Removing Paint, Graffiti & Other Difficult Stains from Glass

man removing graffiti from glass window

When your outdoor glass windows become untidy from dirt and dust, they can usually be cleaned with ease. However, retailers we work with on a regular basis attest that there are many more challenging stains they are faced with removing from their shopfront windows.

Care must be taken to avoid causing abrasion to glass surfaces. Dirty windows are bad for business, but scratches are even worse! An easy mistake to make is to clean windows with the same mop or sponges you use to clean other surfaces such as the floor. The cleaning devices can contain small particles of rock or other rubbish which can easily go unnoticed and scratch the paint. Avoid the use of scourer pads, as they cause tiny scratches, which can provide a place for dirt to sit. Scourers will also scratch through any tinting or protective coating which may be present. Jewellery such as rings and watches can cause scratches, so remove these or at least cover them with long, thick gloves before performing any cleaning task.

Debris can also form on and around your windows, such as steel shavings from construction, rust particles from window frames, concrete dust from walls and pavement. Such debris can damage your windows by scratching the surface or when the chemicals they emit come into contact with the glass. It’s important to inspect the glass and surrounding areas before commencing any cleaning. Ideally, we recommend covering windows when performing cleaning or maintenance in surrounding areas, such as high pressure cleaning, welding, sawing, sanding or painting

Glass stain remover products are available from hardware stores which claim to remove a long list of stubborn stains. Unfortunately in stain removal there isn’t one solution for all stains. Dirt requires a different solution to rust stains, which require a different solution to paint. And if your glass is scratched, tinted or has a protective coating, these factors will also effect the correct choice of cleaning solution.

Certain stain types cannot be removed with regular cleaning methods and require specialists who have the skills and experience to remove the stain without causing abrasion. These stain types include graffiti, paint spills, hard water and oxidisation.

A trick many have attempted when removing paint from glass is to use the sharp, thin blade of a razor or Stanley knife to slide underneath the paint and scrape it off. While this may remove the paint, it creates a larger problem by digging scratches into the glass.

In the following video Greg Luckett, our Gold Coast graffiti removal specialist, removes paint from the window of a local retailer, caused by graffiti vandalism. Graffiti is one of the most difficult stains for retail managers to rectify. After their cleaning staff have scrubbed and scrubbed with nothing to show for their efforts, we receive calls from managers who need to have graffiti removed urgently. Not only does graffiti often block the ability of those passing by to view the shops products, it creates a negative first impression, deterring potential customers from entering.

Our technicians carry 26 different stain removal formulations, enabling selection of the right solution for the specific stain and surface type. The right selection of stain removal formulation enabled Greg to gently remove the graffiti by hand, without resorting to abrasive measures. As you can see in the video, the window is restored to its original condition.

Areas that frequently receive harsh stains such as graffiti can benefit from a glass protection film which enable a fast response to stains and vandalism, allowing most stains to be wiped off with ease.

The Graffiti Eaters work with retailers such as Woolworths, Kmart and 7/11 to restore their windows and glass surfaces from graffiti, paint and other harsh stains, and implement protective coatings to maintain their assets for years to come.
