Hello, fellow kitchen enthusiasts! This is TheKitchenApplianceDad.com, your go-to source for all things kitchen appliances. Today, we’re tackling a common issue that many Blendtec blender owners face: cloudy blender jars. If you’ve noticed that your once crystal-clear Blendtec jar has become foggy or opaque, you’re not alone. But fear not, because I have some easy and quick fixes to help restore your blender jar’s clarity.
Understanding Why Blender Jars Turn Cloudy
Before we dive into the solutions, let’s understand why this happens. Cloudiness in blender jars can be attributed to several factors:
- Mineral Build-Up: Hard water can leave mineral deposits on the jar after multiple uses and washes.
- Starch Residue: Blending starchy foods like potatoes or pasta can leave a film on the jar.
- Scratches: Over time, the jar may develop micro-scratches from blending hard ingredients, which can make it look cloudy.

Quick and Easy Fixes for Cloudy Jars
Now, let’s look at some effective methods to clear up that cloudiness and get your Blendtec jar looking like new.
Vinegar Soak
What You’ll Need:
Steps:
- Create a Vinegar Solution: Mix equal parts of white vinegar and warm water in your Blendtec jar.
- Soak: Let the jar soak for several hours, or even overnight, if the cloudiness is severe.
- Scrub: After soaking, use a non-abrasive sponge or brush to scrub the jar gently.
- Rinse and Dry: Rinse the jar thoroughly with water and dry it with a clean cloth.
Baking Soda Scrub
What You’ll Need:
Steps:
- Make a Paste: Combine baking soda with a little water to form a paste.
- Scrub: Apply the paste to the inside of the jar and scrub with a non-abrasive sponge or brush.
- Rinse and Dry: Rinse the jar well and dry it to prevent new water spots from forming.
Lemon Peel Rub
What You’ll Need:
Steps:
- Rub the Jar: Take some fresh lemon peels and rub the inside of the jar with them. The natural acidity helps break down mineral deposits.
- Rinse and Dry: Thoroughly rinse the jar and dry it with a clean towel.
Commercial Cleaners
What You’ll Need:
- Commercial descaler or cleaner (designed for kitchen use)
Steps:
- Follow Instructions: Use the cleaner according to the manufacturer’s instructions, typically involving a soak or scrub.
- Rinse and Dry: Make sure to rinse the jar completely to remove any cleaner residue and then dry it off.
Preventative Measures to Keep Your Blender Jar Clear
- Use Softened Water: If possible, use softened water to reduce mineral build-up.
- Immediate Cleaning: Clean your jar immediately after use to prevent residue from drying and sticking.
- Hand Wash: Although Blendtec jars are dishwasher safe, hand washing can be gentler and prevent etching from harsh detergents.
- Avoid Abrasive Scrubbers: Stick to soft sponges or brushes to avoid creating scratches that can lead to cloudiness.
Key Takeaways
- Cloudiness in Blendtec jars is commonly caused by mineral build-up, starch residue, and scratches.
- To clear up cloudiness, try a vinegar soak, a baking soda scrub, a lemon peel rub, or a commercial cleaner.
- To prevent future cloudiness, use softened water, clean immediately after use, hand wash when possible, and avoid abrasive scrubbers.
