Graffiti Removal from Aluminium and Steel
Metal surfaces appear across a huge range of applications — building facades, street furniture, fencing, gates, roller doors, and equipment — and while they’re generally durable, they carry specific risks when it comes to graffiti removal.
The two biggest are corrosion and staining. Cleaning solutions that aren’t properly neutralised after the job can cause rust and corrosion to develop on steel surfaces over time. And on galvanised steel and aluminium in particular, the wrong cleaning solution can permanently stain or discolour the finish — damage that is difficult or impossible to reverse.
Getting the chemistry right — and completing the full process correctly — is what separates a clean result from a costly one.
How We Remove Graffiti from Aluminium and Steel
All graffiti removal from aluminium and steel surfaces is carried out by hand — pressure washing is not used on these surfaces. Hand application gives our technicians precise control over both the cleaning solution and the removal process.
How we treat it:
1. Surface assessment
On arrival, our technician assesses the metal type, surface finish, and graffiti substance. This determines the correct cleaning solution and approach for that specific combination — because what works safely on brushed stainless steel may not be appropriate for galvanised steel or anodised aluminium.
2. Specialist cleaning solution
A carefully selected graffiti cleaning solution suited to the metal surface is applied by hand. Solution selection is critical — particularly on galvanised and aluminium surfaces — to ensure effective graffiti removal without staining, discolouration, or surface damage.
3. Careful hand removal
The graffiti is removed carefully by hand using appropriate tools and technique. Abrasive materials are avoided to protect the surface finish.
4. Neutralising solution
Once the graffiti has been removed, a neutralising solution is applied to the surface. This step is essential — it stops any residual cleaning solution activity and protects the metal from corrosion that could otherwise develop over time.
Metal Surfaces and Finishes We Treat
We remove graffiti from a wide range of aluminium and steel surfaces and applications:
- Mild steel
- Stainless steel
- Galvanised steel
- Aluminium panels and cladding
- Powder coated metal surfaces
- Roller doors and shutters
- Security gates and bollards
- Street furniture and infrastructure
- Building facades and canopies
- Industrial equipment and structures
What to Expect
- Hand application — precise control throughout the removal process
- Surface and finish assessment on arrival — the right cleaning solution is always matched to the specific metal and finish
- Neutralising treatment applied after every job — protecting the metal from corrosion caused by residual cleaning cleaning solutions
- Careful product selection for galvanised and aluminium surfaces to prevent staining or discolouration
- No abrasive materials — surface finish integrity is protected throughout
- $20 million public liability insurance covers every job
– Safe elevated access available where required for high-mounted metal surfaces and structures
Act Quickly for the Best Result
Fresh graffiti that hasn’t fully cured is significantly easier to remove from metal surfaces — and requires less aggressive treatment, reducing the risk to the surface finish. The longer graffiti is left, the more firmly it bonds to the metal, and the more intensive the treatment required to remove it.
On uncoated or bare metal surfaces especially, prompt removal also reduces the risk of the graffiti substance itself contributing to surface staining or corrosion over time.
Protect Your Metal Surfaces from Future Graffiti
An anti-graffiti coating applied after removal creates a protective barrier between the metal surface and any future graffiti — making subsequent incidents quicker, easier, and safer to remove, and reducing the risk of surface damage during the cleaning process.
