How to Clean Baby Toys & Bottles Non-Toxically
Key Takeaways
- Conventional dish soaps and toy cleaners often contain synthetic fragrance, dyes, and surfactants like 1,4-dioxane (a likely carcinogen byproduct of certain foaming agents) that rinse incompletely from bottles and toys — hot water, steam, and plant-based cleaners are safer and equally effective.
- Phthalates and bisphenols (BPA, BPS, BPF) found in plastic toys and bottles are endocrine disruptors — meaning they can interfere with your baby's hormones — and have been associated with altered brain development and behavior; heat and mouthing accelerate leaching from plastic surfaces.
- Rubber bath toys with squirt holes harbor dense bacterial and fungal growth inside (including potential pathogens, per research published in npj Biofilms and Microbiomes) and are nearly impossible to fully clean — replacing them with open, solid toys is the single highest-impact bath toy swap you can make.
Why Your Baby's "Clean" Toys May Not Be as Safe as You Think
If you're already reading labels on your own shampoo and questioning your non-stick pans, it makes complete sense that you'd wonder what's actually on the toy your baby just put in their mouth. Again.
Here's the thing: babies and toddlers mouth toys constantly, and their skin is thinner and more permeable than adult skin, which means they absorb more of whatever is on the surface of those objects. Add warmth — from bath water, a sunny floor, or a hot car — and the chemicals in plastic toys and bottles leach faster and more readily into the environment your baby is touching and tasting.
This isn't about fear. It's about making one or two smarter swaps so you're not unintentionally adding to your baby's toxic burden during the most vulnerable window of their development. That's it. Let's walk through it.
What Chemicals Are Actually on Baby Toys and Bottles?
Phthalates and Bisphenols: The Two Big Ones
Phthalates are a group of chemicals used to make plastics soft and flexible — and they can be found in abundance in many plastic baby toys, especially those made with PVC (polyvinyl chloride). They are known endocrine disruptors, which means they can interfere with your baby's hormonal system. Research published on PubMed has associated phthalate exposure with disruptions to reproductive development and behavior in children.
Bisphenols — including BPA, BPS, and BPF — are industrial chemicals used to harden plastics. They are commonly found in baby bottles, food containers, and can linings. They can mimic estrogen in the body, potentially affecting hormonal balance, brain development, and behavior. The National Institute of Environmental Health Sciences (NIEHS) notes that BPA exposure is a particular concern during fetal and infant development. Don't be fooled by "BPA-free" labels alone — BPS and BPF replacements carry similar concerns.
SCRUNCHY MOM TIP: "BPA-free" doesn't mean chemical-free. When possible, choose bottles and toys made from food-grade silicone, natural rubber (without squirt holes), or solid wood rather than any hard or soft plastic.
Even plastic toys marketed as "clean" often contain stabilizers, dyes, and softeners that are not regulated for safety in items intended for mouthing. Warm bath water accelerates the leaching of these chemicals from plastic bath toys — making the bath, ironically, one of the higher-exposure moments of your baby's day.
What's Wrong with Conventional Baby Toy and Bottle Cleaners?
The Problem with "Baby-Safe" Dish Soaps
Many conventional dish soaps — even ones marketed toward families — contain synthetic fragrance, artificial dyes, and surfactants that are far from clean. One of the most common concerns is 1,4-dioxane — a likely human carcinogen that forms as a byproduct of certain foaming agents, and is not an intentional ingredient, which means it doesn't have to appear on labels. The Environmental Working Group (EWG) has flagged 1,4-dioxane contamination in children's personal care products — and the same surfactants appear in bottle washes.
Synthetic fragrance is a blanket term that can hide hundreds of undisclosed chemicals, including additional phthalates. The American Academy of Pediatrics (AAP) has specifically called for reducing children's exposure to chemicals found in food packaging and household products, including those that act as endocrine disruptors. When you're washing a baby bottle with a fragranced soap and rinsing it out, residue remains — and your baby drinks from it.
The fix doesn't require buying ten new products. It requires swapping one: your bottle and toy cleaner.
How to Clean Baby Toys Safely (by Toy Type)
Hard Plastic and Wooden Toys
For hard plastic and wooden toys, warm water with a plant-based, fragrance-free cleaner does the job well. Avoid soaking wooden toys, as prolonged moisture can crack the finish or cause mold.
Start here this week: Wash hard plastic toys with warm water and a small amount of properly diluted castile soap. Rinse thoroughly and air dry completely before returning to your child's reach.
Silicone and Teething Toys
Silicone teething toys are one of the safest toy categories for mouthing, but they still need regular cleaning. Most food-grade silicone toys are dishwasher-safe on the top rack, or can be washed with hot water and a plant-based soap. You can also boil them briefly to sanitize.
Bath Toys — The Hidden Mold Problem
This is where it gets real. Rubber bath toys with squeeze holes are nearly impossible to fully clean or dry. Squeeze them after a bath and you'll often see black mold shoot out into the water your baby is sitting in. Research published in the Nature partner journal npj Biofilms and Microbiomes found that squeeze bath toys harbor dense bacterial and fungal growth inside — including potential pathogens — with polymer-leached nutrients from the toy material itself feeding that microbial growth.
The scrunchy solution isn't to obsessively bleach them (bleach exposure is its own concern). It's to phase them out. Replace squeeze bath toys with open-sided silicone or natural rubber bath cups, stackers, or simple waterproof books that can drain and dry completely.
SCRUNCHY MOM TIP: Cut the hole of any current squeeze bath toys wider so they can actually drain and dry — or toss them and replace with toys that have no enclosed cavities at all. Your future self will thank you.
What Should You Actually Clean Baby Toys and Bottles With?
The Safest Cleaning Options
Look for cleaners that are plant-based, free from synthetic fragrance, optical brighteners, and dyes, and safe for household surfaces (rinse before food contact). Here are the options worth keeping in your kitchen:
- Scrunchy All-Purpose Wipes — quats-free, rinse surfaces thoroughly before food or skin contact, individually wrapped, and free from synthetic fragrance. These are genuinely useful for a quick wipe-down of toys on the go, at restaurants, or on airplane tray tables without reaching for a conventional disinfecting wipe loaded with harsh chemicals.
- Branch Basics Concentrate — diluted in warm water, it's an effective, non-toxic option for soaking bottles and washing toys. Their formula is fragrance-free, plant-based, and certified safe for use around kids and pets.
- Castile Soap (properly diluted) — a single-ingredient, plant-based soap that rinses completely. Dr. Bronner's Unscented is the version to reach for — avoid the peppermint or lavender options for baby items.
- Force of Nature — an electrolyzed water cleaner made from just salt, water, and vinegar. It's EPA-approved as a sanitizer and contains no synthetic chemicals, making it a strong option for sanitizing toys after illness.
How to Clean Baby Bottles Specifically
- By hand: Use warm water with a small amount of Branch Basics All-Purpose or diluted castile soap, and a dedicated bottle brush. Rinse thoroughly.
- To sanitize (for newborns, after illness, or after travel): Boil heat-safe bottles for 5 minutes, use a steam sterilizer, or run through a dishwasher with a steam-dry cycle. The CDC recommends sanitizing infant feeding items at least once daily for babies under 3 months, those born prematurely, or those with a weakened immune system.
- Avoid: Fragranced dish soaps, antibacterial soaps with triclosan, or anything with synthetic dye. These leave residue and add unnecessary chemical exposure.
Safer Bottle Options
If you're still using hard plastic bottles, this is a good moment to consider a swap. Comotomo bottles are made from soft, food-grade silicone — BPA-free, PVC-free, and designed with a wide neck that makes them significantly easier to clean thoroughly. Glass bottles are another excellent option for home use.
A Note on Air Quality While Cleaning
One thing that often goes unmentioned: conventional cleaners release VOCs (volatile organic compounds — airborne chemicals that off-gas into the air and can be inhaled) during and after use. The EPA notes that VOC concentrations indoors can be two to five times higher than outdoors, and cleaning product use is a primary contributor.
If you're cleaning in a nursery or small bathroom, open a window. And if your home air quality is a concern, a medical-grade HEPA air purifier can help reduce the buildup of VOCs and allergens. Austin Air makes robust HEPA units specifically rated for chemical and VOC filtration — a legitimate long-term investment for a nursery environment.
If you're on a tight budget, start with castile soap and hot water for bottles, and don't stress yet about an air purifier. The cleaner swap matters more immediately.

FAQ
Q: Is white vinegar safe to use on baby bottles and toys?
White vinegar is a non-toxic, effective way to reduce surface bacteria and mineral buildup on toys and bottle parts. It is not an EPA-registered disinfectant and will not eliminate all pathogens the way boiling water or steam will. For healthy babies over 2 months, a vinegar rinse (1 part white vinegar to 1 part water) followed by a thorough water rinse is a reasonable option for routine cleaning. For newborns or after illness, use steam or boiling water to sanitize. The CDC recommends daily sanitizing of feeding items for babies under 3 months or those with weakened immune systems.
Q: My baby's toys say BPA-free — isn't that enough?
Not entirely. "BPA-free" means one specific bisphenol was removed, but manufacturers often replace it with BPS or BPF — chemicals with similar endocrine-disrupting concerns. Research published in Environmental Health Perspectives found that many BPA-free plastics still leach estrogenic chemicals, particularly when heated or stressed. For mouthed toys, food-grade silicone, solid natural rubber, or untreated wood are safer long-term material choices than any plastic — BPA-free or otherwise.
Q: How often should I be cleaning and sanitizing baby toys?
For babies under 3 months, clean frequently mouthed toys daily with warm water and plant-based soap, and sanitize at least once daily per CDC guidance. For older infants and toddlers with developing immune systems, cleaning every few days and sanitizing after illness is generally sufficient. Bath toys should be rinsed and fully dried after every single use — if they cannot drain and dry completely (like sealed squeeze toys), replace them with open designs that can. The AAP emphasizes reducing unnecessary chemical exposures during infancy as a core prevention strategy, which means routine toy hygiene with non-toxic methods matters more than you might expect.
