The Dishwasher Method

If you do not own or prefer the dishwashing machine, You can skip to the following method. This requires you to unscrew and separate the blender parts into various components and then place them in the device.

The main components include the lid, jar base, blades, and blender jar. The sealing ring should go to the bottom utensil basket of your machine. The other component can get the regular wash cycle. Once you are done, you can dry out the parts and store them safely till your next use.

While dishwashing has its advantage, it may not be the best or fastest. Read on!

The self-cleaning method

This is by far the fastest method in use. If you frequently use the Oster blender, you should stick to this and use the last method occasionally. Let’s get into it:

Tools needed: baking soda(optional), a squeeze of dishwashing liquid, warm water, cloth, and a bristle brush.

Step 1: Add 2-3 cups of warm water, a few drops of the washing liquid, and baking soda (if you blend jalapeno, garlic, or similar ingredient).

Step 2: Place the jar on the machine. Plug the blender and switch on the device.

Step 3: let it run for 15-30 seconds, pour out the content and rinse under running water.

Step 4: Towel dry and store it safely for next use.

The Manual Cleaning Method

We guess they say great things take a while, right? The Manual method is the perfect example. It appears to be the most time-consuming method, but it’s the best you can use to give that blender the royalty treatment it deserves.

The manual cleaning can be scheduled once a week or once a month, depending on your use frequency. For that first time, let’s get to know how to clean an Oster blender:

Step 1: Switch off the blender and unplug the motor base.

Step 2: Take out the jar and dismantle it. In dismantling, remove the jar lid and, most importantly, the Jar Base. Doing this is essential as the blender’s intersection with the base is usually dirty after long-term use. The Jar lid also contains a filler which should also be taken off.

Step 3: Plug your kitchen sink stopper to prevent the water from escaping. Add a zinc-filled volume of water and drops of liquid soap till it’s foamy enough.

Step 4: Put all components in the soap mix and wash them gently with a clean cloth. You might need a smaller cleaning brush for the filler and the blades if you have seeds in your blends. The locking seal ring[2] should be specially cleaned as it often develops moulds. You can use a brush, sponge and every safe means necessary for its cleansing.

Step 5: Strain the jar and remove residue water with a dry towel

Step 6: Couple the parts. Be careful with the blade. Store in a cool, dry place so it is in shape for your next use.

PS: If the stain is tough, you might need vinegar and a brush to wash the Jar base.

While blender cleaning seems rudimentary, the manual cleaning method is worth learning.

Step 1: Once you are left with the jar and jar base, you might be required to use a tongue and grove plier to unscrew it if it is difficult to do so with the hand.

Step 2: Clean the blade using small brushes with soapy water to get to its nooks and crannies.

Step 3: Towel dry and couple back to the base.

Step 4: Store away safely.
