(And Why Regular Car Washes Matter)

Winter weather keeps our roads safer—but it can be rough on your car. Road salt is one of the biggest culprits behind long-term vehicle damage, especially when it comes to rust. Understanding how salt affects your car and why regular washing matters can help you protect your investment and keep your vehicle looking and running its best.

How Road Salt Damages Your Car

Road salt works by lowering the freezing point of water, preventing ice from forming on roads. Unfortunately, that same salt sticks to your vehicle and accelerates corrosion.

When salt mixes with moisture, it creates a corrosive solution that can eat away at metal surfaces. Over time, this leads to:

• Rust on the undercarriage
• Corrosion on brake lines and suspension components
• Damage to wheel wells, doors, and body panels

The undercarriage is especially vulnerable because salt and slush get trapped underneath your vehicle and are often overlooked.

Why Winter Car Washes Are Essential

Many people assume washing their car in winter is unnecessary—but it’s actually one of the most important times to do it.

Regular car washes help:

• Remove salt buildup before it causes corrosion
• Protect exposed metal components
• Extend the life of your vehicle’s frame and parts
• Keep your car looking clean despite harsh conditions

A wash that includes an undercarriage rinse is especially effective at flushing away salt and grime from hard-to-reach areas.

Don’t Wait Until Spring

Waiting until winter is over allows salt to sit on your vehicle for months, increasing the risk of rust. Washing your car regularly throughout the winter—even during colder weeks—can significantly reduce long-term damage.
