TL;DR
Two rules cover most baby gear cleaning. First, the manufacturer's manual governs, especially for anything that restrains a child -- car seat harness webbing must never be submerged, machine washed, bleached or solvent-cleaned, because those treatments weaken the fibers invisibly. Second, everything a child mouths needs a full rinse, since detergent residue matters more here than anywhere else in the house.
Why Kids Gear Has Its Own Rulebook
Most household items only need to end up clean. Children's gear also needs to end up safe, and the two goals sometimes pull in opposite directions.
A stronger cleaner removes more soil, but leaves residue that a toddler puts in their mouth. Hot water sanitizes better, but warps a plastic sippy valve. Bleach whitens fabric, but degrades the load-bearing webbing in a restraint. The right answer is usually the gentler process, repeated, rather than the stronger one.
The other complication is that gear is assembled. Straps thread through frames, pads snap over bars, and trays lock into rails. Soil collects in exactly those joints, so cleaning almost always means partial disassembly and photographing the setup before you take it apart.
What Is the Rule for Cleaning a Car Seat?
Follow the car seat manual, and nothing else. Covers usually detach and are washable on the manual's stated settings. The harness webbing is different -- it must never be submerged, machine washed, bleached or solvent-cleaned, because those treatments can weaken the fibers without any visible sign. Manufacturers typically allow only wiping with mild soap and water.
This is the single highest-stakes item in the cluster, which is why it gets an explicit warning rather than a technique. If the manual is lost, the manufacturer publishes them by model number.

The same caution applies to bike helmets, booster seats and any harness on a stroller or high chair. Structural safety gear is cleaned the way its maker says, or not at all.
Wash Tags, Rinse Rules and Residue
For everything textile, the care label is the instruction set. Most infant fabrics are cotton or polyester blends that take a warm gentle cycle, but flame-resistant sleepwear and waterproof mattress covers have specific limits, and fabric softener degrades both.
The rinse step deserves its own attention. Detergent left in fabric can irritate skin, and detergent left on a feeding item ends up swallowed. When in doubt, run an extra rinse. This is one place where using less product and rinsing more is genuinely better practice, not just caution.
Odor that survives washing is usually milk protein, which sets permanently in hot water. Protein soils need cold water first and an enzyme detergent, a rule the odor removal guide covers across the house.
Bath Toys, Mold and the Squirt Problem
The black material that comes out of a squeezy bath toy is mold, growing in a sealed, permanently damp interior that no cleaning method can dry out.
There is no reliable way to clean the inside of a closed squirt toy. The practical options are to seal the hole so water never enters, choose solid or openable toys instead, or replace the toy. Bleach soaks do not solve it, because the mold regrows in the same conditions within days and the toy still cannot be dried.
Open bath toys, on the other hand, wash easily and can air dry in a mesh bag outside the tub.

Sanitizing Feeding Items Without Overdoing It
Washing removes the soil. Sanitizing is a separate step that reduces germs on an already-clean item, and current public health guidance treats it as most important for newborns, premature infants and infants with weakened immune systems rather than as a daily requirement for every healthy older baby.

Where sanitizing is used, boiling, steam or a dishwasher sanitize cycle are all recognized methods. What matters afterward is drying items on a clean, dedicated rack in open air rather than towel-drying them.
Questions about a child's health, allergies or skin reactions belong with a pediatrician, not a cleaning routine.
Products to Keep Away From Kids Gear
Strong disinfectants, chlorine bleach and solvent cleaners have almost no place on children's equipment, and the risk is not only the chemical itself but the residue. Fragrance-heavy products create a second problem, because they mask odor rather than removing its source.
Never mix products while cleaning gear, and ventilate the space. The full set of rules on that is in the cleaning safety guide, and material-specific damage is covered in the cleaning mistakes hub.
FAQ
Can you machine wash a car seat harness?
No. Harness webbing must never be machine washed, submerged, bleached or cleaned with solvents, because those treatments can weaken the fibers with no visible change. Manufacturers generally allow only wiping with mild soap and water. Always follow the specific manual for your seat model.
How do you get mold out of a squirting bath toy?
You generally cannot. A sealed squirt toy stays wet inside, which is exactly what mold needs, so it regrows after any soak. The practical answers are to seal the hole, switch to solid or openable toys, or replace the toy outright.
Do baby bottles need to be sterilized every day?
Washing thoroughly after every use is the essential step. Health guidance treats daily sanitizing as most important for newborns, premature infants and babies with weakened immune systems. For older, healthy infants, careful washing and full air drying on a clean rack is generally considered sufficient.
What is the safest way to wash stuffed animals?
Check the tag first. Most plush toys tolerate a cold gentle cycle inside a mesh bag or pillowcase, with a low-heat or air-dry finish. Toys with electronics, glued eyes or delicate trim should be surface cleaned by hand and left to air dry completely.
Is bleach safe to use on children's toys?
It is rarely necessary and easy to get wrong. If a diluted bleach solution is used on a hard, non-porous toy for a specific reason, it must be followed by a thorough water rinse and full air drying. Never use bleach on fabric restraints, porous toys or anything a child mouths regularly.
How often should baby gear be cleaned?
Feeding items after every use, bibs and cloths daily, high chair trays and straps weekly, and strollers, carriers and play equipment monthly or after any spill. Anything that has been in storage should be cleaned before it comes back into use.
Kids gear multiplies fast, and it tends to be the category that gets cleaned reactively rather than on a schedule. When the rest of the house needs to keep up, our house cleaning services handle the surfaces while you keep the gear on your own terms. Every home is different, so the real number depends on size, condition, and what you want covered -- get a quote and we will walk you through it.
