Maintenance & Cleaning: How to Care for Your Signage

Why Proper Maintenance Matters

Signage is exposed to a wide range of conditions — UV light, moisture, road grime, airborne pollutants, contaminants, and physical contact. Even indoor signs can collect dust or fingerprints over time.

Good maintenance:

• extends the life of vinyl and printed graphics

• preserves colour vibrancy

• prevents premature wear and fading

• protects laminate films from abrasion

• reduces the need for repairs or replacements

• keeps your brand looking clean and professional

High-quality signage lasts even longer when cared for properly.

General Cleaning Guidelines for Most Signage

Regardless of material or location, most signs follow the same basic care instructions.

What to Use

• A soft microfiber or lint-free cloth

• Mild dish soap diluted with warm water

• A soft spray bottle or bucket

• A non-abrasive sponge

• Clean water for rinsing

What to Avoid

• Abrasive scrubbers or Scotch-Brite pads

• Harsh solvents like acetone or thinners

• Citrus degreasers

• High-pressure water blasting

• Products containing ammonia or silicone

• Abrasive powders or cleaners

• Petrol-based cleaners

These can damage laminate, cloud acrylic, scratch printed surfaces, or weaken vinyl edges.

Cleaning Frequency

• Exterior signage: every 3–6 months

• Vehicle graphics: every 2–4 weeks

• Indoor signage: every 3–6 months

• High-touch signage (receptions, counters): as needed

Regular light cleaning prevents dirt from becoming abrasive.

Cleaning Methods by Sign Type

Different materials require different care methods. Here’s how to clean each type safely.

ACM Panel Signs

ACM panels are durable and easy to clean, but the printed laminate surface must be treated gently.

Best method:

• Rinse with clean water

• Use mild soap and a soft cloth

• Avoid scrubbing edges

• Rinse thoroughly and dry with a microfiber cloth

Avoid:

• High-pressure washing

• Abrasive cleaners

• Harsh degreasers

More information on ACM performance is available in our ACM Panel Signs.

Printed & Laminated Vinyl Graphics

Used on ACM, glass, vehicles, windows, and walls.

Best method:

• Soap, water, and a soft cloth

• Rinse to avoid streaks

• Wipe edges gently

Avoid:

• Pressure washers aimed at edges

• Harsh car wash chemicals

• Bug/tar removers containing petroleum solvents

Lamination protects the print but still requires gentle care.

3D Acrylic Letters & Acrylic Panels

Acrylic is strong but prone to scratching.

Best method:

• Use a soft, damp microfiber cloth

• Mild soapy water is ideal

• Pat dry rather than dragging a dry cloth

Avoid:

• Glass cleaner

• Alcohol-based sprays

• Abrasive cloths

• Paper towels

• Cleaners containing ammonia

See more examples under 3D Acrylic Letters.

Illuminated Signs (Lightboxes & Halo-Lit Letters)

These signs contain electrical components and sealed housings.

Best method:

• Wipe the exterior faces with mild soap and water

• Avoid spraying water into vents or seams

• Use a soft cloth only

Avoid:

• High-pressure water

• Opening housings

• Harsh solvents on acrylic faces

See more in Illuminated Signs.

Window Graphics

Window graphics are durable but edges are vulnerable to abrasion and chemicals.

Best method:

• Alcohol-based glass cleaner (no silicone)

• Soft cloth

• Avoid vigorous scrubbing of edges

Avoid:

• Ammonia cleaners

• Razor blades for scraping

• Over-wetting edges

Wall Graphics & Interior Branding

These graphics have different needs depending on paint finish and texture.

Best method:

• Soft dry dusting cloth

• Light wipe with damp microfiber for marks

• Avoid over-saturating edges

Avoid:

• Magic erasers

• Strong detergents

• Excessive water

• Scrubbing textured walls

See more under Interior Branding.

Vehicle Graphics

Vehicles encounter more contaminants than any other sign type.

Best method:

• Hand washing with mild soap

• Soft sponge or cloth

• Rinse thoroughly

• Dry with microfiber cloth

Avoid:

• Automatic car washes with brushes

• High-pressure jets close to edges

• Diesel-based cleaners

• Polishes or waxes on vinyl

• Strong degreasers

Vehicle graphics last significantly longer with proper care.

Environmental Care Tips

Coastal Environments

Salt deposits accelerate wear.

• Rinse every 2–4 weeks

• Use gentle soap solution

• Dry thoroughly to avoid salt spotting

High-Traffic Areas

Reception signage and interior panels may collect fingerprints, dust, and airborne oils.

Vehicle Graphics in Industrial Areas

Exposure to diesel soot, industrial fallout, or chemical mist increases the need for cleaning to prevent staining or etching.

Common Cleaning Mistakes to Avoid

High-pressure washing

Forces water under vinyl edges, causing lifting and premature failure.

Abrasive pads or magic erasers

Scratch laminate, cloud acrylic, and damage matte finishes.

Harsh solvents

Thinners, acetone, tar removers, and petrol-based products soften or dissolve adhesive and print layers.

Ammonia-based cleaners

Deteriorate laminate and leave streaks.

Scraping with razors or hard tools

Gouges or tears vinyl easily.

Signs of Wear & When to Replace

Even well-maintained signage eventually ages. Watch for:

• fading or UV bleaching

• cracks in vinyl

• shrinking edges

• bubbling

• corrosion around fixings

• peeling laminate

• water ingress in illuminated signs

• chalking on aged ACM coatings

Weather-related ageing is also explained in our Weather & UV Exposure guide.

When to Book Maintenance or Repairs

Consider professional attention when:

• illuminated signs dim or flicker

• acrylic panels show deep scratches

• vinyl graphics lift at edges

• vehicle graphics begin cracking

• hardware becomes loose

• corrosion appears on fixings

Ignoring early damage often shortens total lifespan.

Summary: Gentle Cleaning Keeps Signs Looking New

Signage lasts longest when it’s cleaned regularly, treated gently, and protected from harsh chemicals. Whether it’s vinyl graphics, acrylic letters, ACM panels, or vehicle branding, proper maintenance ensures your investment lasts as long as possible — and keeps your brand looking sharp.
