The short answer
Busy shopfronts, cafés and restaurants on main roads or near the sea usually need the glass cleaned weekly or fortnightly. Quieter shops, offices and upper floors are often fine monthly or quarterly. Book an extra clean after red rain, nearby building work, a village feast or a big event, and before the summer season.
First impressions happen at the glass
Customers see your shopfront before they see anything else. Smeared, salty or dusty glass makes a shop look closed, a restaurant look tired and an office look neglected, however good things are inside. Clean glass also lets people see your displays and lets light into the shop.
Why shopfronts in Malta get dirty fast
Street-level glass in Malta and Gozo takes a lot:
- Traffic. Narrow streets put buses, cars and delivery vans close to the glass. Exhaust film builds up quickly.
- Building work. Construction is everywhere, and cement dust drifts down whole streets.
- Sea salt. On seafronts from Sliema and St Julian’s to Bugibba, Marsaskala and Marsalforn, spray leaves a hazy film. See removing salt from sea-facing windows.
- Red rain and Saharan dust, which leave muddy streaks. See red rain and Saharan dust.
- People. Fingerprints, children’s hands, dogs and bags against the glass, especially around doors.
How often, by type of business
These are typical starting points. Your location and footfall matter as much as your business type.
| Type of premises | Typical schedule |
|---|---|
| Cafés, restaurants, bars on busy streets or seafronts | Weekly |
| Shops on main roads and in town centres | Weekly or fortnightly |
| Quieter shops and side streets | Fortnightly or monthly |
| Offices and showrooms at street level | Fortnightly or monthly |
| Upper-floor offices | Monthly or quarterly |
| Apartment block entrances and stairwells | Monthly or quarterly |
Inside faces can often be done less often than outside, for example every second visit.
When to book an extra clean
After red rain and sandstorms
A red rain episode can undo a fresh clean in hours. Book an extra visit once it has passed, not before.
During or after nearby building work
If there is construction on your street, cement dust will settle on the glass daily. More frequent cleaning helps until the work ends. For paint or cement splashes on the glass itself, see removing paint, cement and silicone from windows.
Around feasts and events
Village festas bring crowds, fireworks residue, confetti and food stalls. A clean before the feast week makes the shop look its best for the extra footfall, and one after clears up the aftermath.
Before the summer season
In tourist areas, a deep clean in late spring, including frames, signs and awnings where reachable, sets you up for the busiest months.
What happens if you leave it
Salt and dust that sit on glass for weeks are harder to remove. Hard water and salt can leave stubborn marks, and grime builds up in frames and door tracks. Regular cleaning keeps each visit quick. See removing hard water stains from glass.
Do not forget the details
A good shopfront clean covers more than the big panes:
- frames, sills and ledges,
- door glass and handles,
- sliding door tracks (see cleaning aluminium sliding door tracks),
- signs and lettering, gently,
- inside faces and display areas.
Simple daily habits
Between professional cleans:
- wipe fingerprints off door glass with a microfibre cloth,
- sweep the entrance so dust is not kicked up onto the glass,
- avoid hosing down the pavement onto the glass with tap water, which leaves spots.
