Why Cleaning a Teething Toy Set Deserves More Attention Than It Usually Gets
A silicone teether lands on the floor, gets picked up, goes straight back into your baby’s mouth — and most parents either wipe it on their shirt or run it under the tap. Both approaches leave a lot on the surface that shouldn’t be there.
Silicone teethers accumulate saliva, milk residue, dust particles, and microbial contaminants faster than most caregivers expect. The material itself has a genuine advantage here: silicone’s non-porous surface resists bacteria and stains better than other materials like wood or fabric. But that non-porous quality doesn’t make silicone self-cleaning. An oily film from saliva can still coat the surface and hold onto microorganisms even when the teether looks clean.
For very young babies — generally under six months — the stakes are a bit higher. Their immune systems are still developing, which is why teethers that are well-loved and used daily should ideally be washed after every use, especially if you have a young baby whose immune system hasn’t fully developed yet. Once babies are past six months, a daily wash with mild soap tends to be enough for routine maintenance, with a deeper sterilization reserved for post-illness or post-drop-on-public-floor situations.
Knowing which method to use — and when — saves time and protects the teether from wear that comes from over-processing.
The Four Methods That Actually Work
Everyday hand-washing is the baseline and the method you’ll use most. Wash your hands first, then clean the teether with warm water and a gentle, baby-safe dish soap. For teethers with grooves or textured surfaces, gently scrub with a soft baby bottle brush or toothbrush to clear residue from the ridges. Rinse until the water runs clear — any soap film left behind can irritate sensitive gums — and air dry on a clean surface before returning the teether to your baby.
Dishwasher cleaning is the method most Canadian parents with a busy household will reach for first, and for good reason. Silicone teethers can be easily washed with soap and water and are often dishwasher safe, making them convenient for busy parents. Always place teethers on the top rack only — away from the heating element at the bottom — and use a mild detergent. The heat and steam in the dishwasher provide a strong cleaning without much effort. Allow the teether to cool and air dry completely before handing it back.
Boiling is the most effective sterilization method for solid food-grade silicone teethers, and it’s straightforward to do. Bring a pot of clean water to a rolling boil, turn off the heat, and submerge the teether for 3 to 5 minutes. Remove with tongs — never with bare hands — and place on a clean towel to air dry completely before use. Avoid boiling for longer than 5–8 minutes, as extended exposure to high heat can affect the elasticity of the silicone over time. This method works well after a baby has been sick, or after a teether has been dropped somewhere particularly unsanitary.
Steam sterilization is a practical option if you already own a baby bottle sterilizer. Electric steam sterilizers are quick, efficient, and hassle-free — just add water and let the steam do its thing. Follow the sterilizer manufacturer’s guidelines for cycle length. UV sterilizers are also safe and effective for 100% food-grade silicone teethers, killing bacteria using ultraviolet light without heat or moisture — a good choice for parents who prefer a chemical-free, waterless method.
One method worth skipping: the microwave. Most silicone teether sets should not go in the microwave, and several manufacturers explicitly state this on their product care labels. Check your specific product before trying any heat method you haven’t used before.
What to Avoid (and Why It Matters for Silicone Specifically)
The material properties that make silicone so good for teethers — flexibility, softness, non-porosity — are also what make it sensitive to the wrong cleaning agents. Never use bleach, antibacterial wipes, or harsh cleaning agents on silicone teethers. These chemicals can degrade the silicone material or leave harmful residues that may irritate your baby’s gums.
Alcohol-based cleaners fall into the same category. They may seem thorough, but they can break down the silicone surface with repeated use and leave traces that don’t belong near a baby’s mouth. Stick to baby-safe dish soap, white vinegar diluted in water, or baking soda solutions if you want a natural deep-clean option that won’t compromise the material.
For the vinegar method, mix equal parts white vinegar and water, soak the teether for 10–15 minutes, then rinse thoroughly and air dry. Vinegar’s natural acidity handles germs while keeping things baby-safe — though the smell does linger briefly, so a good rinse matters.
For baking soda, mix water and baking soda into a paste or solution and soak for five to ten minutes before rinsing. This is a useful method if you’re unsure whether a toy is safe to boil or use with a steam sterilizer, or if you want to address any discolouration on the silicone surface.
Also worth noting: teething sets that include a strap holder or pacifier clip — rather than a standalone teether — need a slightly different approach. For teething toys with string or attached clips, it’s important not to sterilize by boiling or steaming. Hand-wash the entire set with warm soapy water and rinse thoroughly instead. This protects the integrity of the strap while still clearing bacteria effectively.
How Often to Clean, and When to Replace
A practical cleaning schedule for most households: hand-wash or dishwasher-clean daily, and sterilize by boiling or steam roughly once a week, or immediately after illness or a significant drop. If the teether falls on the floor or gets sticky, clean it immediately. After each use, at minimum, rinse the teether under warm running water to remove saliva and food particles.
But cleaning only matters as long as the teether is still structurally sound. Inspect teethers regularly to ensure they are still suitable for your child — if the teether is broken or has any signs of weakness and damage, replace it. Silicone is durable, but repeated chewing eventually creates micro-tears or surface breakdown that can harbour bacteria even after cleaning. A teether that’s starting to look pitted, cloudy, or misshapen has probably reached the end of its useful life.
And on the question of passing teethers down to a second child: if you have a second child about to enter the teething phase, it’s generally not recommended to reuse a previous teether as it can become contaminated after being stored away for some time. A fresh teether is a small investment relative to the hygiene risk.
For Canadian parents shopping for a set that makes this whole routine easier, Loulou Lollipop’s silicone teether sets are designed with cleaning in mind from the start. The teethers are top-rack dishwasher safe and can also be sterilized in a favourite sterilizer, or hand-washed with mild baby soap and rinsed with water. The food-grade silicone — free of BPA, PVC, phthalates, lead, and cadmium — holds up to repeated cleaning cycles without degrading, which matters when you’re running a teether through the dishwasher every other day for months. The Daisy Silicone Teether Set, for example, includes a one-piece molded strap holder made from the same food-grade silicone as the teether itself, so the entire set can be cleaned using the same method without worrying about mixed materials.
Getting the cleaning routine right takes about two minutes per day. The bigger challenge is simply building the habit — but once it’s automatic, it’s one less thing to think about during what is already a busy phase.
