A car’s paint is made up of multiple layers and, at a surface level, may seem completely smooth. However, the surface of a car’s paint has many small pores that capture contaminants with fine particles, such as dust and dirt, as the car drives and sits.
Clay bar is a great auto detailing tool that is made up of a sticky resin compound that is able to pick up these small contaminants.
When a driver applies a clay bar to the surface of their vehicle’s paint, the clay bar reaches into the paint’s pores and picks up the small contaminants that rest in the pores with its adhesive residue, giving the vehicle a much better shine and appearance.

Clay bars are split into three strengths; fine, medium, and heavy-duty. Fine grade clay bars are great to use on most paint surfaces and present the least risk for damage. Medium grade clay bars can be used for more-involved applications. Heavy-duty clay bars, however, should be used carefully as they are the most abrasive of the three types and pose the greatest risks.
Glass-cleaning clay bars

Benefits of using a clay bar
Clay bars remove contaminants that exist in the air and get trapped on the surfaces of cars. Even when new, cars often have flaws in the surfaces of their paint that can be corrected with clay bars.
In fact, brand-new cars commonly have rail dust on their paint from sitting in shipping yards before they are transported to their destinations.
By removing these contaminants, clay bars are able to restore the shine of cars and prepare the cars for any additional detailing that needs to be done.
How to use a clay bar
Using a clay bar is a simple process that you will learn quickly. You will first need to wash and dry your car so that its paint is properly prepared for the clay bar. Washing the car will remove large particles that can potentially scratch your car’s paint as you clay the car.
Once you have washed and dried your car off, you will need to break your clay bar into a few pieces. If you drop a piece of clay bar, you cannot use it on your car, because the debris from the ground will scratch your car’s paint. Therefore, having extra pieces of clay bar can come in handy.
Apply clay lubricant to a small section of your car’s surface and slide the clay bar back and forth on top of the lubricant. As the lubricant dries up, continue to apply lubricant so that the clay bar can work effectively and so that the paint isn’t damaged.
Continue working back and forth on the same section until the clay bar slides smoothly without picking up additional contaminants. You will then need to move onto another section of your car.
Continue the claying process until the surface is free of contaminants, which you will be able visibly see on the pieces of clay that you use.
