Why Is My Shower Glass Always Cloudy?
Dear Sage,
"My shower glass looks permanently foggy. I've scrubbed it with everything under the sink, I've tried the vinegar thing off the internet, and it comes up slightly better for a day and then looks exactly the same. The shower is four years old. Is this just what happens, or am I doing something wrong?"

Dear Scrubbed Out,
You're not doing anything wrong, and you're not going to scrub your way out of this one. What's on that glass almost certainly isn't dirt, which is why cleaning it like dirt hasn't worked.
There's also a part of this answer you won't like, so I'll put it in the middle rather than hide it at the end.
It's the Water, Not the Shower
Most of Central Florida drinks from the Floridan Aquifer, which runs through limestone. Limestone is calcium carbonate, and the water arrives at your house carrying a good deal of it in solution.
Every time you shower, a film of that water sits on the glass and evaporates. The water leaves. The minerals don't. Do that twice a day for four years and you have thousands of microscopically thin mineral layers bonded to the surface — plus soap scum, which is what happens when soap meets those same minerals and turns into a waxy solid rather than rinsing away.
So the haze is a deposit sitting on top of the glass, and in the worst cases a change to the glass itself. Those two need completely different answers.
Scale Comes Off. Etching Doesn't.
Scale and soap scum sit on the surface. They're stubborn, but they are removable, and the right approach takes them off properly rather than temporarily.
Etching is different. Minerals left in contact with glass for years slowly pit the surface, and acidic cleaners used repeatedly accelerate it. Once glass is etched, the cloudiness is the texture of the glass. There is no cleaner, no paste and no technique that reverses it, because there is nothing to remove.
Here's the test. Wet the glass. If the haze disappears while the glass is wet and returns as it dries, it's deposit and it will come off. If it looks the same wet as dry, that section is etched, and the honest answer is that it needs replacing or living with.
Four years is right in the window where it's usually mostly deposit with some etching at the bottom of the panel, where water sits longest.
What Actually Works
An acidic descaler, and time. Mineral scale is dissolved, not scrubbed. A proper limescale remover needs to sit on the glass and work — several minutes, not several seconds. Most people spray and wipe immediately, which is why they conclude it doesn't work.
Keep it wet while it dwells. A product that runs off or dries out has stopped working. Reapply, or lay a wet cloth against the glass.
Then a non-scratch pad, with light pressure. The chemistry does the work; the pad only lifts what's already loose.
Expect two or three passes on a four-year build-up. Each one takes a layer. One pass on years of scale will always disappoint.
Vinegar is mildly acidic and works on light, recent scale. On four years of it, it's underpowered, which matches exactly what you described.
What Makes It Worse
Abrasive powders and scouring pads. They take the haze down for a fortnight by scratching the surface, and those scratches hold minerals better than smooth glass did. The next build-up is faster and harder.
Razor blades. Widely recommended online. They'll remove scale and they'll also put permanent fine scratches in glass that has any coating on it.
Leaving an acidic product on overnight. This is how etching happens faster. Dwell time means minutes.
Using glass descaler on the stone next to it. If you have marble or travertine anywhere near that shower, acid will etch it on contact. Mask it or keep well away.
Why Your Cleaner Doesn't Fix It
Worth saying plainly, because people assume it's being skipped. A standard clean includes cleaning the shower. It doesn't include a multi-pass descaling treatment on four years of mineral build-up, because that's forty minutes on one panel of glass and the visit isn't scheduled for it.
It's a restoration job rather than a cleaning job, and it should be quoted as one. Ask for it specifically — it's the same distinction we drew in the spots that get missed in a house cleaning.
Keeping It Clear Afterwards
Once it's back to clear, staying clear is almost entirely one habit.
Squeegee the glass when you get out. Ten seconds. If the water isn't sitting there evaporating, it can't leave anything behind. This single habit does more than every product on the shelf combined.
Leave the door open and the fan running. Faster drying, less deposit, and far less mildew in the grout while you're at it.
Consider a glass sealant. It fills the microscopic pores so water beads and runs off. It wears away and needs redoing a few times a year, but on fresh glass it works well.
Switch to liquid body wash. Bar soap contains talc and fats, which is what makes soap scum the sticky layer it is.
Sage's Final Thoughts
Do the wet test first, because it tells you whether you're solving a cleaning problem or accepting a glass problem. Most four-year-old screens are mostly deposit, and deposit comes off with an acidic descaler, real dwell time and two or three passes.
Then buy a squeegee and hang it in the shower. It's a dull answer, but it's the one that holds.
And be wary of anyone who promises your glass will come up like new without having looked at it. Some of it may be etched, and telling you otherwise just moves the disappointment to the end of the job.
