Whenever gum gets stuck on your car’s carpet, it is usually best if you can remove it right away. It’s easier to clean right away because the gum is still largely intact and you can still pull it off of the carpet without it getting too stuck in the carpet fibers. However, the longer you wait, the more likely it will get stepped on, further embedding it into the fibers of the carpet. This results in the gum being harder to remove later on.
