How to use a clay bar

Ever washed your car, dried it off, and ran your hand over the paint only to find it still feels slightly gritty? That’s where clay barring comes in.

At Carma, we know that great car paint protection is about more than just a quick soap and rinse. To get that "glass-like" finish, you need to remove the microscopic surface contamination that a standard wash leaves behind. If you’ve never used a clay bar before, don’t worry, it’s a simple DIY car detailing task that makes a massive difference to your car’s shine.

What is a clay bar?

Before we get started on how to use one, it’s a good idea to understand what it is. It is a putty-like tool made of synthetic resin. It is specifically engineered to pull out contaminants that are bonded to your paintwork, things like tree sap, stuck dirt and stubborn bug residue.

There are generally two types of clay bars to choose from:

• Fine grade clay: best for newer cars with very light surface contamination.
• Medium grade clay: ideal for older vehicles or cars that haven't been deep-cleaned in years.

What do I need to start before I start clay barring?

You don’t only need just a clay bar to clean your car. These other things will help achieve the best result:

• Clay lubricant or car wash soap: essential for providing the "slip" needed for the clay to glide safely.
• Microfibre towels or chamois: to wipe away excess clay lubricant as you go and to dry your car.
• Car wax or sealant: this is optional, but it will help protect the freshly cleaned paint afterward.

How do I start using my clay bar?

1. The prep wash

Before you start clay barring, you’ll need to wash your car thoroughly to remove loose dirt and grime. Dry the car completely and park it in a cool, shaded area.
