This Wirecutter Expert Cleans (Almost) Everything with Dish Soap
TL;DR
Wirecutter cleaning expert Andrea Barnes explains why dish soap is the most versatile and economical cleaner for nearly any household surface, outperforming specialized products while reducing environmental impact through multi-purpose use.
🧪 The Science of Dish Soap 3 insights
Surfactants break down oil and water
Dish soap molecules contain dual-affinity structures that bind oil to water, allowing effective removal of grease and body oils from surfaces.
Suds are purely psychological
Bubbles serve only as visual confirmation that soap is present and do not contribute to actual cleaning power despite consumer expectations.
Enzymes are excluded for safety
Unlike laundry detergents, dish soaps intentionally omit enzymes to ensure the formula remains safe for prolonged bare-hand contact.
🧽 Surprising Applications & Technique 3 insights
Universal degreaser for household surfaces
Effective on stainless steel appliances, kitchen cabinets, wood floors, yoga mats, bathroom fixtures, and as a pre-treatment for laundry stains.
Strict soaking time limits prevent damage
Fill a basin with tepid water and soap to soak items for 20 minutes maximum, never exceeding 2 hours to avoid ruining finishes or materials.
Dawn outperforms for laundry stains
Testing showed that original Dawn removes clothing stains significantly better than dedicated stain removers or naturally marketed dish soaps.
♻️ Testing Results & Environmental Impact 3 insights
Wide performance gaps between brands
Laboratory testing revealed substantial variance in grease-cutting ability, with weaker formulas requiring significantly more product to achieve equivalent results.
Top product recommendations
Palm Olive Clear offers the best value with simple, hypoallergenic ingredients, while original Dawn excels at heavy-duty degreasing tasks.
Green marketing often misleads consumers
Buying fewer multi-purpose products creates less environmental impact than purchasing multiple specialized cleaners with greenwashed labels.
Bottom Line
Replace specialized cleaners with a high-performance dish soap like Palm Olive Clear or Dawn, use proper soaking techniques to avoid damage, and prioritize buying fewer products over green marketing claims.
