Metal Cleaning & Graffiti Removal
Shutters, railings, bollards, balustrades and street furniture. Non-porous, so graffiti usually comes off cleanly — the skill is removing it without stripping the powder coating or galvanising underneath.
Metal is the most frequently tagged surface in any town centre, and it's easy to see why: shutters, cabinets, bins and signage are flat, blank, at street level and unowned-looking. They're the default canvas.
The advantage is that metal is non-porous. Nothing soaks in, so removal is a question of taking a coating off a coating without touching the one you want to keep. Get that right and the result is genuinely as-new, with no ghost — which is not something we can promise on brick or stone.
It's the finish that matters, not the metal
Almost no metal in the built environment is bare. What we're actually cleaning is the finish on it, and that's what determines the method.
Powder coating — the standard on shutters, railings, bollards and street furniture. Tough and generally solvent-resistant, but strong removers left too long will soften it, and once it's dulled the patch shows.
Galvanising — a sacrificial zinc layer on steel fencing, columns and posts. Remove it and the steel beneath starts corroding, so aggressive abrasion is never appropriate.
Stainless steel — common on modern street furniture and balustrades, often with a directional brushed grain. It scratches, and a scratch across the grain is permanent and highly visible.
Anodised aluminium — on shopfronts, window frames and cladding trims. The anodised layer is thin and attacked by both acids and strong alkalis.
The most common irreversible damage we see on metal isn't from graffiti — it's from someone attacking a tag with a wire brush or an abrasive pad. On brushed stainless or a powder-coated shutter that damage is permanent, and it's far more visible than the tag was.
How we remove graffiti from metal
Always mildest first. We start with a gel remover appropriate to the paint, applied to a small area and given a short dwell, then wiped and checked. If it lifts the aerosol without touching the finish, we work across the rest at the same settings. If it doesn't, we step up one grade and test again.
Short dwell times are the key discipline. Most damage to powder coating comes from leaving a strong remover on while going to do something else — the product doesn't stop when the graffiti is gone. Steam then rinses the residue and finishes the surface without adding more chemistry.
For stickers and fly-posting the approach is different again: heat softens the adhesive so the material peels rather than shreds, then an adhesive remover takes the residue. Scraping cold, which is what usually happens before we're called, tends to leave a torn mess and scratches.
- Identify the finish — powder coat, galvanised, stainless, anodised or painted
- Test the mildest viable product in a discreet spot with a short dwell
- Work in small sections, never leaving product on beyond its working time
- Neutralise and rinse, usually with steam, so no residue is left to keep working
- Protective coating on repeat-target shutters and furniture where it makes sense
Shutters, railings or street furniture been tagged?
We remove graffiti and stickers from metal across Greater Manchester without stripping the finish underneath — and we can usually get to it fast.
Shutters and shopfronts
Roller shutters are the single most tagged item in most town centres. They're large, flat and only exposed when the business is closed, which is exactly when a tagger is working.
Corrugated shutter profiles make removal fiddlier than it looks — paint collects in the flutes and a flat pad simply skims the ridges. It needs working into the profile section by section, which is slower but the difference between a clean shutter and a smeared one.
For businesses being hit repeatedly, an anti-graffiti coating on a shutter is one of the clearest value cases we see. Removal drops to a hot-water wipe-down that takes minutes, which means a tag can be gone before the shop opens rather than sitting there for a week waiting for a contractor. Our shutter and shopfront cleaning page has more.
Rust and when cleaning isn't the answer
Where a coating has already failed and the metal beneath is corroding, cleaning has limits worth stating plainly. We can remove the graffiti, wash off the loose material and make the item look considerably better, but we can't restore a finish that isn't there.
Rusting railings, bollards with the galvanising worn off at the base, or a shutter with corrosion along the bottom slat all need repainting or replacing rather than cleaning. We'll photograph and flag those items in the job report so they can go on the maintenance list, but we won't take money for cleaning something that needs a decorator.
It's also worth knowing that rust bleeding from a metal fixing onto masonry is a separate problem — see rust staining — and treating the stain without dealing with the corroding metal only buys a year or two.
Metal At A Glance
Where we come across it
- Roller shutters and shopfronts across town centres and retail parades
- Railings, balustrades, gates and estate fencing
- Bollards, benches, bins, cycle stands and street furniture
- Signage, lighting columns, cabinets and utility housings
What damages it
The mistakes we're most often called in to fix.
- Solvent removers soften and dull powder-coated and painted finishes
- Abrasives scratch stainless and anodised surfaces permanently
- Stripping galvanising exposes the steel and starts corrosion
- Acidic products cause staining and pitting on aluminium

Frequently Asked Questions
Will graffiti removal damage the paint on my shutters?
It shouldn't, on a sound powder-coated or painted finish. We test the mildest effective product first and keep dwell times short, because damage almost always comes from leaving a strong remover on too long rather than from the product itself. On old or unknown coatings there's a genuine risk the remover takes both, and we'll tell you that after the test patch rather than after the whole shutter.
Can you remove stickers and fly-posting from metal?
Yes, and usually completely. We use heat to soften the adhesive so the material lifts rather than shreds, then an adhesive remover for the residue. Cold scraping — which is what's usually been tried before we arrive — tends to leave torn paper and scratches that are harder to deal with than the original sticker.
How quickly can you get to tagged shutters?
We prioritise shopfronts and anything offensive, and for businesses across Greater Manchester we can often attend within a day or two. If your shutters are a repeat target, an anti-graffiti coating means the next removal takes minutes rather than needing a specialist visit at all.
Can you clean rusty railings?
We can clean them, but cleaning won't fix them. Once the coating has failed and the steel is corroding, the item needs preparing and repainting — cleaning alone will make it look better briefly and then the rust returns. We'll photograph anything in that condition and flag it so it can go on the maintenance list.
