Claying, or clay bar treatment as it’s sometimes known, might seem like an advanced detailing step since it's not part of most people's regular car cleaning routine. However, it’s not meant to be a frequent task. Typically, claying is done before applying a polish and sealant treatment, possibly once a year, or even quarterly for some enthusiasts. The purpose of claying is to remove contaminants bonded to the paint surface that a standard wash may not address. An Auto Finesse detailing clay bar works by "shaving" these contaminants away. Common contaminants like tree sap, tar, iron, and other industrial fallout can bond to your vehicle’s paint over time, leaving it feeling rough. These contaminants not only dull the paint’s clarity and shine but can also affect the performance of car wax or sealants, and in some cases, they can damage the finish if left untreated.

What You'll Need - A Clay Bar

Detailing clay bars come in various types and grades. If you're new to claying, it's best to start with a fine or medium clay bar. We wouldn’t recommend starting with an aggressive clay bar, as it may be too harsh for beginners.

Some Glide Clay Bar Lube

For lubrication, you can use dedicated clay bar lubricants, or opt for water-based detail sprays like our Finale. If neither of these is available, a mixture of car shampoo and fresh water in a spray bottle can also serve as effective clay bar lubricant.

A couple of microfibre towels are recommended; it's best to dry as you go.

How To Use A Clay Bar

First, make sure the car is thoroughly washed. If this is your first time using a clay bar, we recommend fully drying the car as well. For detailed instructions on washing your vehicle, check out our car wash detailing guide.

Start by breaking off a manageable piece of your detailing clay bar and knead it in your hands until it becomes pliable. Next, flatten the piece into a small disk shape.

Begin by working in small sections, approximately 1ft x 1ft. Spray your clay bar lubricant generously onto the surface. Glide the clay bar gently over the paintwork, allowing it to do the work without applying extra pressure. As you move the clay bar, you'll notice the surface gradually becoming smoother.

After completing the process (about 4-6 passes should be enough), fold the clay bar with the contaminated side facing inward to expose two fresh, clean surfaces.

Repeat the process on the same area until no more contaminants are being transferred. Then, dry the section and proceed with the same method across the entire car.

In our opinion, it's best to start at the top of the car and work your way down. If you happen to drop your clay bar or a piece of it on the ground, discard it immediately.

Once you’ve finished, we always recommend applying a car polish and protecting your vehicle with either a paint sealant or a high-quality Carnauba wax.
