No, you should not vape in a rental car. Virtually all major rental companies explicitly prohibit smoking and vaping in their vehicles. Violating this can result in hefty fines, often called cleaning fees, which typically range from $250 to over $500. These charges are strictly enforced because the odor from vapor and nicotine residue is difficult to eliminate and diminishes the car's value for future customers. The policy is clearly stated in your rental agreement, and companies can charge you based on evidence like odor or visible residue reported by staff or subsequent renters.
The prohibition isn't just about odor; it's also about maintenance. Vape residue can coat interior surfaces like windows and upholstery, requiring deep cleaning. More importantly, some car sensors can be sensitive to the particulates in vapor, potentially triggering false alerts. While the risk is low, it's an additional reason for the ban.
If you are a vaper, your best course of action is to treat the rental car as a non-smoking/vaping zone. Pull over safely in a parking lot and step completely outside the vehicle to vape. This simple action will save you from a significant and unavoidable charge upon returning the car. The policy is non-negotiable, so adherence is the only way to avoid financial penalties.

Check your contract. It's right there in the fine print—no smoking, which always includes vaping. They will charge you a cleaning fee if they smell it or find any residue. I learned the hard way; it was a $300 mistake. Just step outside the car. It’s not worth the argument or the cost.

As a frequent renter for business, I always treat the car like a hotel room: no vaping inside. The chemicals in the vapor leave a film on the windows that's tough to clean and a faint, sweet odor in the fabrics. The rental agencies have specialized equipment to detect it. It's a strict for a reason, primarily to ensure the next customer gets a clean car.

Think about it from the rental company's perspective. Their goal is to rent the same car to as many people as possible, back-to-back. A car that smells like vape juice is going to get immediate complaints and might be taken out of service for a costly cleanup. That's why the penalty is so high—it's meant to be a serious deterrent. It’s purely a business decision to protect their asset.

Even if you think cracking a window is enough, the residue from vaping still settles on surfaces. That film on the inside of the windshield is a dead giveaway. The fees aren't just punitive; they cover a legitimate deep-cleaning process. For your own wallet's sake, make a quick stop. It’s easier and cheaper than trying to argue the charge later, which you will almost certainly lose.
