The short answer
Remove graffiti quickly, with a method matched to both the paint and the surface. Porous masonry, coated metal and glass each need a different approach. Etched graffiti on glass and metal is a restoration job, not a cleaning job.
Method by surface
| Surface | Challenge | Approach |
|---|---|---|
| Brick, stone, concrete | Paint soaks into pores and can leave a shadow | Removers suited to the paint and masonry, low pressure, tested first |
| Painted and coated surfaces | The remover can take the coating with it | Gentle removers, or spot-repainting by the owner |
| Metal | Scratched or etched tags | Metal restoration: sanding, buffing and polishing |
| Glass | Paint, or tags scratched or etched into the glass | Cleaning for paint; glass restoration for etching |
Why speed matters
- Fresh paint comes off more easily than cured paint
- Paint left on porous surfaces soaks in deeper
- Tags left in place tend to attract more
What causes surface damage
- High pressure on masonry or soft finishes
- Harsh solvents on coatings and sealant
- Abrasives on glass
Test a small, inconspicuous area first, and check it before treating the rest.
Preventing repeat tagging
- Remove new tags quickly and consistently
- Improve lighting and sightlines where possible
- Ask about anti-graffiti coatings, which make future removal easier. See what protective coatings prevent and what they don't.
