General rules
- Use mild soapy water and a soft cloth or sponge.
- Rinse with clean water and dry with a soft cloth to avoid marks.
- Avoid abrasive pads, scouring powders and harsh solvents.
- Avoid high-pressure jets close to edges of vinyl and laminate.
- Work safely: use proper access equipment for high signs, or ask a professional.
By sign type
ACP and chromadek boards
Wash gently to remove dust and grime. Check fixings and edges occasionally, particularly on chromadek, where cut steel edges can be vulnerable to moisture.
Perspex
Use a very soft cloth; perspex scratches easily. Avoid paper towels, abrasive cleaners and solvent-based glass cleaners.
Vinyl graphics and decals
Clean gently and avoid picking at edges. If a corner starts to lift, deal with it early before dirt gets underneath.
Vehicle wraps and decals
Hand wash where possible, avoid high-pressure jets on edges, and do not use solvents or abrasive polishes. Park in shade when you can.
Banners and flags
Wipe PVC banners with mild soapy water. Store banners rolled, print side out, clean and dry. Take flags and banners down in strong wind.
Light boxes
Keep the face clean so light shines through evenly, and have any lighting issues attended to. Switch off power before any cleaning near electrical parts.
Safety signs
Keep them clean and visible, and replace any that are faded or damaged. Photoluminescent signs need light to charge, so keep them unobstructed.
A simple routine
- Monthly: a quick look at your main signs for dirt, damage or lifting vinyl.
- Quarterly: a gentle wash of accessible signs and window graphics.
- After storms: check fixings, banners, flags and any freestanding signs.
- Yearly: review whether promotional graphics, contact details and safety signs are still current.
When to refresh or replace
Faded colours, cracked boards, peeling vinyl, outdated phone numbers or branding all send the wrong message. Replacing a face or a vinyl layer is often cheaper than a whole new sign.
