5 'Harmless' Household Cleaners That Are Secretly Toxic to Your Pets
From sparkling kitchen counters and shiny bathroom floors to shampooed carpet, having a freshly cleaned home is the absolute best feeling. However, did you know that there are certain cleaning products that may actually be unsafe for your pets? Well, if you didn't, you do now, and knowing what types of cleaning products to avoid in a pet-friendly house is important for keeping all of your fur babies safe, healthy and happy in the home.
To find out more about the common household cleaners that are toxic to pets, we spoke with Dr. Stephanie Liff, a New York City-based veterinarian and practice owner who manages eight veterinarians across the Pure Paws Veterinary Care clinics. She also serves as a vet advisor for the dog nutrition and wellness company Spot & Tango.
Dr. Liff shares why some household cleaning products are more harmful to our pets than others (plus which ones to avoid at all costs), and the pet-friendly swaps you can make to your clean routine without sacrificing cleanliness. Read on to see how you can still have a nice and clean home without the potential risks to your fur babies. It's possible-if you know the smart swaps to do it.
Why 'Sparkling' Can Sometimes Mean 'Toxic'
We may want our homes to be sparkling clean, but sometimes that term may mean that the cleaners you use may be toxic to your pets. This is because of the way our pets experience chemical cleaners differently than we do, especially in regard to their sensitivity to scent.
"The nose of dogs and cats differs significantly from humans, so dogs have [a] 10,000 times better sense of smell than humans, and cats have [a] 14 times better sense of smell than humans, so they are scientifically more sensitive," Dr. Liff says. "Also, depending on the size of your pet, you may not safely be able to open windows and doors to air out a space after cleaning, so the scents may also be more concentrated, which is another difference."
Noses to the Floor: How Pets Experience Chemical Cleaners Differently
In addition to being more sensitive to scent, pets may experience cleaners differently thanks to their build and stature.
"In regards to floor cleaners and other cleansers used on devices or surfaces that are low to the ground, pets' noses are also low to the ground, so the exposure is more direct," Dr. Liff says.
Why Lingering Residue Is a Lethal Threat
Residue from cleaners can have a number of potentially dangerous effects, including injury to your pet or an impact on their organs.
"If the residue from cleaners lingers, it can make floors slippery, which can lead to injury," Dr. Liff says. "Also, since pets walk without shoes on the floor and then often groom their feet, they could be ingesting chemicals as well, which could impact their organs-specifically liver and kidneys-but also the skin is an organ that can be impacted by contact injury."
Toxic Household Cleaners for Pets
According to Dr. Liff, the top cleaners to keep away from your pets include products with toxic ingredients such as:
- Bleach
- Phenol disinfectants
- Ammonia
- Formaldehyde
- Quats (quaternary ammonium)
"While some levels of exposure may be safe, these chemicals have the potential to be harmful, so please be mindful of their use in homes with pets," Dr. Liff warns.

Recognizing the Subtle Signs of Chemical Toxicity
Knowing what to look for when it comes to chemical toxicity is essential knowledge for any pet parent.
Signs of chemical toxicity in pets may include:
- Salivating
- Drooling
- Lip smacking
- Sneezing or coughing (if the air is heavily perfumed with the cleaner)
- Red, irritated skin or eyes
- Eyes that tear up
"If you notice more severe signs like wobbliness, lethargy, changes in appetite or changes in gum color, this is a medical emergency and requires veterinary attention," Dr. Liff says.
When to Skip Google and Call Animal Poison Control Immediately
"I typically restrict poison control calls for known ingestions or exposures, but if your pet is acting sick and you think there is a possible ingestion or exposure, you should either go see your vet or an ER/urgent care vet, or contact your vet to discuss," Dr. Liff recommends.
Pet-Safe Swaps: How to Deep Clean Without the Danger
Before you empty out your whole cleaning caddy, know that it's possible to keep your home clean without harsh pet-toxic cleaners.
"Steam and diluted white vinegar are probably the best options for cleaning," Dr. Liff says. "Also, hypochlorous acid is a very safe option that has excellent antiseptic properties. Baking soda is safe and can be used on surfaces as long as you vacuum it away. Plant-based soaps diluted into warm water can be used as alternatives."
Now that you know this important information, you can keep your home clean without any dangerous consequences for your pet.
