The short answer
Glass that faces the sea gets dirty in weeks because three things land on it together. Wind carries fine droplets of seawater onto the pane, and when the water dries the salt stays. Salt draws moisture out of humid air, so the film stays slightly damp and sticky. Dust then sticks to it and does not blow off. A day or two of sun bakes the mixture into a grey-white haze, and the next breeze starts the cycle again.
For a home in Abu Dhabi that looks straight at the water, that means the outside of the balcony glass and doors needs a proper clean about once a month, the inside faces every two to three months, and the frames, rail and tracks a wipe in between. Homes set back from the water, or facing the city, can stretch that. The reasons, and a table by surface, are below.
IHR Dream Cleaning cleans glass as part of its specialist cleaning services. Window cleaning is booked by the hour. It covers the inside of all the glass, and the outside wherever it can be reached safely from inside, from a balcony or from a step ladder. One cleaner for two hours is AED 65 with your own products, or AED 75 with ours.
What the film on the glass is made of
Four things are in it. Three arrive by themselves and the fourth is usually added by the household.
Salt from the sea
Breaking waves and wind lift tiny droplets of seawater into the air, and an onshore breeze carries them inland. They are too small to see or feel. Where one touches a surface, the water evaporates and leaves a crystal of salt. One day's worth is invisible. A few weeks' worth is a white bloom you can draw a line through with a finger. The nearer the water, and the more directly the glass faces it, the faster the bloom builds.
Humidity that keeps it wet
Salt attracts water. In humid air a salt deposit pulls in moisture and becomes a thin film of brine, which is why sea-facing glass can feel faintly tacky first thing in the morning.
The AC adds to it. For much of the year it keeps the glass cool, so on humid nights moisture from the outside air can condense on the outer face of the pane, the way it does on a cold glass of water. That water runs down through the salt and the dust. When the sun dries it, you get the vertical drip marks that no amount of dry wiping removes.
Dust that sticks
Fine dust is in the air here on most days, and thick in it after a windy one. On dry, clean glass a good part of it blows off again. On a damp salt film it stays, and each layer gives the next something to hold on to. This is why coastal glass goes grey and not just white, and why villas with open sand on one side and the sea on the other get the worst of both.
Minerals from the hose
The fourth ingredient is the one people add themselves. Tap water carries dissolved minerals. When a balcony or a window is hosed down and left to dry in the sun, the water goes and the minerals stay as white spots, often with a ring at the edge of each drop. Garden sprinklers do the same to low glass every day.
These spots are harder to shift than salt, for a simple reason. Salt dissolves in water again. Limescale does not.
Why it is worth staying ahead of it
Fresh salt is the easiest dirt there is, because clean water takes it straight off. The difficulty comes with time, and it is not only the view that suffers.
- Glass. Mineral deposits left on a pane through many cycles of wetting and drying bond to the surface, and can in the end etch it. An etched pane looks cloudy even when it is clean, and cleaning cannot reverse that.
- Frames. Salt sits in the corners and joints of aluminium frames and under the rubber seals. Left there, it dulls the coating and feeds the white, powdery corrosion that aluminium by the sea is prone to.
- Balcony rails and fittings. Stainless steel near the sea develops brown staining where salt is left on it. At first it is on the surface and wipes off. Ignored, it can pit the metal.
- Tracks and rollers. Salt, sand and moisture in a sliding-door track make a gritty paste. The door drags, and the rollers wear.
- Handles and locks. The same film works into moving parts and stiffens them.
One cure for all five
Fresh water, often, and dried off afterwards. That is all a salt deposit needs while it is young. Every recommendation in this guide is a way of doing that before the deposit has had time to harden.
How fast it comes back, and what changes that
No two homes get the same dose. These are the things that set the pace for yours.
- Which way the glass faces. The side that looks at open water takes the most. Glass facing a canal, a creek or the city takes less, and glass on the sheltered side of a building can behave like any inland window.
- How exposed it is. Glass flush with the face of the building is hit directly. Glass at the back of a deep, covered balcony is sheltered from spray, although it still collects the dust that settles in still air.
- The wind. A week of steady onshore wind leaves more salt than a month of calm.
- The season. In the humid months the film stays wet and holds more dust. In the cooler months it is drier, but the doors are open and the balcony is in use, so you notice it more.
- Sand nearby. Open ground, a beach or a building site upwind adds grit to the film.
- Sprinklers and hosing. Any tap water that dries on the glass adds mineral spots on top.
The same pattern along the waterfront
Our notes on the areas we work in record this from one end of the coast to the other. On the Corniche, towers have floor-to-ceiling glass and sea-facing balconies, and sea air and sun are hard on the glass and the soft furnishings behind it. In Al Raha Beach, large windows, balconies and terraces face the canal or the sea, and salt air and sand settle on them quickly. On Saadiyat Island, large areas of glass meet sea air and beach sand, which leave a film fast. In Al Maqtaa, the waterfront villas by the bridge need their windows cleaned against sea salt.
On Al Reem Island most flats have at least one balcony facing either the water or the city, and which of the two it is decides how much salt arrives. Al Bahia has the sea on one side and open sand on the other, so its windows take a salt film with desert dust on top, and many villas there book window cleaning every month or two.
How often to clean each surface
These are starting points for a home that faces the water directly. They are advice, not rules, and the reasons are given so that you can adjust them. If your glass is sheltered or faces inland, begin at the slower end.
| Surface | Starting rhythm | Why |
|---|---|---|
| Outside of sea-facing balcony glass and doors | About once a month | Salt and dust bond harder with every wet and dry cycle |
| Inside faces of the same glass | Every two to three months | Only condensation, fingerprints and indoor film reach it |
| Frames, handles and balcony rail | With every glass clean, and a wipe in between | Salt left on metal stains it and then corrodes it |
| Sliding-door tracks | Vacuumed every week or two in dusty months | Sand and salt paste wears the rollers |
| Glass on the sea side of a villa | Every one to two months | Low glass also catches sprinkler water |
| Exterior walls of a seafront villa | Once or twice a year | The same film forms on paint and stone, more slowly |
How to tell if your rhythm is right
The glass tells you. Two weeks after a clean, run a dry finger across the outside of the pane. If it comes away white or grey and the line you leave is obvious, a month is the right interval, or slightly long. If the pane is still nearly clean at four weeks, try six.
What you are trying to avoid is the stage where the film no longer rinses off and has to be worked off. Up to that point a clean is quick and gentle. After it, the job is slower, needs stronger products, and carries more risk for the glass and the frames.
How that compares with inland homes
Across Abu Dhabi, windows are commonly cleaned every one to three months. Homes by the sea and homes near construction sit at the fast end of that range, because salt film and dust come back to them soonest.
How salty glass should be cleaned
The method differs from ordinary window cleaning in one respect. Salt and grit have to be floated off before anything is rubbed across the glass. Salt crystals and sand are hard, and a dry cloth dragged over them scratches the pane and grinds them into the frame.
- Vacuum the tracks and sills while they are dry. Sand must come out before water goes in, or it turns to paste.
- Wipe the frames, handles and seals with a damp cloth, rinsing the cloth often. Dirty edges put dirt back onto clean glass.
- Wet the glass generously with clean water and a little washing-up liquid on a soft applicator, and give it a minute. This dissolves the salt and loosens the dust.
- Wash it a second time if the first pass comes off grey. On coastal glass it usually does.
- Take the water off with a squeegee, from the top down, wiping the blade after each stroke. Water left to dry on the glass puts minerals straight back.
- Dry the edges and the bottom of the frame with a clean cloth, where water collects.
- Change the water often. A bucket that has washed a salty balcony door is salt water.
- Look at the glass from inside and from outside against the light before the tools are put away.
Work in shade, with soft tools
Clean when the glass is in shade. A sea-facing pane in full sun is hot enough to dry the wash water before the squeegee arrives, and the result is streaks. We avoid working on glass in direct midday sun where we can, for that reason.
Do not reach for a blade or an abrasive pad to speed things up, least of all on tinted film or coated glass. The tools, the technique and the cautions for treated glass are set out in streak-free windows: what professionals use.
When the spots do not rinse off
If white spots remain after a proper wash, they are minerals, not salt. On plain glass, a mild acidic glass cleaner or diluted white vinegar, left on for a few minutes and rinsed away, softens fresh ones. Keep acids off marble and other natural stone on the sill or the balcony floor, where they etch, and rinse the frames afterwards. Never mix a descaler with bleach or with any other product.
If the marks are still there when the glass is clean and dry, the surface itself is etched. Most hard-water spots lift with the right product. Heavy etching does not, and it becomes a question for a glass specialist.
Five minutes a week between proper cleans
A short routine keeps the film from setting and stretches the gap between full cleans. The floor, the drain and the furniture are the other half of a balcony, and the method for those is in how to clean an apartment balcony.
- Wipe the outside face of the balcony door with a well-wrung microfibre cloth, and dry it with a second cloth or a squeegee.
- Wipe the rail and the door handles with a cloth dampened in clean water, then dry them.
- Vacuum the door track.
- After a windy day, wait for the air to clear, then do the same again.
- Never hose the glass and leave it to dry.
- Keep sprinklers and planter drippers pointed away from the glass.
The part of a sea-facing home that can be cleaned from inside
In a tower, a visit covers the inside of all the glass, the balcony glass and the outside of the balcony doors: everything that can be reached from inside or from the balcony floor. The fixed panes on the outside of the building are part of the tower's facade. They need rope access or a cradle, and the building's own contractor handles them.
This matters more by the sea than anywhere else, because the dirtiest face of the glass is the one you cannot reach. Ask the building's management when the next facade round is due, and time your own clean for just after it. The full account of what a team with a step ladder can and cannot reach is in high windows, facades and chandeliers.
Villas on the water
On a waterfront villa the ground-floor glass, the terrace doors and any glass balustrade are all within reach, so both faces can be kept on the monthly rhythm. The same film forms on the walls, and sea air and sprinklers between them leave watermarks on the lower sections. Facade cleaning deals with accessible exterior walls at ground level and low height, and is priced from photos or a free inspection.
Glass, walls and paving are best done in one sequence, so that washing one does not dirty another. The order is set out in the villa outdoor checklist.
What regular glass cleaning costs
Window cleaning uses the hourly price list: AED 55 for 1 hour, AED 65 for 2 hours, AED 30 an hour for 3–4 hours and AED 25 for each hour after that, per cleaner, VAT included, with AED 5 an hour more when we bring the materials. Our service page gives two to three hours for one cleaner as typical for the windows and balcony glass of a two-bedroom apartment. A monthly plan takes 5% off each visit, with no contract and nothing paid ahead. The full list is on the pricing page.
| How you book it | With your products | With our materials |
|---|---|---|
| Two hours, one-off | AED 65 | AED 75 |
| Two hours, monthly plan | AED 61 | AED 71 |
| Three hours, one-off | AED 90 | AED 105 |
| Three hours, monthly plan | AED 85 | AED 99 |
Adding glass to a regular clean
Many customers add window cleaning to every second or third regular visit. For a sea-facing home, once a month suits better. If your weekly clean is three hours, making one visit a month four hours gives the cleaner an hour for the balcony glass, and that visit costs AED 30 more before any plan discount. It is usually the cheapest way to keep coastal glass on a monthly rhythm, because the cleaner is already in the home with the equipment out.
If you book without materials, the cleaner uses what is in your home, so have a squeegee, a bucket and several clean microfibre cloths ready. With materials, we bring them.
Common questions
Does rain clean sea-facing windows?
No. Rain here is rare, falls through dusty air and lands on dusty, salty glass. It wets the film without rinsing it away, and what dries afterwards is a spotted, muddy version of what was there before. Glass usually needs cleaning after rain, not instead of it.
How do I tell salt from ordinary dust?
Dust alone is dry and wipes off as powder. A salt film smears when you wipe it with a dry cloth, feels faintly sticky on a humid morning and dries to a white haze. A pane that looks clean while it is wet and cloudy again once it is dry still has salt or minerals on it.
Will a water-repellent coating keep the glass clean?
Coatings that make water bead and run off are sold for glass, and they can slow the build-up. They do not stop it, they wear, and some tinted films and coated panes should not be treated at all. In a tower the outside face is not yours to coat in any case. Ask the glass supplier or the building's management before buying one, and keep cleaning on the same rhythm until you have seen what difference it makes.
Why is the inside of the glass hazy as well?
Sea salt does not reach it. What does is condensation from the AC, which leaves marks on the inside of the glass and on the frames, together with cooking vapour and fingerprints. It builds far more slowly, which is why the inside face needs cleaning only every two to three months.
What time of day is best?
Whenever the glass is in shade and cool to the touch. Which hours those are depends on the way your balcony faces, so watch it for a day before you book and choose a start time when the sun is off the glass.
The white marks were back the day after cleaning. Was it done badly?
Check two things. If the marks are in the same places and the same shapes as before, they are etched or mineral spots that were wet, and so invisible, when the glass was checked. If they are new and even across the pane, salt has simply arrived again, which one windy night can do. If something on the agreed list was missed, tell us within 24 hours and it is re-cleaned free of charge.
We are away all summer. Should the glass be done before we leave or after we return?
After. Glass cleaned before you leave will carry weeks of film by the time you are back. The exception is the metal. Wipe and dry the rail, the handles and the door track before you go, so that salt is not sitting on them for the whole summer.
Booking glass cleaning for a sea-facing home
Tell us how many windows and glass doors there are, whether there is balcony glass, which way the home faces, and whether any glass is above step-ladder height or can only be reached from outside the building. A photo of the balcony helps. Before the visit, move furniture and plants away from the glass and unlock the sliding doors.
Glass and facade work are listed in our specialist cleaning group. Visits run every day from 8 AM – 8 PM, at the same price on Fridays and public holidays. Choose the hours and book online. Payment is by card once we confirm your booking.
