(Boston, February 11, 2026) — A Massachusetts woman’s decision to pay extra for an undercarriage wash at a car wash has sparked a debate online about whether the service is a worthwhile expense.
A TikTok video posted by Ashley Esper, a content creator from Massachusetts, highlighted the unexpected $4 charge and ignited discussion about vehicle maintenance.
- Ashley Esper was charged $4 for an undercarriage wash at a car wash.
- The debate centers on whether undercarriage washes are necessary, particularly in areas that use road salt.
- Road salt can cause significant rust damage to vehicles, costing billions of dollars annually.
- Opinions vary based on geographic location and climate.
Esper shared a video of her experience on TikTok, expressing uncertainty about the necessity of the extra charge. “Was just convinced to pay an extra $4 to wash the bottom of my car and I’m not sure if that’s really necessary, but the car wash guy was so enthusiastic about it, so if he’s happy, I’m happy,” she wrote in the caption.
The video quickly gained traction, prompting a range of responses in the comments section. Some users supported the car wash employee’s recommendation, emphasizing the importance of cleaning the undercarriage, especially during winter months.
“As a car guy, it is very important in the winter to do the underbody wash. The bottom is usually the first place where rust starts because dirt and salt get trapped under there,” one commenter wrote.
The concern stems from the corrosive effects of road salt, commonly used to melt ice and snow on roadways. According to the AA, road de-icers cause around $3 billion in vehicle rust damage each year.
However, not everyone agreed with the need for the additional service. Some commenters suggested it was unnecessary in warmer climates.
“If you’re in California, ignore his advice,” one user wrote. Another added, “Really matters where and when. Winters where there’s salt on the road, absolutely. Otherwise I do it maybe once every 3-4 washes.”
Massachusetts is among the top 10 snowiest states, according to the World Population Review, suggesting that Esper’s decision to opt for the undercarriage wash may be particularly prudent given the local climate.
Why It Matters
This seemingly minor interaction highlights a broader issue of preventative car maintenance and the potential long-term costs of neglecting certain areas of a vehicle. While a $4 charge may seem insignificant, the potential for rust damage caused by salt exposure can lead to expensive repairs down the line. The debate also underscores how regional factors – specifically climate and road conditions – influence car care practices. For drivers in areas where roads are heavily salted during winter, regular undercarriage washes can be a worthwhile investment in protecting their vehicles from corrosion.
