Can I Use Dish Soap in the Washing Machine? Here’s What You Need to Know
When you run out of laundry detergent, it might be tempting to reach for the bottle of dish soap sitting beside your sink. Dish soap is great at cutting grease and cleaning plates, so surely it could work for your clothes, right? The truth is more complicated—and using dish soap in your washing machine can lead to tricky problems. Let’s break down whether it’s a safe substitute, why it’s usually discouraged, what could happen if you’ve already tried, and what to do if you’re in a pinch.
Why Dish Soap and Washing Machines Don’t Mix
At first glance, all soaps may seem similar—they lather, clean, and rinse away dirt. But there are important differences:
1. Dish Soap Creates Too Many Suds
- Dish soap is designed for manual dishwashing, where lots of suds are helpful for loosening grease and grime.
- Laundry detergents, on the other hand, are made to produce low foam, especially for high-efficiency (HE) washing machines.
- Excess suds from dish soap can overflow from your washing machine, making a heavy, sticky mess across your laundry room floor.
2. Risk of Machine Damage
- Too many suds can seep into mechanical parts of your washer, damaging pumps, seals, and electrical components.
- The soap can coat the inside of pipes and hoses, leading to costly blockages or repairs.
3. Incomplete Rinsing
- Dish soap is formulated to be rinsed by hand, not by the faster rinse cycles of a washing machine.
- Clothes washed with dish soap may feel sticky, soapy, or have an unpleasant residue.
4. Not Designed for Fabrics
- Dish soaps aren’t tested for use on fabric and may be too harsh, stripping fabrics of color or breaking down some fibers over time.
- Some dish soaps also contain dyes or fragrances that can cause irritation or leave discoloration.
What Happens If You Use Dish Soap in Your Washing Machine
If you’ve tried washing clothes with dish soap, you’ll quickly notice:
- Suds pouring out from the machine door or detergent drawer
- A soapy film left on clothes and inside the machine
- Longer rinse cycles needed to clear soap
- Possible errors or shutdowns in modern (especially HE) machines due to excess foam detection
In high-efficiency washers, which use very little water, a small amount of dish soap can lead to an overwhelming amount of bubbles—a small capful can result in overflowing foam.
What If I Accidentally Used Dish Soap in the Washing Machine?
Don’t panic—this happens more often than you think. Here’s what to do step-by-step:
- Stop the Machine Immediately
-
Pause or stop the wash cycle if you catch the excess suds early.
-
Remove the Excess Suds
-
Scoop out as many bubbles and suds as possible with a cup or towel.
-
Run a Rinse and Spin Cycle
- Rerun the washer on a rinse and spin cycle (use cold water).
-
Avoid adding more detergent or soap.
-
Repeat If Necessary
- It might take several rinse cycles to clear out all the soap.
-
If possible, leave the washing machine door/lid open to help dry out excess moisture and prevent mold.
-
Check Clothes for Residue
- If clothes still feel soapy, run an additional rinse with just water.
Are There Any Benefits to Using Dish Soap?
While dish soap isn’t meant for washing machines, some people have hand-washed clothes with a few drops of dish soap in emergencies. Here’s what to know:
- Dish soap is effective on some stains (especially greasy spots).
- Only a drop or two should be used if hand-washing in a basin or sink.
- Make sure to rinse thoroughly with plenty of water.
Warning: Even for hand-washing, too much soap can make rinsing fabrics difficult.
Practical Tips and Better Alternatives When You’re Out of Laundry Detergent
If you’re in a bind with no laundry detergent, here’s what you can use instead—safely:
1. Use Less Than a Teaspoon (If You Must)
- If you’re absolutely out of options and must use dish soap, use no more than one teaspoon for a full load.
- Dilute the soap with water before adding it to the washer.
-
Avoid for HE machines or front-loaders.
-
Note: Only do this if you do not have any other safe alternative.*
2. Safe Swap Options
- Baking Soda: Add half a cup directly to the drum to freshen and clean clothes.
- Borax: Use as directed (usually about ¼ cup per load).
- Shampoo (without conditioner): Use sparingly and only for hand-washing—never in a machine.
- Laundry bar soap: Grate a small amount for hand-washing only.
3. Plan Ahead
- Always keep a spare small bottle or box of laundry detergent for emergencies.
- Purchase travel-sized packets for backup.
4. Clean Up After Accidents
- Thoroughly wipe down your machine and the surrounding area if dish soap has overflowed.
- Remove and rinse detergent drawers if they’ve filled with suds.
Common Myths and Mistakes About Using Dish Soap
Let’s clear up a few frequent misconceptions:
-
Myth: “Dish soap gets dishes spotless, so it should do the same for clothes.”
- Fact: The technology behind laundry and dish cleaning is different. Their foam levels, chemical makeup, and rinse rates aren’t interchangeable.
-
Myth: “A little suds never hurt anyone.”
- Fact: Suds can hide in machine parts and cause slow but expensive damage over time.
-
Mistake: “I can just use more water and the suds will wash away.”
- Fact: Sometimes adding more water creates even more bubbles, worsening the mess.
Protecting Your Washing Machine & Clothes: Best Practices
To keep both your laundry and your machine in good shape:
- Always use detergents specifically made for washing machines.
- HE washers must use HE-specific detergents to avoid damage and inefficiency.
- Check your machine’s manual before trying alternative cleaning agents.
- Clean your washer monthly to prevent buildup from soaps or lint.
- Keep your machine’s warranty intact by following manufacturer instructions.
The Bottom Line
Dish soap works wonders on greasy dishes, but it’s the wrong tool for laundry—especially in a washing machine. Using it risks creating a foamy mess, damaging your washer, and leaving soap residue on your clothes. There are better, safer ways to clean your laundry if you run out of detergent. Always prioritize laundry detergents over substitutions. If you accidentally used dish soap, don’t worry—just follow the cleanup steps promptly.
Frequently Asked Questions (FAQs)
1. Can I use dish soap to hand-wash clothes?
Yes, but use with caution. Only use a tiny drop of mild, unscented dish soap and rinse clothes thoroughly. Too much soap can make rinsing difficult and leave residue.
2. Will dish soap ruin my washing machine?
Regularly using dish soap can damage your washer’s internal components or cause blockages. One accidental use usually doesn’t ruin your machine, but clean thoroughly afterwards.
3. What happens if there are too many suds in my washing machine?
Excess suds can overflow, spilling onto the floor, and potentially damage the machine’s electronic and mechanical parts. Always stop the machine and rinse out the soap as soon as possible.
4. Are there laundry detergents that are safer for sensitive skin or allergies?
Yes, look for detergents labeled “hypoallergenic,” “fragrance-free,” or formulated for babies. These are less likely to irritate sensitive skin compared to regular soaps, including dish soap.
5. What can I use if I run out of laundry detergent at home?
Try baking soda or borax in the washing machine, or hand-wash small items with a very small amount of mild soap. Avoid using dish soap, body wash, or shampoo in the washing machine.
