How should pylons and signs be cleaned, and how often?

The short answer: there is no single cleaning interval that fits every sign. Frequency should be planned around location, weather and the brand's visual standard. Cleaning should use a method suited to the sign's surface, and maintenance topics such as fixing, repairs and electrical work should be handled separately from cleaning. Below you will find the types of signage, the factors that drive frequency, the difference between cleaning and maintenance, and how to hold the standard across many branches.

What types of signage are there?

Before planning cleaning, build a signage inventory for the network. Each type can sit at a different height, be made of different materials and have different access conditions, which directly affects team, equipment and time planning.

For each site, record the sign type, its approximate position, how it is accessed and whether it is illuminated. This record is the basis of both the cleaning plan and later audits.

• Pylons and price boards: tall structures at fuel stations carrying price and brand information visible from the road.
• Illuminated and box letters: brand lettering on the façades of shops, restaurants and bank branches.
• Vinyl and shopfront graphics: corporate and campaign graphics applied to glass.
• Wayfinding: signs for entry, exit, car park and service areas.
• Posters, stands and digital screens: visual elements carrying campaign messages that change more often.

Surface-appropriate cleaning

The core principle of sign cleaning is a method suited to the surface. Composite, metal, painted surfaces, glass, acrylic and vinyl are not cleaned the same way; the wrong method can dull a surface, lift vinyl or fade colours. Method, equipment and chemical standards should therefore be set in advance for each sign type, and every team should apply the same standard. The sign manufacturer's recommendations and brand standards should guide product choice.

Illuminated signs need care. Electrical components, connection points and cables must not be touched during cleaning. Electrical issues such as unlit letters, faulty lighting or damaged cables are left to authorised specialists; the cleaning team photographs and reports them.

For pylons and façade signs that require work at height, a safe access plan should be in place before work starts. Equipment, cordoning off the work area and safe traffic management should be planned in line with the relevant regulations and brand standards.

• Define a method and equipment standard for each sign type.
• Keep away from electrical components on illuminated signs; report faults, do not fix them.
• Plan work at height in advance and secure the work area.
• Take before and after photos from the same angle.

Cleaning or maintenance?

Signage creates two different needs on site, and mixing them up blurs both the plan and the budget. Cleaning removes dust, exhaust marks, dirt and stains to restore visibility. At BİGEL this is done with the Signage & Totem Clean module under CLEAN.

Maintenance concerns the sign's physical condition: securing loose fixings, minor repairs and correcting damaged parts. At BİGEL this runs under the Sign Care module of CARE. Any maintenance need spotted during cleaning is photographed and turned into a separate work order, so the cleaning team does not work outside its scope and the finding is not lost.

What drives cleaning frequency?

Setting frequency by factors rather than a single calendar uses resources well and protects visibility. Even within one network, sites can be visited at different intervals.

In practice, grouping sites helps: roadside locations with heavy traffic go on a tighter schedule, sheltered ones on a lighter one. A periodic programme can be monthly, bi-monthly, quarterly or seasonal, with emergency visits added for sudden soiling or before an audit.

• Roadside dust and exhaust: pylons and signs facing heavy traffic get dirty faster.
• Season: winter grime, mud and leaf fall; some regions need extra seasonal visits.
• Campaign changes: signs are expected to be clean before and after new campaign material goes up.
• Audit findings: sites where sign cleanliness failed an audit are prioritised.
• Brand standard: some brands require more frequent cleaning for visibility.

Holding the signage standard across many branches

Cleaning a sign at one site is simple. Across hundreds of branches, the real challenge is getting the same result everywhere and being able to see it from head office. Working with different suppliers in different cities means different quality, different reporting and results you cannot compare.

The way to hold the standard is to share both the execution and the evidence. A network-wide check after a signage change or a new campaign also confirms that the rollout is complete.

• Manage the whole network with one provider and one point of contact.
• A shared checklist: cleanliness, legibility, lighting and damage.
• Standard photo angles: record each sign from the same angle on every visit.
• Records: date, site, team, before and after photos, maintenance needs identified.
• A project audit after signage changes or campaigns for a bulk check.

Sign cleaning by sector

The scope of sign cleaning varies by sector. At fuel stations the pylon and price board come first; in chain retail it is the façade sign and shopfront; at restaurants the façade, signage and drive-thru area; at bank branches the façade sign and the ATM surroundings. See the sector pages for scope.
