad, and the maker states the unit stays put at high speed. A wet counter under those feet is a slipping risk, so dry the counter before you set the base back down.

Watch the cord and the controls. The Aeitto maker publishes an LED display panel that shows speed, time and program status. Liquid that runs down the front of a panel can reach the buttons, so wring the cloth out before you wipe near the controls. The Ninja maker publishes 5 preset Auto-iQ programs, and those buttons sit on the base as well. A dry wipe is enough for both.

Give the base room. The Reslee maker states the jar stands 16.5 inches tall, the MAGETANG unit is 19.7 inches tall, the Aeitto unit is 16.53 inches tall, the Ninja unit is 13.8 inches tall and the Hamilton Beach unit is 14.69 inches tall. If a unit sits tight under a cabinet, pull it forward before you lift the jar off, so you are not tipping a full jar of soapy water against the shelf above.

Build a short routine that protects the jar

Rinse immediately after pouring. A jar that sits with residue is harder to clean later, and the self-clean cycles the makers publish work best on fresh residue. The Reslee maker states the stainless jar resists stains and odors, and the MAGETANG and Aeitto makers both publish BPA-free plastic pitchers. Plastic can hold onto smells, so rinse those pitchers before the residue dries.

Use warm water, not boiling water, and a drop of soap rather than a full squeeze. Hot water in a cold glass jar is a stress the glass does not need, and the Hamilton Beach jar is glass. The maker publishes a 40 ounce glass jar with a spout, and the spout is a narrow channel that traps residue, so run water through it as well as around the jar.

Store the jar open. A lid screwed down on a damp jar traps moisture against the blade hub and the seal. The Ninja maker publishes several lids, including a spout lid for the nutrient extraction cup, and those small lids dry fastest when left off the cup. Set every part on a rack, let it air dry fully, then assemble. That single habit does more for a blender than any cleaning product.
