What is the recommended method for removing inspection stickers from vehicles with plastic inner liners?

Using a stiff plastic scraper is the recommended method for removing inspection stickers from vehicles with plastic inner liners. This approach minimizes the risk of damaging the underlying plastic surface while effectively removing the sticker. The flexibility and durability of a stiff plastic scraper allow it to glide under the sticker without the sharp edges that can scratch or gouge the plastic material.

Choosing a metal scraper or a razor blade poses significant risks. Metal scrapers can easily create scratches, and the blades can cut into the plastic liner, compromising the integrity of the structure. Leaving the stickers intact may not be a viable option, especially if they need to be replaced or when the vehicle requires a new inspection, which can lead to complications for the vehicle owner. Thus, using a stiff plastic scraper is the safest and most effective method for this task.
