Can You Use Regular Detergent in an HE Washer Safely?

Ever stand in your laundry room staring at a pile of detergent bottles and wonder, “Can I just use what I have and call it a day?” With rising costs and less patience for waste, squeezing value out of what’s already on hand just makes sense. But when it comes to high-efficiency washers, a little shortcut can turn into a bigger headache. Before you pour, here’s what actually works, what’s risky, and how to stretch your supplies without shortening the life of your machine.

If you’ve ever wondered what the difference is between regular laundry detergents and those designated as “High Efficiency” or HE, or if they’re interchangeable, and whether you could make your own to cut the cost… you are not alone. These questions show up in my mailbox all the time.

Dear Mary: First, thank you for your column. I love it! I just inherited several bottles of regular laundry detergent. I have a high-efficiency front-load washer. Is there a way to use or modify regular detergent for HE use?

Dear Christin: You’re asking a smart question and one I hear often.

Traditional washing machines can use up to 35 gallons of water per load, while high-efficiency (HE) machines (like my the LG Front Load Washer with TurboWash 360) use as little as 13 gallons. That’s not just a fun fact. That’s the whole reason this matters!

HE washers rely on low water levels and tumbling action, not a big tub full of suds. That’s where things start to go sideways with regular detergent.

Why Regular Detergent Can Backfire in an HE Washer

Regular detergent is designed to create lots of suds. In a traditional washer, that works just fine because there’s plenty of water to rinse it all away.

In an HE machine, not so much. With less water in the mix, those extra suds don’t fully rinse out. Instead, they linger and that’s where the trouble begins.

Over time, that leftover detergent can:

• Leave behind stubborn odors
• Build up inside the drum, hoses, and seals
• Make your washer work harder than it should
• Trigger extra cleaning cycles (using more water and energy)
• Lead to repairs you didn’t plan for

That “something smells off” situation? This is often where it starts.

I know. It feels smart to use what you already have. Most of the time, it is. But this is one of those cases where trying to squeeze every last drop out of a product can quietly cost you more in the long run. A little restraint here really does save a lot of hassle later.

So… Can You Use It Anyway?

Your owner’s manual is going to say no. And if something goes wrong, that could come back to haunt your warranty.

That said, I’m going to be honest with you. I have used regular detergent in an HE machine from time to time. But I was very careful about it.

If You Decide to Use It (Read This First)

When I say “use less,” I mean a lot less.

• About one-fourth of what you’d normally use
• Measured in tablespoons, not capfuls
• Diluted in water first before adding it

That last step matters more than people think. It helps prevent a concentrated blob of suds from forming right out of the gate.

Would I do it again? Yes. Would I recommend doing it all the time? No. This is a “get by when you need to” solution… not a long-term solution.

Before You Pour Another Capful…

I completely understand the urge to use what you already have. That’s just good sense. But in this case, you might be better off thinking a step ahead.

Here are a few smart ways to put it to use:

• Pass those bottles along to someone with a traditional washer
• Donate them to a shelter or community group
• Keep a small amount for hand-washing or stain treatment

That way, nothing goes to waste and your machine stays out of harm’s way.

Want a Budget-Friendly HE Option?

If your goal is to save money without risking your machine, homemade HE detergent is a smart way to go. I know… years ago I would have rolled my eyes at the idea. But once I did the math (and saw the results), I changed my tune.

You’ve got two solid options. Both give you the same big win: clean clothes, fewer additives, and a noticeable drop in your cost per load. It really just comes down to what fits your routine better: liquid convenience or powdered simplicity.

Liquid Homemade Laundry Detergent (My Go-To)

This is the one I reach for most often, especially with HE machines. It’s simple to make, easy to use, and already diluted, which means it plays nicely with low-water washers. No guessing, no clumps, no drama.

You’re looking at just a few basic ingredients and pennies per load and it handles everyday laundry like a champ.

Powdered Laundry Detergent (Fast & Frugal)

If you prefer something even quicker to make, the powdered version is hard to beat. It stores well, lasts a long time, and is incredibly cost-effective. Just scoop and go.

The only thing to keep in mind: with HE machines, you’ll want to add it directly to the drum and use a light hand so it dissolves properly.

A Few Habits That Make a Big Difference

You don’t have to do much to keep an HE washer running well, but what you do matters:

• Use the right amount of detergent (more is not better)
• Leave the door open after a load to let things dry out
• Run a cleaning cycle once a month
• Give the seals and detergent drawer a quick wipe now and then

These take just a minute or two but can extend the life of your machine significantly.

Bottom Line

Yes, you can use regular detergent in a high-efficiency washer in a pinch. I’ve done it. But it comes with strings attached and it’s not something you want to rely on long-term.

If you want your machine to last, smell fresh, and do its job without complaint, it’s worth sticking with what it was designed to use.

Sometimes the simplest path really is the smartest one.
