Your display window does sales work long before anyone steps inside. Before a customer reads a price tag or notices the cake under the counter, they register whether the glass looks cared for. A bright pane suggests a shop that pays attention; a smeared one suggests the opposite, fairly or not. A professional clean deals with the reach, the heights, the hardened film and the frames. The rest is routine, and it takes less time than most owners assume. What follows is a checklist organised by how often each job needs doing, so the glass stays presentable between visits.

Daily: The Two-Minute Walk-Around

Give yourself two minutes before you unlock the door. Stand outside first — the street-side view is the one that counts, and problems look different from the pavement than they do from behind the counter. Morning light is useful here: raking sunlight shows up smears, dust and the shadow of last night's fingerprints.

Then step inside and look out. Interior marks are easy to ignore because you stop seeing them; visitors do not. Concentrate on the band between waist and eye height, where hands, bags and children's faces land.

• Check the glass from both sides in daylight, starting on the pavement.
• Wipe the door handle, push plate and the glass immediately around them — the most-touched square metre of the whole shopfront.
• Spot-clean fingerprints and nose marks at display height with a damp microfiber, then buff dry with a second cloth.
• Look along the bottom 30 cm of the glass, where shoes, bags and dogs brush past. That strip dulls first.
• Check the sill and inner ledge for dust, old price cards and debris from yesterday's display change.
• Note anything that needs more than a spot-clean and leave it for the weekly pass.

Keep a folded microfiber and a small spray bottle within reach of the till. A routine only survives if it costs no effort to start.

Weekly: The Full Pass, Inside and Out

Once a week, set aside twenty to thirty minutes, ideally before opening or after the last customer has gone. Work top to bottom and outside to inside, so you aren't carrying dirt back through a clean doorway.

Exterior glass and frames

Traffic film and dust build up in a thin, even layer that spot-cleaning cannot fix. Wipe the frames and mullions with mild soapy water, rinse with clean water and dry the metal — standing water leaves mineral marks on dark anodised finishes. Pay attention to the corners where glass meets frame; that is where black grime gathers, and where it streaks downward after the first rain.

Interior glass, especially in cafés

Interior glass in a café or bakery collects a fine haze long before it looks dirty: steam from the machine, oil from the kitchen, dust settling into both. Use a degreasing microfiber and a mild detergent solution, then finish with a plain-water pass and a dry cloth. Skip it and the window will look grey by mid-afternoon even when the outside is spotless.

Signage, decals and door edges

Check that vinyl opening hours, card-reader stickers and window graphics are still flat, and clean around their edges where grime collects. Work around vinyl rather than over it where you can, and never scrape near it with a blade. Then open and close the door with a cloth in hand — the leading edge and the hinge side pick up grime quickly.

Monthly: The Parts You Don't Notice Until They Fail

Monthly work is less about shine and more about keeping the glass and its fittings in good condition.

• Vacuum the sliding tracks and door runners with a crevice tool before wiping them. Grit left in a track grinds the rollers every time the door moves.
• Check that drainage slots and weep holes in the frame are clear, so water can escape instead of sitting against the seal.
• Inspect sealant and putty, particularly on older shopfronts. Cracks and gaps let water behind the glass, which later shows up as a stain you cannot clean off.
• Dust the spotlights, diffusers and the soffit above the window. Dust there runs down onto the glass with condensation.
• Clear leaves and debris from any awning or canopy above the display — after rain they send brown streaks down a clean pane.
• Look at inside corners for condensation and any sign of mould, and improve ventilation if you find it.
• Note high panels, transoms or awkward corners you cannot reach safely, and hand them to your window cleaner on the next visit.

Two of those jobs take five minutes and can save a repair bill: the tracks and the weep holes.

The Kit Worth Keeping Under the Counter

You don't need a professional's van. You do need tools that don't make things worse.

• Two or three microfiber cloths — one damp, one dry, one for frames. Wash them without fabric softener, which leaves a film on glass.
• A small spray bottle of water with a drop or two of mild washing-up liquid.
• A squeegee sized to the pane — a narrow blade is easier to control on slim shopfront panels than a wide one.
• A soft detail brush for tracks, gaskets and corners.
• A plastic scraper for tape residue and sticker gum, held flat to the glass and kept well away from vinyl.

Skip ammonia-based cleaners on tinted film or applied graphics, and skip abrasive pads altogether. They leave a permanent haze that no cleaner will lift.

Weather, Seasons and Timing

Timing matters as much as technique. Cleaning glass in direct sun on a warm day is a losing battle: the solution dries before you can squeegee it, and it dries in streaks. Work in shade, early in the morning, or start on the shaded side of the street. In cold weather, dry the frames properly afterwards and keep water away from gaskets, where trapped moisture causes problems over a winter.

Each season brings its own grit. Spring pollen settles as a yellow film that reappears within days. Summer adds insect marks and dry dust. Autumn leaves stain the glass brown wherever they sit against it, and winter road salt sprays the street-facing panes and dries into a white crust that scratches if you wipe it dry. Adjust frequency rather than effort: a busy road in winter may need the exterior pass twice a week.

Put It on the Calendar, Not on the List

A checklist only works if it has a slot. Write the two-minute walk into the opening routine of whoever unlocks the door, so it belongs to a person rather than to everyone in general. Pair the weekly pass with another job nobody enjoys — cashing up, restocking the chiller — and it becomes habit instead of an intention. The monthly inspection fits neatly with a fire-safety or maintenance check.

Be honest about the limits, too. Anything above head height on a busy pavement, anything requiring a ladder against a shopfront, and anything over a doorway needs proper access equipment and someone trained to use it. That belongs to a professional clean, booked regularly — monthly or quarterly, depending on how exposed your street is. If you are unsure about a seal, a crack in the frame or water appearing behind the glass, ask a professional to look rather than working around it.

Between those visits, the routine above is enough. Two minutes a day, half an hour a week, an hour a month, and the window does its job: it makes the shop look like somewhere worth walking into.
