The short answer: Clean the jars and lids in hot soapy water or the dishwasher, rinse well, and sanitize with a mild bleach solution, boiling water, or a sterilizing tablet. Never submerge the base unit in water; wipe it with a damp cloth and mild detergent. Air-dry everything completely before reassembling and storing.
Yogurt makers are simple appliances, but they create the perfect environment for bacteria to thrive, both good and bad. If your equipment isn’t properly cleaned and sanitized, you risk introducing harmful bacteria into your yogurt, which can ruin a batch or even make you sick. Plus, milk residue and mineral deposits from hard water can build up over time, affecting the performance of your yogurt maker and shortening its lifespan.
Understanding the difference between cleaning and sanitizing is crucial. Cleaning removes visible dirt and residue, while sanitizing kills invisible bacteria. Both steps are essential for safe yogurt making. Regular cleaning after each use, and a deeper sanitizing session periodically, will keep your yogurt maker in top shape.
Most yogurt makers come with glass or BPA-free plastic jars and lids. These are the parts that come into direct contact with milk and culture, so they need the most attention. Check your manual, but generally these parts are dishwasher safe (top rack) or can be hand-washed with hot, soapy water. If you hand-wash, use a non-abrasive sponge to avoid scratching plastic surfaces, which can harbor bacteria.
After washing, rinse thoroughly to remove any soap residue, because soap can kill the yogurt cultures you want to grow. Then, allow them to air-dry completely on a clean dish rack. If you’re in a hurry, you can dry with a paper towel, but air-drying is best to avoid recontamination.
Some yogurt makers also have a removable inner lid or sealing rings. Remove these and wash them separately, being careful not to stretch or damage rubber seals. A bottle brush can help clean the inside of jars thoroughly.
Sanitizing is an extra step that kills any remaining germs. There are several safe methods you can use on the jars and lids:
Whichever method you choose, let the parts air-dry completely. Some people prefer to sanitize right before making a new batch, but if you’ve dried them well, you can store them clean and sanitize again before use if you’re worried.
The base unit contains the heating element and electrical components. It should never be immersed in water or placed in the dishwasher. Instead, unplug the unit and wipe the exterior with a damp cloth and a drop of mild dish soap. Be careful not to let water drip into any vents or openings. You can use a cotton swab dipped in rubbing alcohol to clean small crevices.
If you spill milk or liquid on the base, wipe it up immediately to prevent it from baking on. For dried-on residue, make a paste of baking soda and water, apply it gently with a soft cloth, then wipe clean. Avoid abrasive cleaners, scouring pads, and harsh chemicals that can damage the finish.
Allow the base to dry completely before storing or using again. Store the yogurt maker with the lid off or slightly ajar to let any moisture escape and prevent musty odors.
For best results, clean the jars and lids immediately after each batch of yogurt. This prevents milk residue from drying and hardening. You should sanitize them before each use, especially if you’ve stored them for a while. Many people find that washing in the dishwasher with a hot cycle is enough for regular cleaning, but a separate sanitizing step is recommended for extra safety.
The base unit should be wiped down whenever it gets dirty, and at least once a month to keep it looking new. Also, check the ventilation holes for dust buildup and clean them gently with a dry brush.
If you use your yogurt maker frequently, aim for a deep clean every few months. Disassemble all removable parts, clean and sanitize thoroughly, and inspect for any wear and tear. Replacing worn seals or damaged jars is important for hygiene and performance.
To keep your yogurt maker running well for years, follow these simple tips:
When choosing a yogurt maker, consider one with dishwasher-safe parts for easier cleaning. For a range of reliable options, check out our best yogurt makers guide to find a model that fits your needs.
Most glass jars and many plastic jars are dishwasher safe, but it’s best to check your manual. Place them on the top rack, away from the heating element, and use a gentle cycle without high heat if you have plastic. Avoid using the sanitizing cycle if you’re unsure about the material.
Yes, even with pasteurized milk, you should sanitize to prevent contamination from bacteria that may be on the equipment. Yogurt cultures need a clean environment to thrive and outcompete other bacteria.
Soak the jars in a solution of warm water and baking soda for 15-20 minutes, then scrub gently with a soft sponge. You can also use white vinegar, but rinse thoroughly afterward to avoid affecting future batches.
Remember, a clean yogurt maker is the first step to delicious, safe homemade yogurt. Take the time to care for it, and it will serve you well for years.
