The Windows in My Neighbour’s House Were So Clean I Thought She Had Hired a Professional

When I asked what product she used, her answer made me cancel my own window cleaning service just a few weeks later.

I have far more glass in my house than I realized when we built it. Sliding doors in the living room, large windows at the front, more glass near the kitchen and a wide door leading out to the backyard.

When we chose all of that, I was only thinking about one thing: natural light. I wanted the house to feel bright during the day and for us to be able to look out at the garden from practically any room.

What I didn’t consider was who was going to keep all that glass clean.

At first, I tried doing it myself. Glass spray, paper towels, ordinary microfibre cloths, a squeegee, a bucket — I’ve probably tried almost everything you can find in the cleaning aisle.

And the result was always the same. As soon as I finished, the glass looked great.

Then the light would change.

The afternoon sun would stream into the living room and suddenly there were marks I could have sworn weren’t there five minutes earlier. Cloth streaks, smudges, little spots, that slightly hazy appearance that only becomes obvious when you look at the glass from a certain angle.

I would go back over the same panel, apply more product and clean it again. Sometimes it improved. Sometimes it got worse.

After a few months of this, I came to the conclusion that I simply didn’t know how to clean windows properly. So I did what a lot of people do: I started paying someone to do it for me.

It was $250 per visit. By the end of the year, I had spent nearly $1,500 just to have clean glass for a few weeks.

Because the result was excellent on the day of the cleaning. And that was it.

Before long, the fingerprints were back. The dog would press its nose against the door, dust would build up on the outside, and a few weeks later I’d already be looking at the glass thinking: “I can’t believe I’m going to have to clean all this again.”

So I was paying for the service and still cleaning with spray between visits.

That went on for quite a while. Until I noticed something strange at my neighbour Susan’s house.

I could see her garden as if there were no glass in the door

It was one afternoon when I went over to her place. We were chatting near the kitchen when I looked at the large glass doors leading out to the backyard.

And they were unbelievably clean.

I’m not talking about the kind of clean that looks good from a distance. The glass practically disappeared. There was none of that haze that shows up when the sun hits it, no circular cloth marks, no streak where one wipe had overlapped another.

The door looked open.

I asked, “Did you have your windows cleaned this week?”

Susan laughed. Then she said she hadn’t called a window cleaner in months.

I thought she was exaggerating. Her house had just as much glass as mine — maybe even more. So I asked how she kept it looking like that.

Susan went to the laundry room and came back holding a cloth.

That was it. One large grey cloth.

I kept waiting for the rest. Some special product, a professional spray, some kind of equipment. But there was nothing else.

“I wet this with water, wring it out and wipe the glass.”

I’ll admit, I thought it sounded ridiculous. I had an entire drawer full of microfibre cloths at home, and none of them did that.

Then she wet the cloth and wiped a mark off the bottom corner of the door. One wipe. Then another.

The mark simply disappeared. And more importantly, it didn’t leave behind the kind of streak that normally shows up once the water dries.

Maybe the problem wasn’t the dirt. Maybe it was what I was using to remove it

According to her, after trying different methods, she realized that many glass cleaning products can leave a very fine residue on the surface. You finish cleaning and think it looks perfect — but when the lighting changes, those little marks become obvious.

That made complete sense to me. It was exactly what happened in my house: in the morning, the glass looked perfect; in the afternoon, there were marks everywhere.

For years, my reaction had been to put even more product on the glass. More spray, more paper, more wiping.

In reality, I was making a task that should have been extremely simple much more complicated.

The cloth Susan was using was the Vitrax Clear, and the way it works is completely different. Instead of relying on a product to dissolve the dirt and then trying to remove everything before it dried, she simply used water and the cloth itself.

No spray. No paper towels. No squeegee. And most importantly, nothing left behind on the glass after the water evaporated.

That was enough to make me curious. I asked if I could take one of the cloths home and try it myself.

I started with the worst door in the house

If it worked there, it would work anywhere. It was the sliding door we use to get into the backyard: fingerprints at hand height, marks from the dog along the bottom, dust on the outside and, against the light, that film I could never completely remove.

I wet the Vitrax Clear under the tap, wrung it out well, and wiped from top to bottom.

The first thing I noticed was the size. The cloth measures 60 x 40 cm, so I could cover a much larger section of glass with each movement. Instead of making small circular wipes all over the panel, I used long strokes — one section, then the next.

In less than a minute, I had finished the entire door.

I took a few steps back. The glass was clean.

But that still didn’t impress me, because my sprays also seemed to work right after cleaning. The real test would come a few hours later.

I waited for the sun to hit the glass directly

Around the middle of the afternoon, the light started coming into the living room. Normally, this was the moment when I discovered everything I had done wrong.

I grabbed my coffee and went to look at the door. I expected to find at least a few smudges, maybe some dried streaks, perhaps a mark around the edges.

I couldn’t find anything.

I changed position. Looked from the side. Moved closer. Went outside to look at the glass from the other side.

It was still crystal clear.

It wasn’t just that the door looked “cleaner”. It had exactly the appearance I associated with the first few minutes after the professional had finished the job — except I had done it with water and a cloth.

So I did another window. Then another. And another.

Before I knew it, I was walking around the house looking for glass surfaces just so I could test it.

Why this cloth doesn’t behave like the others I had already used

I always thought microfibre was simply microfibre. It isn’t quite that simple.

One of the differences between fabrics is density, normally measured in GSM — grams per square metre. Many household cloths are relatively thin; the Vitrax Clear uses a much denser fabric, with 600 GSM.

In practical terms, there is much more fibre working across the surface. This helps the cloth pick up dirt, grease and moisture instead of simply pushing them around the glass.

The ironic part is that, for years, I had tried to solve the problem by adding things. A better spray, another type of cloth, special paper, more product, more technique.

The solution was exactly the opposite: remove almost everything.

Now there’s a Vitrax Clear near the back door. I wet it with water, wring it out, wipe the glass, wash the cloth when needed and reuse it. No strong chemical smell, no piles of paper towels, no cupboard full of different bottles for every surface.

My husband started cleaning the doors without me asking

That may have been the most unexpected part. He had always been the kind of person who would see a mark on the glass and just keep walking.

One day I noticed the door was clean and asked if he had wiped it.

“The dog rubbed against it. The Vitrax Clear was right there.”

That was when I realized what had really changed. It wasn’t just the quality of the cleaning — the job had stopped feeling like a job.

When something takes seconds and there’s no way to get it wrong, you just do it. It’s very different from thinking about buckets, cleaning products, paper towels and twenty minutes of work.

Now I clean the kitchen door while I’m waiting for my coffee to be ready. The dog marks don’t build up for days, and that dull-looking glass that used to appear gradually has simply stopped being part of the house.

The cloth I’m using is the Vitrax Clear. It’s the same model I first saw at Susan’s house.

It measures 60 x 40 cm, features a high-density fabric and was designed to clean surfaces such as windows and glass doors using only water.

If you have a lot of glass at home and you’re tired of finishing the cleaning only to discover new smudges when the sun changes position, it’s worth taking a look.

And there are two things about the current offer that are worth mentioning. Readers of this article can get up to 56% off with free shipping, and they also offer a 30-day trial period.

In other words, you can do exactly the same test I did — clean your worst glass door, wait for the sun to hit it and check the result with your own eyes.
