Why won’t my blender lid come off?

Having trouble removing the lid from your blender can be incredibly frustrating. You need to use your blender to make a smoothie or mix up a sauce, but the lid is completely stuck in place no matter how hard you try to twist or pry it off. Don’t worry, this is a common issue that most blender owners will run into at some point. There are several possible reasons why your blender lid may be stuck and refuse to budge. Read on to learn why your blender lid is stuck and how to get it off easily.

Common Reasons a Blender Lid Can Get Stuck

Here are some of the most common reasons that blender lids can become stubbornly stuck in place:

Vacuum Seal

The blending process can create a strong vacuum inside the blender jar that essentially suction cups the lid in place. Blenders are designed to be air-tight to prevent leaks and spills. But this air-tight seal also makes it difficult to break the lid free after blending. Vacuum pressure builds up during blending as ingredients spin rapidly, removing air from the jar.

Liquid or Food Buildup

Small particles of food or sticky blended ingredients like dressings, nut butters, or smoothies can cling to the rim of the blender jar or underside of the lid. As these bits of food or liquid dry, they act like glue bonding the lid to the jar.


It’s easy to twist the blender lid on too tightly out of habit. Overtightening the lid makes it more challenging to loosen and remove later on. You may have even tightened it without realizing.


Repeated use in the dishwasher or handwashing can cause warping of the plastic lid over time. A warped, misshapen lid will no longer fit cleanly onto the blending jar for easy removal.

Cracked Lid

Cracks or fractures in the lid, even hairline ones, affect the seal and suction. This can make the lid adhere stubbornly to the blender jar. Cracks develop from normal wear and tear over years of use.

Swollen Rubber Gasket

Many blender lids have a rubber gasket that creates the seal between the lid and jar. This gasket can become swollen after regular use, especially if often exposed to heat during washing. A swollen gasket makes the lid fit too tightly.

Damaged Blender Jar Rim

If the jar’s rim is warped, cracked, or has rough edges, this prevents the lid from sitting flush. An uneven rim alters the fit between lid and jar, which can lead to sticking.

Tips for Removing a Stuck Blender Lid

Don’t force the lid or resort to prying it open with knives or other utensils which can damage it. Try these simple tips first to safely remove a stuck blender lid:

Tap Lid Edges

Use the palm of your hand to gently tap around the lid’s outer edges. This helps break the seal for more straightforward removal.

Run Lid Under Hot Water

Heat from hot tap water helps loosen and melt any dried-on goop of food acting as “glue” between the lid and jar.

Insert a Utensil

Slide a thin spatula between the lid and jar to gently ease the vacuum seal. Work it around the lid perimeter.

Place a Dish Towel

Put a folded dish towel over the lid to enhance your grip and provide extra leverage as you twist the lid.

Turn Upside Down

Invert the sealed blender so the lid is aimed at the floor. Gravity helps pull the lid downward, releasing suction.

Fill with Water

Pour a few cups of water into the sealed blender jar before trying again to unscrew the lid. The water weight applies outwards pressure.

Wiggle Lid While Twisting

As you twist the lid, rock it back and forth gently to break the stubborn seal. Don’t twist too hard.

Preventing a Stuck Blender Lid

You can stop blender lid sticking issues before they start with a few best practices:

Avoid Overfilling

Leave at least 1-2 inches of empty space at the top of the blender jar before blending. Overfilling results in food particles leaking onto the rim and lid.

Wipe Jar After Each Use

Immediately wipe off any drips, spills, or leftover bits on the jar rim and lid. Don’t let food dry and cake on.

Loosen Lid ASAP After Blending

Open the lid promptly after turning off the blender. Don’t let vacuum pressure build up.

Inspect Lid and Jar for Damage

Regularly check that neither lid nor jar is warped, cracked, or otherwise damaged. Replace damaged parts.

Hand Wash Gently

Clean the lid and jar by hand with mild soap and warm water. Avoid abrasive scrubbing.

Replace Gasket if Worn

Inspect lid gasket and purchase replacements if swollen, cracked, or loose.

When to Replace a Blender Lid

If your blender lid becomes frequently or permanently stuck, it may be time for a replacement. Look for these signs your blender lid needs replacing:

  • Visible cracks or fractures in the lid
  • Extreme warping that prevents proper fit
  • Gasket is ripped, missing sections, or keeps falling out
  • Bluetooth connectivity issues (for smart lid models)
  • Loose-fitting lid no longer seals jar properly

Most blender manufacturers sell replacement lids online or in stores at an affordable price. Purchase the exact replacement lid made specifically for your blender model.


A tightly stuck blender lid can be immensely aggravating when you’re trying to whip up a meal or drink. But in most cases, the seal can be broken with some gentle finesse using the tips above. Prevent issues in the future by taking care of your blender jar and lid properly after each use. When your lid gets too worn out for quick fixes, invest in a replacement lid to restore ease of use. With the right techniques and equipment care, you can keep blending to your heart’s content without the hassle of a stubbornly stuck lid.
