Can Windshield Washer Fluid Be Left in the Car During Summer?
2 Answers
Windshield washer fluid can be left in the car during summer. Automotive windshield washer fluid is a tool for keeping windows clear and is also a consumable item. In dusty or rainy/snowy weather, it's advisable to keep a few extra bottles in the car for unexpected needs. It is safe to leave windshield washer fluid in the car during summer, so you can use it with confidence. Windshield washer fluid serves functions such as cleaning, lubrication, antifreeze, and antifog. When purchasing windshield washer fluid, it's mainly based on your living environment—for example, in winter, you should choose antifreeze-type windshield washer fluid. Windshield washer fluid is a cleaning solution for car windshields and comes in various types, including summer-type, antifreeze-type, special-effect antifreeze-type, and concentrated mix-type windshield washer fluids.
It's a common practice to keep windshield washer fluid in the car during summer, which I usually do, especially for long trips in case the windshield gets dirty and needs immediate cleaning. However, in hot weather, the plastic container of the washer fluid may expand, deform, or even leak if it's overfilled or exposed to direct sunlight. I once experienced the bottle bulging, but fortunately, it didn't burst. The washer fluid itself is typically freeze-proof and evaporation-resistant, but prolonged storage may cause some alcohol content to evaporate, reducing its cleaning effectiveness. It's advisable not to place too heavy items in the engine compartment; the shaded area of the trunk is more suitable. Regularly tightening the bottle cap can prevent leaks. Actually, keeping a moderate amount is fine as long as you don't stockpile too much and use it up in time.
