Generally, most graffiti tags on windows and glass can be easily wiped away using Safewipes or Sensitive Surface Graffiti Remover in the conventional way.
Larger spray paint graffiti on windows can be removed using Bare Brick Stone & Masonry Graffiti Remover.
When dissolving a lot of spray paint on windows brush or broom it on in sections and agitate as you apply to fully dissolve the graffiti before rinsing it off a few minutes later with your pressure washer. Stand back and use a green 25° tip taking care not to use too much pressure.
Make sure you aren’t allowing the remover to drip directly onto more sensitive aluminum or anodized window mullions which could potentially discolor them if exposed to the remover for too long.
Sometimes masking frames off is best, or at least wetting them down first with your pressure washer is best.

Glass is impervious to any of our removers and cannot be damaged by them. For heavier paint overs and baked-on spray paints Transgel left on for longer may be the best option.
When graffiti occurs on the interior of buildings or on shop fronts sometimes a large razor blade scraper can be a good option.
How to remove scratches & acid-etched graffiti on glass
Because there has been an irreversible chemical reaction to the glass, there isn’t a cleaner that will remove these tags. However, most can be removed ‘mechanically’ through buffing and polishing. Specialized equipment is available for this job.
Glass windows and signage can be protected with optically clear laminates and films. In the event of graffiti, these are peeled away and replaced.

3 Golden Rules
1) If graffiti is not coming off easily, you're doing wrong! You may require a change of tact or use of another product.
2) If you can't remove a little bit of graffiti, then you're not going to remove a lot. TEST FIRST before applying product to an entire job. This way you can determine if you’re on the right track before embarking on full scale removals.
3) If you're working hard, you're doing it wrong. Forget the scrubbing, blasting and any other abrasive measures. Put simply, either your products are working or they’re not. Any problems can be taken care of with the right technique.
