Have you ever noticed someone leaving their windshield wipers standing upright when they park? It may look unusual, but some drivers do this when extreme heat or freezing temperatures are expected. The idea is to reduce the blade’s prolonged contact with the windshield and help prevent certain weather-related problems.

During hot weather, a vehicle parked in direct sunlight can become extremely hot. Constant exposure to heat and sunlight can contribute to the rubber on wiper blades becoming dry, hard, or cracked over time. Lifting the blades away from the glass may reduce their direct contact with a hot windshield, although it will not prevent normal wear and aging.

Freezing weather presents a different challenge. Snow, sleet, or freezing rain can cause wiper blades to become stuck firmly to the windshield. Turning on frozen wipers can damage the rubber or place unnecessary strain on the wiper motor and mechanism. Raising the blades before a freezing night can help prevent them from sticking, but drivers should check their vehicle’s owner’s manual because some models require the wipers to be placed in a specific position.

Regardless of the weather, windshield wipers eventually need to be replaced. Streaking, squeaking, chattering, cracked rubber, or areas of glass that remain uncleared are common signs that the blades are wearing out. Keeping the windshield clean can also improve performance. During winter, heavy snow and ice should be removed manually with an appropriate scraper rather than relying on the wipers to clear it.

Lifting your wipers is not necessary every time you park, but it can be a useful precaution when extreme weather is expected. The most important thing is to avoid forcing frozen blades, inspect them regularly, and replace them when they no longer clear the windshield properly. A small change in your parking routine may help protect your wipers and make winter or summer car care a little easier.
