If laundry isn’t rinsed properly, leftover detergent and residue can stay in the fabric. That can make clothes feel stiff or scratchy, cause skin irritation for some people, trap odors, and shorten the life of your clothes over time. For most households, it’s not a hygiene emergency — but it can quietly create annoying problems that add up.
This is one of those questions people Google because something feels off: towels that smell clean but don’t feel clean, clothes that itch for no obvious reason, or laundry that comes out looking dull even though you’re “doing everything right.”
Let’s talk through what actually happens, what doesn’t matter as much as you’ve been told, and when rinsing really is worth paying attention to.
What “not rinsing properly” actually means
Most modern washing machines rinse clothes well enough on a normal cycle. Problems usually show up when:
- Too much detergent is used
- The machine is overloaded
- Quick or eco cycles don’t rinse thoroughly
- Hard water causes detergent to cling to fabric
- Fabric softener or scent boosters are added on top of detergent
In other words, this isn’t usually about skipping a rinse cycle entirely. It’s about residue building up slowly without you realizing.
What can happen if detergent isn’t fully rinsed out
1. Clothes can feel stiff, scratchy, or waxy
This is the most common sign. Detergent residue coats the fibers, especially on towels, bedding, and workout clothes.
Instead of feeling clean and soft, fabrics can feel:
- Crunchy when dry
- Slightly greasy or waxy
- Rough against the skin
People often assume this means they need more detergent or fabric softener, which actually makes the problem worse.

2. Skin irritation becomes more likely
If you’ve ever had:
- Itchy clothes with no visible rash
- Redness after wearing freshly washed items
- Sensitivity that comes and goes
…detergent residue is a common (and often overlooked) cause.
This matters more for:
- Babies and kids
- People with eczema or sensitive skin
- Underwear, bras, socks, and bedding
It doesn’t mean detergent is “toxic.” It just means your skin is in contact with soap longer than it needs to be.
3. Towels and clothes can start to smell worse
This one surprises people.
Leftover detergent can:
- Trap body oils and bacteria
- Prevent water from fully flushing fabrics
- Create buildup that holds odor instead of releasing it
So you get that frustrating situation where laundry smells clean coming out of the dryer… then smells musty or sour once it’s been worn or used.
This is especially common with towels.

4. Clothes don’t get as clean over time
Detergent buildup can actually block detergent from doing its job in future washes.
Over time, fabrics may:
- Look dull or gray
- Hold onto stains
- Feel heavier or less breathable
This is subtle and gradual, which is why people often blame the washing machine or water quality instead.
5. Washing machines can get gunky too
If detergent isn’t rinsing out of clothes, it’s often not rinsing out of the machine either.
That buildup can:
- Stick inside the drum and seals
- Trap lint and moisture
- Contribute to that “dirty washer” smell
This doesn’t happen overnight, but it’s one reason machines benefit from occasional cleaning.
What Happens If You Don’t Clean Your Washing Machine?
Why people think extra rinsing is always necessary
A lot of laundry advice comes from marketing, habit, or fear — not real-world need.
Marketing has trained us to overuse products
Laundry products are designed to:
- Smell strong
- Create visible suds
- Promise “extra” benefits
But more suds don’t mean cleaner clothes. In fact, modern machines are built to use less water and less detergent.
Using more product than needed almost guarantees poor rinsing.
Old habits stick around
Many people learned laundry habits from:
- Older machines that used lots of water
- Hand-me-down advice
- “This is how my mum did it”
Those habits don’t always translate well to today’s machines.
Fear-based advice exaggerates the risk
You’ll sometimes see warnings that unrinsed laundry is “dangerous” or “full of chemicals.” That’s not helpful or accurate.
For most households:
- This is about comfort, not safety
- It’s a quality issue, not a crisis
- Small adjustments usually fix it
What actually matters in real households
Here’s what tends to make the biggest difference — without overthinking it.
Detergent amount matters more than rinse cycles
Using too much detergent is the number one cause of rinsing problems.
Most people can:
- Use half the recommended amount
- Go even lower for soft water or small loads
If clothes don’t smell dirty, they’re clean.
What Happens If You Use Too Much Detergent?
Load size affects rinsing
Overloaded machines can’t rinse properly because water can’t circulate.
If clothes come out:
- Twisted together
- Still sudsy
- Heavy and stiff
…try smaller loads before adding extra rinse cycles.
Fabric softener makes rinsing harder
Fabric softener leaves a coating by design. That coating:
- Traps detergent residue
- Reduces absorbency
- Makes towels and bedding worse over time
Many people see improvement just by stopping fabric softener altogether.
What Happens If You Stop Using Fabric Softener?
When proper rinsing really is worth paying attention to
Extra care with rinsing is helpful in a few situations.
If someone has sensitive skin
Babies, toddlers, and people with eczema or allergies often do better with:
- Less detergent
- An extra rinse for underwear or bedding
This doesn’t need to apply to every load forever.
If towels or gym clothes smell clean but act dirty
When fabrics smell fine but:
- Get smelly quickly
- Feel rough or slimy when wet
That’s often residue buildup. A proper rinse (or a temporary extra rinse) can reset things.
If you’ve been overusing detergent for a while
If you’re correcting a habit, adding an extra rinse for a few loads can help flush out buildup — then you can go back to normal cycles.
Practical advice that actually helps
You don’t need to micromanage your laundry routine. Try this instead:
- Use less detergent than the label suggests
- Skip fabric softener and scent boosters
- Don’t overload the machine
- Add an extra rinse only if clothes feel soapy or stiff
- Wash towels and bedding separately if problems persist
For most people, these changes solve the issue without adding more work.
