Can stickers be applied to a dirty surface?

Stickers must be applied to a clean surface to ensure proper adhesion and longevity. When a sticker is placed on a dirty surface, contaminants such as dust, grease, or moisture can interfere with the adhesive properties, leading to poor bonding. This results in a higher likelihood of the sticker peeling or falling off over time. For optimal results, it is essential to clean the area where the sticker will be applied, allowing the adhesive to make full contact with the material underneath. This practice is crucial in applications where durability and appearance are important, such as in vehicle inspections, where stickers are often used to indicate passing status or compliance.
