Can You Use Dish Soap as Laundry Detergent?

We’ve all been there—laundry day rolls around, and the detergent’s nowhere to be found. It’s tempting to reach for that bottle of dish soap, but is that really a safe move? Spoiler: not quite. While both products clean, they’re designed for entirely different purposes. In this article, we’ll break down the key differences between dish soap and laundry detergent, what could go wrong if you swap them, and why Blueland makes it easy to clean sustainably, with the right formulas for every task.

Can You Use Dish Soap as Laundry Detergent?

While both are designed to clean, dish soap and laundry detergent are not interchangeable. Understanding the differences can help protect your clothes, your washing machine, and your skin.

Key Differences Between Dish Soap and Laundry Detergent

Dish soap is designed for scrubbing grease and food residue off hard surfaces like plates, pans, and glass. Laundry detergent, on the other hand, is formulated specifically for fabric. It contains enzymes that break down sweat, oils, and other fabric-based stains while rinsing clean in washing machines.

• Dish soap is thick and sudsy—great for scrubbing plates, but not ideal for machines.

• Laundry detergent is low-sudsing by design, which protects high-efficiency (HE) machines and ensures thorough rinsing.

• The pH balance of laundry detergent is fabric-safe, while dish soap may not be.

Why Dish Soap Is Not Formulated for Fabric or Washing Machines

Using dish soap in your washer can lead to more than just bubbles; it can produce excessive suds that overwhelm HE machines, leading to error codes or water damage.

Also, dish soap doesn’t rinse clean from fabric, leaving a residue that may cause irritation or make clothes feel stiff. Some dish soaps contain dyes and fragrances not tested for fabric use, increasing the risk of staining or skin issues.

What Happens If You Use Dish Soap in the Washing Machine?

Dish soap might seem like a quick fix when you run out of laundry detergent, but it can cause more harm than good. Using dish soap in your washing machine can lead to a bubbly mess—literally.

Risks Like Excessive Suds, Machine Damage, and Residue on Clothes

Dish soap creates too much foam for washing machines, especially high-efficiency models. The suds can overflow, delay cycles, or even cause your machine to shut down. Residue can also build up inside the washer, leading to unpleasant odors and long-term issues.

Clothing may come out stiff, sticky, or soapy-smelling, and leftover ingredients can irritate skin, especially for those sensitive to fragrances or dyes. Using a detergent designed for fabric is safer for your clothes, your washer, and your skin.

Safe and Effective Alternatives to Traditional Laundry Detergent

Why Laundry-Specific Products Are Better for Clothes and Machines

Laundry detergents are built for textiles. Their pH is gentler on fabric fibers, and many formulas include enzymes that target protein- and oil-based stains. Unlike dish soap, they’re made to rinse out completely, preventing buildup on clothing and inside the machine. This means fewer skin issues, better cleaning performance, and longer-lasting clothes.

5 Things to Look for in a Safe, Low-Waste Detergent

1. Biodegradable Ingredients: Opt for plant-based or naturally derived ingredients that break down safely in the environment.

2. Minimal Packaging: Prioritize detergents with low-waste or plastic-free packaging, like recyclable tins or compostable wrappers.

3. No Unnecessary Fillers: Avoid products with bulking agents or additives that do not contribute to cleaning performance.

4. Free from Artificial Dyes and Synthetic Fragrances: These can irritate skin and pose risks to marine life once they enter the water system.

5. Third-Party Certifications: Look for eco-labels like EPA Safer Choice or USDA BioPreferred as a sign of safer, more sustainable formulas.
