Windshield water repellents are chemical treatments applied to the windshield of a vehicle to improve visibility during rain or snow. They work by causing water to bead up and roll off the windshield, rather than forming a sheet that can obstruct the driver’s view. This can be especially important in heavy rain or snow, when visibility is already reduced.
There are a number of different windshield water repellents on the market, each with its own advantages and disadvantages. Some repellents are designed to last for several months, while others need to be reapplied more frequently. Some repellents are also more effective in cold weather than others.
