Driving a Chevrolet Silverado 1500 HD with the truck bed fully loaded prevents you from looking at the rear with the rearview mirror. This means you will have to rely wholly on the two side mirrors when viewing the rear. But the side mirrors can't always be reliable especially when you've just driven through a rainy afternoon the other day and you haven't had time to wipe it dry. This can cause blind spots that may result in an accident. Take a look at some other reasons that bring about some inconveniences with your Chevrolet Silverado 1500 HD mirror glass.
Hard water contains mineral salts such as calcium, magnesium ions, and iron. You could be washing your car with hard water every time but not notice it. And sometimes, when the mirror glasses are not thoroughly wiped and dried, chances are, the minerals will harden and can impede your vision when you use the mirrors. This can also be caused when it rains, since your side mirrors are not at all exempted from getting wet. Although rainwater is naturally soft, as it travels from the clouds, it may collect mineral salts that will eventually make it hard. And when it lands on your mirror glass and not wipe it off, you will eventually see white spots when you look through them. If left untreated, these hard water spots will create stains that will be impossible to remove.
As the mirrors are constantly exposed to external weather and all kinds of debris, they are very prone to scratches. And although the mirrors are made of glass, these can cause scratches on the surface of the mirror glasses that can probably cause distractions to your driving.
The Silverado's glass mirrors are usually made of glass and are breakable under pressure. There are, however, some aftermarket and OE replacement glass mirrors that are made of acrylic, which is a kind of heavy duty plastic. These may be a bit tougher when it comes to the issue on breaking, but are not that safe when it comes to cracks and scratches.
