How to Clay Your Car



Every car enthusiast knows that a shiny, smooth car isn't just about a fresh coat of paint. Over time, our cars are exposed to various contaminants like road grime, brake dust, and air pollutants that can stick to the paint. This is where the clay bar comes in.

Clay bar treatment in the auto industry is a deep-cleaning process. Clay bars remove scratches and marks that sits on top of your vehicle clear coat, giving your car a smooth finish and ensuring that waxes and sealants work effectively. Not only does it enhance the appearance of your vehicle, but it also protects the paintwork. Before diving into the process, let's understand the tools and techniques that make clay bars so effective.

When to Clay Your Car


Clay bar is a fantastic way to deep-clean your car's paint, but how do you know when it's time to give your vehicle clay bar treatment? Here are some signs and situations that indicate it might be time to reach for that clay bar:

Rough Spots:


Run your fingers over a clean section of your car's paint. If painted surfaces feel rough or gritty, even after a car wash, it's a sign that contaminants have bonded to the surface. Clay bar treatment can help remove these and restore a smooth finish.

Visible Contaminants:

Over time, tiny metal particles, often from brake dust, rail dust, or industrial fallout, can embed themselves into the car paint. These might appear as tiny rust-colored specks, especially on white or light-colored cars. According to Fortador, Clay bars are often used to remove contaminants like rail dust, loose debris, bug residue, and rough spots from the clear coat of a car's paint

Before Applying a Protective Layer:

If you're planning to apply a new coat of wax, sealant, or ceramic coating, clay bar treatment beforehand ensures a clean, contaminant-free surface. A traditional clay bar allows the protective product to bond better and last longer.

Water Beading:


After a rain or an automatic car wash, if water isn't beading up well on your car's surface, it might be an indication that contaminants are affecting the paint's hydrophobic properties. A clay bar can restore this.

Frequent Exposure to Elements:

If you park your car outdoors regularly, especially in industrial areas or near train tracks, it's more likely to accumulate contaminants. Use a clay bar on your car at least twice a year in such cases.

After a Long Winter:


Road salt, grime, and other winter-related contaminants can take a toll on your car's paint. As spring arrives, it's a good idea to clay your car as the clay bar removes these winter remnants.

Before a Special Event:

If you're showcasing your car at an event or simply want it to look its best for a special occasion, a clay bar can give it that extra shine and smoothness.

Tools Required to Use a Clay Bar

Specific tools are required to use a clay bar to ensure the process is effective and safe for your vehicle's paint. Here's a breakdown of the essential tools:

Types of Clay Bars and Clay Bar Alternatives:

Traditional Clay Bar:

These are the most common type and come in different grades, from fine grade bars to aggressive. They're perfect for most cars, especially if you're using a clay bar for the first time.

Synthetic Clay Mitts and Pads:

These are newer alternatives to traditional clay bars. They can be attached to polishers or used by hand and are often more durable.

Importance of Clay Lube and Types Available:


Lubricants are crucial when clay barring. They reduce friction, ensuring the clay glides smoothly over the paint and preventing any scratches. There are dedicated clay lubricants, but some detailers also use a mix of water and car shampoo.

Microfiber Towels: Purpose and Selection:


After the clay bar, you must wipe off the excess lubricant and any contaminants lifted by the clay. A Microfiber towel is perfect for this, as it is soft and won't scratch the paint. They're also great for buffing the car to shine afterward.

Step-by-Step Guide to Clay Bar Your Car


Using clay bars might seem intimidating if you've never done it before, but with the right tools and a bit of patience, it's a process that can yield fantastic results. Here's a simple guide to help you clay your car effectively:

Preparation for Clay Bar:

Start by the car wash to remove any loose dirt or embedded contaminants. A good car shampoo can help ensure the surface is as clean as possible.

Dry your car completely using a microfiber towel or a car dryer.

Choose Your Clay Bar Kit:

If your car has never been clay barred or it's been a long time, consider starting with a fine grade clay bar. For cars with more contaminants, a medium grade clay bar might be more suitable.

Use Detailing Spray for Surface Lubrication :

Use a spray bottle to spray a generous amount of clay lubricant on a small section of the car's surface. It's best to work in sections, like half a door or a quarter of the hood, to ensure the clay lubricant doesn't dry out.

Use Clay Bar on the Clean Surface:

Apply clay to the lubricated area using a clay mitt or clay bar. You'll feel resistance at first, but clay bars will move more smoothly as contaminants are lifted.

Fold and knead the clay bar regularly to expose a clean surface and ensure you're not rubbing contaminants back onto the car.

Wipe and Check the Clay Bar:

After claying a section, wipe it down with a clean microfiber towel. Feel the paint with your hand; it should be smooth and free of bumps. If not, repeat the clay bar process for that section.

Finish Up Detailing Clay Bar:

Once you've clay barred the entire car, give it another wash to remove contaminants or any residual lubricant. Consider applying a wax or sealant afterward to protect the freshly cleaned paint and enhance the shine.

Remember, clay bar is about patience and attention to detail. Take your time, and you'll be rewarded with a car that looks and feels like new.

Maintenance After Clay Barring


Clay Bars do wonders for your car's paint, leaving it smooth and free from contaminants. However, after detailing clay, it is crucial to ensure that the pristine condition of your vehicle is maintained. Here's how you can take care of your car after a thorough clay barring session:

Apply a Protective Seal:

After detailing the clay bar, your car's paint is in its purest form, making it the perfect time to apply a protective layer. Consider using a quality wax or sealant to shield the paint from contaminants and UV rays. This will also enhance the shine and make future detailing clay easier.

Regular Washing:

Stick to a routine car wash schedule using gentle car shampoo. This will help remove contaminants before they have a chance to bond to the paint again. Check out the Detailing Expressing Wash and Dry Collection.

Use Quick Auto Detailers:

In between washes, consider using a quick auto detailing clay, as the clay bar removes light dust, fingerprints, tree sap, and bird droppings. It's a great way to maintain the shine and protect the paint.

Avoid Parking in Polluted Areas:


If possible, try to avoid parking your car in areas with high industrial pollution or near construction sites. These places can expose your vehicle to contaminants that can quickly bond to the paint.

Shelter Your Car:

Whenever possible, park your car in a garage or under a carport. This will protect it from direct sunlight, rain, tree sap, and bird droppings, all of which can affect the paint over time.

Reassess Periodically:

Every few months, do the "smoothness test" by running your fingers over the paint. If it starts to feel rough again, it might be time for another session of detailing the clay bar.

Common Mistakes to Avoid When Claying


Clay bar kits can transform the look and feel of your car's paint, but it's essential to properly clay bar. Here are some common mistakes to watch out for and how to avoid them:

Not Using Enough Spray Lubricant:


The lubricant spray ensures the clay glides smoothly over the paint, reducing the risk of light scratches. Always keep the surface well-lubricated.

Using a Dirty Clay Bar:

If your clay bar picks up a lot of dirt or falls on the ground, it can scratch the paint. Always fold and knead the clay bar to expose a clean, smooth surface. If it's too dirty, it's time for a new clay bar.

Use a Clay Bar in Direct Sunlight:

The sun can cause the lubricant to evaporate quickly, making the smooth surface sticky and increasing the risk of scratches. It's best to apply clay bars in the shade or indoors.

Skipping a Car Wash Before Claying:

Detailing clay on a dirty car can drag loose contaminants across the paint, leading to scratches. Always start with a thorough car wash using quality car shampoo.

Not Checking Your Work:

After using a clay bar, always feel the paint job. If it's not smooth, you might need to use a clay bar again. Ensuring each section is perfectly smooth will give the best results.

Forgetting to Protect the Paint After Clay Bar:


Clay bars strip away any existing wax, ceramic coating, or paint sealant. After the clay bar, it's essential to protect the paint with a clear coat of wax or paint sealant to keep it looking great and protected from the elements.

By avoiding these common mistakes, you'll ensure that your car's paint remains in top condition and looks completely clean after detailing the clay bar.
