What it is, how it works, what BacLock® actually does, how to use it correctly and why this little cloth can completely change the way you clean.
The quick answer
Norwex microfiber is a densely woven cleaning textile made from extremely fine split fibers. Used damp, the fibers lift, grab and trap dirt, grease and tiny particles so they can be physically removed from a surface. Used dry, the cloth creates a static charge that attracts dust.
Norwex microfiber is not a disinfectant. It does not need to kill what is on the surface in order to clean the surface. It picks it up, holds onto it and removes it.
What is Norwex? How does it work? And what makes it so different from the stack of cleaning cloths you can buy almost anywhere?
I have answered those questions thousands of times, and I still love answering them because microfiber is where Norwex really begins.
Yes, Norwex makes laundry products, household cleaners, personal-care products and all kinds of useful things. But the product that changes the way most people think about cleaning is microfiber.
It is a cloth you can use on your counters, your bathroom, your desk, your child’s school table, your car and, yes, the airplane tray table and seat that you would rather not think too deeply about. It looks simple. The science and construction behind it are not.
And before we go any further, I want to clear up the most important point:
Norwex microfiber cleans by removing. BacLock® works inside the cloth. Those are two different jobs.
What Is Norwex Microfiber?
Microfiber is a textile made from fibers that are far finer than ordinary cotton fibers. Norwex microfiber is a blend of polyester and polyamide. During manufacturing, those fibers are split into extremely fine strands, creating millions of tiny spaces that can grab and hold onto what you are trying to remove.
That matters because a cloth does not clean simply because it is wet. It cleans because of the way the fiber interacts with the surface.
A smooth cotton fiber can push and smear soil around. A split microfiber has edges, channels and an enormous amount of surface area. Those tiny fibers can get underneath particles, lift them away from the surface and pull them into the cloth.
Cleaning with a basic cotton cloth can be a little like trying to pick up a pile of crumbs with a beach ball. Norwex microfiber behaves more like a tiny shovel with millions of places to hold what it picks up.
How Does Norwex Microfiber Work?
There are two simple ways to use it, and they work differently.
Used damp – it lifts, traps and removes
When damp microfiber moves across a surface, the split fibers make close contact with that surface. They lift and trap soil, grease, crumbs, dust and other small particles inside the cloth rather than simply pushing everything ahead of it.
Norwex states that, when its microfiber is used and cared for properly, it can physically remove up to 99% of bacteria from a surface using only water. The key word is remove.
Used dry – it attracts dust
When used dry, the fibers rubbing together create a static charge. That helps attract and hold dust, pet hair, dander and other loose particles instead of sending them floating right back into the air.
Water is not doing all the work. The water helps the cloth move, make contact and release soil during rinsing. The microfiber construction is the cleaning tool.
What Makes Norwex Microfiber Different?
I will try to be brief here, but I could go on for days.
1. Fiber size
Ordinary microfiber can be fine. Norwex takes it much further. Current Norwex science materials describe the split fibers as approximately 1/200 the thickness of a human hair. Finer fibers can make closer contact with a surface and reach smaller particles.
2. Density
An EnviroCloth contains an extraordinary amount of microfiber packed into one cloth. Suzanne’s original explanation compared the unraveled fiber length to stretching from Canada to Mexico. The practical point is simple – there are a lot of fibers available to grab and hold what you pick up.
3. BacLock®
Many Norwex microfiber products contain BacLock®, an antimicrobial agent embedded in the fibers. BacLock® helps inhibit bacterial growth and odor inside the cloth as it dries.
Those three characteristics work together. Fine fibers help the cloth reach and lift smaller particles. Dense construction gives the cloth more places to trap them. BacLock® helps protect the cloth between uses.
That does not mean every Norwex cloth is right for every job. Weave, texture and purpose still matter. A polishing cloth, a scrub mitt and an EnviroCloth may all be microfiber, but they are designed to perform differently.
What Is BacLock® – and What Does It Actually Do?
This is the part people misunderstand most often.
BacLock® is not what cleans your counter. The microfiber cleans the counter by physically removing material from the surface.
BacLock® is an antimicrobial agent embedded in certain Norwex microfiber products. It is designed to inhibit bacterial growth and odor within the cloth as the cloth dries. Norwex describes this as the cloth beginning to self-purify within 24 hours.
| Microfiber’s job | BacLock®’s job |
|---|---|
| Lifts, grabs, traps and removes soil and particles from the surface. | Helps inhibit bacterial growth and odor inside the cloth between uses. |
| Works while you are wiping. | Works in the cloth as it dries. |
| Cleans the surface mechanically. | Does not disinfect the surface. |
You still need to rinse the cloth thoroughly, hang it open to dry and launder it when it is heavily soiled, greasy, used for a high-risk mess or no longer rinses clean.
Does Norwex Microfiber Disinfect?
No. Norwex microfiber is not a disinfectant, and I do not want you using the words clean and disinfect as though they mean the same thing.
Cleaning removes. Disinfecting uses a registered product to kill specified microorganisms when the product is used exactly according to its label, including the required wet-contact time.
For routine household cleaning, physical removal is often exactly what you need. You wipe the surface and take the mess away instead of leaving a chemical product sitting on the surface for a required amount of time.
There are also situations where disinfection is appropriate – illness in the home, certain bodily-fluid messes, food-safety concerns or guidance from a healthcare or public-health professional. In those situations, clean first and then use an appropriate EPA-registered disinfectant according to the label.
Use microfiber for the everyday work of keeping a home clean. Use a disinfectant when the situation actually calls for disinfection. A good cleaning system should help you use the right tool – not pretend one tool does everything.
How to Use Norwex Microfiber Correctly
The cloth is easy to use, but a few details make a big difference.
- Wet the cloth thoroughly. Run it under water so the fibers are evenly damp.
- Wring it out well. For most routine cleaning, damp is better than dripping wet. Too much water can leave streaks and makes it harder for the cloth to hold what it picks up.
- Fold it into fourths. This gives you eight usable cleaning surfaces and helps you keep track of which side is clean.
- Keep the cloth flat against the surface. A flat folded cloth provides better contact than a loose wad in your hand.
- Wipe with intention. Work from the cleaner area toward the dirtier area. Use an “S” pattern on larger surfaces so you are not repeatedly dragging the same soil back over a cleaned section.
- Turn to a clean side as each section becomes soiled. Do not keep wiping the whole kitchen with one dirty face of the cloth.
- Rinse thoroughly after use. Agitate the cloth under running water until the water runs clear, then wring it out.
- Hang it open to dry. Do not leave a damp cloth balled up in the sink or sitting in a pile.
Start with one room and one cloth. Learn what “damp enough” feels like, learn the fold and learn when to turn to a clean side. Confidence comes quickly when you stop trying to learn the entire catalog at once.
Where Can You Use Norwex Microfiber?
One reason the EnviroCloth becomes a daily-use product is that it can replace a surprising number of single-purpose wipes and sprays.
- Kitchen counters and cabinet fronts
- Tables, desks and high chairs
- Bathroom counters, sinks and fixtures
- Doors, light switches and fingerprints
- Refrigerator shelves and appliance exteriors
- Car interiors
- Dusting furniture, baseboards and electronics with an appropriate dry cloth
- Travel surfaces such as hotel rooms and airplane tray tables
For glass, mirrors and shiny surfaces, I usually follow the damp cleaning cloth with a dry polishing cloth designed for that job. The first cloth removes the mess. The second cloth removes the remaining moisture and gives you the streak-free finish.
When Water and Microfiber Are Not Enough
I love Norwex microfiber. I also do not believe in pretending it is magic.
Microfiber may need help when you are dealing with:
- Heavy grease or a built-up oily film
- Mineral deposits and hard-water scale
- Burned-on food
- Soap scum that has accumulated over time
- Stains that require a specific chemistry or enzyme
- A situation that specifically requires sanitizing or disinfecting
In those cases, use the correct supporting product and technique. Sometimes that means an enzyme, a degreaser, a descaler, a scrub product or a disinfectant. The goal is not to prove that one cloth can do every job. The goal is to make routine cleaning simpler and use additional products only when the job truly needs them.
How to Care for Norwex Microfiber
The fastest way to become disappointed in a good microfiber cloth is to load the fibers with residue. Proper care keeps all those tiny spaces open and working.
After light use
- Rinse the cloth very well under warm running water.
- Use a small amount of suitable soap when needed, then rinse until no soap remains.
- Wring it out and hang it fully open to dry.
When it needs laundering
- Wash with a detergent that rinses clean and does not leave heavy residue.
- Wash microfiber with lint-free items when possible.
- Avoid fabric softener and dryer sheets. They coat the fibers and reduce performance.
- Avoid chlorine bleach unless current product instructions specifically allow it.
- Follow the current Norwex care label for the specific item.
When it needs a deeper reset
If a cloth is greasy, smelly, repelling water or leaving streaks, it may have product buildup trapped in the fibers. A deeper cleaning with a microfiber-safe product can help remove oils, minerals and detergent residue.
Before deciding the cloth “doesn’t work,” ask what may be inside the cloth. Fabric softener, too much detergent, grease, body oils and lint can all interfere with performance.
The Most Common Norwex Microfiber Mistakes
Using the cloth too wet
A dripping cloth often leaves excess water and streaks. Wring it out more than you think you need to.
Wiping too long with one dirty side
Folding gives you clean surfaces for a reason. Turn the cloth as it becomes soiled.
Leaving it bunched up while damp
Rinse it and hang it open. BacLock® is helpful, but proper drying still matters.
Washing it with linty items
Microfiber is designed to grab tiny particles. That includes the lint from towels and fuzzy blankets.
Using fabric softener or dryer sheets
Coating the fibers can block the tiny spaces that make the cloth effective.
Believing BacLock® disinfects the surface
It does not. Microfiber cleans the surface. BacLock® helps inhibit bacterial growth and odor in the cloth.
Expecting one cloth to replace every cleaning product
Norwex microfiber can dramatically reduce the number of products you use. It does not eliminate the need for good judgment.
Is Norwex Microfiber Worth It?
For the right person, yes. But “worth it” is not really about whether a cloth costs more than a pack of bargain microfiber.
The better questions are:
- Will you use it regularly?
- Will it replace disposable wipes, paper towels or several routine sprays?
- Will you learn the simple technique that makes it work well?
- Will you care for it properly?
- Will simplifying your routine help you clean more consistently?
I have watched people buy a cloth, use it incorrectly twice and decide it is overrated. I have also watched families use the same basic system for years because it made everyday cleaning faster and easier.
The product matters. The habit matters just as much.
My Honest Bottom Line
Norwex microfiber is not a magic cloth, and it is not a disinfectant.
It is a very well-constructed cleaning tool that uses extremely fine, dense fibers to physically lift, trap and remove dirt and small particles from a surface. BacLock® helps inhibit bacterial growth and odor inside certain cloths as they dry. When you use the cloth correctly, rinse it well and keep the fibers free from residue, it can simplify an enormous amount of everyday cleaning.
That is what makes it unique to me.
Not that it lets us stop thinking about cleaning – but that it gives us a simpler, reusable way to do most of it well.
Frequently Asked Questions
No. It cleans mechanically by lifting, trapping and removing material from the surface. When a situation requires disinfection, use an appropriate EPA-registered disinfectant and follow its label directions.
BacLock® is the antimicrobial agent embedded in certain Norwex microfiber products. It helps inhibit bacterial growth and odor within the cloth as it dries. It does not disinfect the surface being wiped.
For many routine household surfaces, yes. The microfiber is the tool doing the physical cleaning. Water helps the cloth move across the surface and helps you rinse away what it collects.
The cloth may be too wet, overloaded with soil or coated with detergent, grease or fabric-softener residue. Wring it out thoroughly, turn to a clean side and deep-clean the cloth if buildup is suspected.
Rinse thoroughly after each routine use and hang it open to dry. Launder it whenever it is heavily soiled, greasy, used for a high-risk mess or no longer rinses clean. Follow the care label for the specific product.
No. Fiber fineness, splitting, density, weave, durability and intended use can vary widely. Two cloths can look similar and perform very differently.
