The Problem With Most “Natural” Dish Soaps
Walk into any health food store and you’ll find dozens of dish soaps marketed as “natural,” “plant-based” or “eco-friendly.” But many still contain sodium lauryl sulfate (SLS), synthetic fragrance, and preservatives that accumulate in waterways. We checked the ingredient labels so you don’t have to.
Our Testing Method
We tested each product on: greasy cast iron, baked-on pasta residue, oily salad bowls, egg plates, and delicate wine glasses. We assessed: cleaning power, rinse-off ease, skin feel after extended use, scent, and ingredients.
Top 5 Non-Toxic Dish Soaps
🥇 #1 Branch Basics Dish Soap — Score: 9.2/10
Best overall. Completely transparent ingredients, EWG-verified, and genuinely effective on heavy grease. The concentrate dilutes 1:10, making it exceptional value. Fragrance-free version available — essential for chemically sensitive households.
🥈 #2 Blueland Dish Soap — Score: 8.9/10
Best zero-waste option. Refillable glass bottle with dissolvable tablet refills. Cleans well on most dishes, slightly less powerful on very heavy grease. Beautiful packaging that looks good by the sink.
🥉 #3 Dr. Bronner’s Sal Suds — Score: 8.7/10
Best value. A small amount goes a very long way. Made with plant-derived surfactants and fir needle oil — no synthetic fragrance, no parabens, no SLS. Available everywhere, very affordable.
#4 Seventh Generation Free & Clear — Score: 8.3/10
The most accessible option — sold at Target, Walmart and most grocery stores. Good ingredients, decent performance. The “Free & Clear” version is better than their scented versions ingredient-wise.
#5 Grove Co. Dish Soap — Score: 8.1/10
Solid performance, attractive packaging, FSC-certified bottles. The walnut scrubber duo that comes with it is a useful bonus. Slightly more expensive than the others but a good choice if you shop at Grove already.
Ingredients to Avoid
