You read food labels at the grocery store. You pay attention to what goes in your body. But when is the last time you looked at what is living under your kitchen sink? This is your step-by-step guide to auditing what you have understanding the ingredient red flags, and making sustainable swaps that actually last.
Step 1: Pull Everything Out
Start with a full inventory. Take everything out from under the sink and put it on the counter. This matters because most of us have no idea what is hiding in there until we see it ALL at once.
Sort into three groups:
- Keep: Products you use regularly and feel confident about
- Research: Products you are not sure about
- Replace: Products that probably need to go
Do not throw everything away at once. Work through your "Research" pile using the guidance below, then replace items as you run out or as you find better alternatives. A gradual swap is more sustainable than buying ten new things in a single afternoon.
Step 2: Learn What to Look for on Labels
Cleaning product labels are notoriously vague. Unlike food, manufacturers are not required to disclose every ingredient on the package. Here are the terms worth knowing before you put anything back under that sink.
Fragrance (or Parfum)
This single word can represent hundreds of undisclosed chemical compounds. Synthetic fragrances are one of the most common sources of indoor air pollution and are linked to respiratory irritation, hormone disruption, and skin reactions.
Quaternary Ammonium Compounds (Quats)
Found in many disinfectant sprays and surface wipes, quats are associated with respiratory issues and skin irritation with repeated exposure. They are also harmful to aquatic ecosystems when washed down the drain.
Phthalates
Often hiding inside the word "fragrance," phthalates are plasticizing chemicals used to make scents last longer. They are classified as endocrine disruptors and are particularly concerning for children and pregnant women.
SLS and SLES
Common surfactants in dish soaps and cleaners. They can irritate skin and eyes, and the manufacturing process for SLES can introduce a byproduct called 1,4-dioxane, which is a probable human carcinogen according to the EPA.
Chlorine Bleach
Effective at disinfecting, but highly reactive. When accidentally mixed with ammonia or acidic cleaners, bleach produces toxic gases. It is also corrosive to skin, eyes, and airways with repeated use.

Step 3: Rethink Your Tools, Not Just Your Products
The cleaning products in your cabinet matter, but so do the tools you use to apply them. Most conventional kitchen cleaning tools are made from plastic and synthetic materials that shed microplastics directly into your water and eventually into waterways and oceans.
Your Kitchen Sponge
Conventional dish sponges are made from polyurethane foam, a petroleum-based plastic. They harbor bacteria, fall apart within weeks, and do not biodegrade in landfills. Every time you use one, it sheds microplastic particles onto your dishes and into your sink water. A plant-based sponge made from cellulose or loofah are naturally biodegradable, absorb well, and do not shed plastic. They clean just as effectively and are compostable at the end of their life.
Your Scrub Brush
Plastic dish brushes warp, melt near heat, and shed synthetic fibers. A sisal brush with a wooden handle is made from agave plant fibers, naturally durable, and fully plastic-free. It handles pots, pans, and produce scrubbing without any of the plastic baggage.
Your Dish Soap
Most dish soaps arrive in plastic bottles that are difficult to recycle due to food residue contamination. A liquid castile soap made from plant-derived ingredients is one of the most versatile swaps you can make. It works as a dish soap, a surface cleaner, and a general household cleaner, all from one bottle with a clean, short ingredient list. Or try a solid dishwashing soap bar and skip the bottle entirely!
Step 4: Build a Simpler Cabinet
One of the biggest realizations from a kitchen detox is how few products you actually need. Most households have five or six different cleaners when two or three cover everything. Here is a simple framework:
- A liquid castile soap for countertops and surfaces: a true multi-tasker made from plant-derived ingredients that works as a dish soap, surface cleaner, and general household cleaner all in one bottle
- A plant-based scrubber like a sisal brush or cellulose sponge for dishes and produce
- Baking soda and white vinegar as backup for tougher jobs (just do not mix them together as they cancel each other out and you lose the cleaning power of both)
That is genuinely enough for most kitchens. The fewer products under the sink, the easier it is to know exactly what is in your home.
Step 5: Dispose of What You Are Replacing Responsibly
Do not pour cleaning products down the drain. Most municipalities consider concentrated cleaning chemicals household hazardous waste. Check your local waste management website for hazardous waste drop-off events in your area. Many cities host these several times a year at no cost.
And here is an easy pro tip for the products you simply do not want anymore: post them for free on Facebook Marketplace or your local Buy Nothing group and offer porch pickup. We guarantee they will be in someone else's hands instead of a landfill in no time!
Empty plastic cleaning bottles should be rinsed and checked against your local recycling guidelines before going in the bin. Not all plastic cleaning bottles are accepted curbside depending on resin type and your location.
You Do Not Have to Do It All at Once
A full under-sink detox does not have to happen in a single afternoon. Start with the "Research" pile. Check the EWG database. Swap out your sponge this week when you need a new one. Replace the dish soap next time you run out. Each small swap adds up faster than you think, and before you know it, you'll have not only safer, cleaner products in your home, but less PLASTIC too.
The goal is not a spotless, zero-waste cabinet by tomorrow. The goal is knowing what is in your home and making intentional choices. That is already more than most people ever do.
