The claybar has become such an important tool for regular auto detailing that a single page of information really isn’t enough. Throughout the Guide To Detailing website you will find references and how-tips to help you get the most out of your clay bar detailing work. This page offers step-by-step detailing clay information.
Chances are you’re here because you’ve seen detailing clay bar kits in the store or you’ve heard other people talking about it. Perhaps you’ve tried it before and simply didn’t get the results you expected. You’re in the right place.
I have been using clay bars to clean and detail cars since 1997. During the years I was making and selling products, I sold many thousands of them under my Autopia and Sonus product labels, including a custom blend made exclusively for me. I know a lot about detailing clay, its history, its benefits and it’s limitations.
WHAT A CLAY BAR CAN AND CANNOT DO
I read a lot of clay bar product reviews. Typically when someone gives a 1- or 2-star review it’s because they are disappointed that the product did not remove the swirl marks and scratches from their car’s paint. So, I’d like to start with what detailing clay can do and what it can’t.
A claybar is a paint cleaner. Its one and only job is to remove bonded contamination on the surface of the paint (or glass). When properly applied, the claybar itself never touches your paint. It glides over it on a layer of lubrication (detail spray).
The benefit of using detailing clay versus a traditional car polish or cleaner wax (to clean your car) is that claying is faster and it does not physically wear on the paint finish. Other forms of paint cleaning use chemicals and abrasives that thin your paint or clearcoat over time, contributing to premature wear.
Due to the fact that a clay bar never touches your paint, it cannot remove paint imperfections, like swirl marks or scratches, and it won’t improve the shine. What it will do is remove the grunge so you can see a bright, clear finish.
There are several side benefits to using clay, as well. This most noticeable side benefit is how slick and smooth your paint feels after claying. You can polish your car for hours and it won’t feel as slick and smooth as it does after just a few minutes with a clay bar. The biggest true benefit this has is that it makes waxing easier and more effective. With a super slick finish, wax glides on and buffs off with ease. Plus, the contamination-free finish allows for a tighter wax job that lasts longer and looks better.
EVALUATING YOUR PAINT FOR CLAY BAR DETAILING
How do you know if you need to use a clay bar? After thoroughly hand washing your car, feel the surface of your car’s paint. Do you feel bumps and rough spots? These bumps are contaminants attacking the finish of your car.
Removing these surface contaminants (road tar, acid rain spots, bug residue, paint over-spray, brake pad dust, hard water spots, etc.) will improve both the look and health of your car’s paint. By the way, you can magnify your sense of touch by inserting your fingertips into a sandwich bag or a piece of cellophane.
No matter how well you hand-wash your car, many of the contaminants that have worked their way into your car’s paint finish will remain. Have you ever looked at your foam wax applicator pad after applying a coat of wax? What do you think that black stuff is? It’s dirt, and you’re waxing over it, sealing it in.
HOW-TO USE A CLAY BAR TO CLEAN YOUR CAR
Using a detailing clay bar is very easy, but you must follow the instructions. Use a clay bar incorrectly and you will create a mess or scuff the surface of your paint.
Before using detailing clay, you must thoroughly clean and dry your car to remove any loose dirt. Direct sunlight should not fall on your car’s surface, and it’s best if the work area is relatively cool to prevent rapid evaporation of the claybar lubricant. Also, most claybars become soft as they get warm, making them less effective.
To use a clay bar, you spray a lubricant on a small area of your car and rub the clay back and forth with light to medium pressure. If the lubricant begins to dry, you’ll need to spray more. Detailing clay is sticky and cannot be used dry. Try using a clay bar dry and you’ll make a big mess and scuff your paint.
After a few passes with the clay bar, rub your hand over the area you cleaned to check for areas missed. You should feel a distinct difference between the areas you have clayed and the areas you have not clayed. Keep rubbing until all contamination bumps are gone.
Finally, wipe the clay lubricant residue off with a soft microfiber towel, and buff to a nice luster. Just like waxing, it is best to work in small areas. Check the clay bar frequently for hard particles. When found, pick them off. Make it a habit to occasionally knead and reform the bar so that a fresh portion of the bar contacts your car’s paint.
If you drop your bar of detailing clay on the ground, it’s history. Toss it out. Don’t take any chances, discard the clay bar if it becomes impregnated with grit. Read the manufacturers’ directions for the number of uses of their clay bar. Do not overuse your detailing clay.
When you’re finished claying your car, you may need to wash it to remove the lubricant film. If you plan to use a pre-wax cleaner polish it will remove clay residue so there’s no need to wash. After using clay, seal your freshly cleaned paint with your choice of wax or sealant.
Automotive detailing clay isn’t just for paint. You can use detailing clay on any smooth, hard surface, including glass and chrome. Do not use clay on clear plastic, such as headlight lenses.
When I can no longer remold clay to get a clean surface, I retire it for use on my windows. The dirty clay will not harm glass, and it’s amazing how much dirt film clay can remove from your exterior glass.
I also use my old clay to clean wheels. Detailing clay will safely remove stubborn, embedded brake dust, tar and road film from all factory wheels. I do not recommend using a clay bar on wheels that do not have a factory clearcoat or powder coat finish.
CLAY BAR DETAILING FACTS
Over the past ten years I have received a lot of email questions regarding clay bars. Here are some common questions and answers:
Q1. I dropped my clay bar on the ground. Can I still use it?
A1. The safe answer is no. A clay bar will pick up small particles of grit from the ground that will scratch your paint.
Q2. If I clay bar my car do I still need to polish my paint?
A2. Yes. Detailing clay will not remove swirl marks, scratches or etching from acid rain or hard water spots. Paint polish is still required to remove these paint defects. If your paint is new or like-new, detailing clay will significantly reduce the amount of polishing required to keep your paint in good condition.
Q3. What is the best claybar?
A3. What label do you like? There are only a couple manufacturers of clay, and the technology is protected by U.S. patents. Clay is manufactured with different levels of abrasiveness and colors to suite different applications. There are some subtle differences in technology (plastic vs. elastic material) and the firmness of the material. In general, softer clays are safer and easier to use. A firm claybar cleans better with a little more risk of scuffing or scratching.
Q4. Is it better to use soapy water or a detailing spray for lubrication.
A4. Both work equally well. If you want to do the job fast, use a bucket of soapy water. If you want to work inside or do a thorough job, use a spray lubricant. With a spray lubricant you can wipe down each panel as you go and feel for areas you missed.
Q5. How do I store my clay bar?
A5. If your clay bar did not come with a re-usable plastic container, store it in a Ziploc baggie.
Q6. Will a clay bar remove my wax?
A6. In most cases, a clay bar will “scrub off” wax protection. Some paint sealants are hard enough to withstand being cleaned with clay, but most are not.
POLISHING AFTER CLEANING
Many people assume that a detailing clay bar completely replaces car polish. While it’s true that detailing clay does the heavy lifting, it does not replace the need to use a car polish cleaner.
The car polish I use and recommend the most is Klasse All-In-One. Nothing I’ve tried applies, wipes off and delivers the same great results as Klasse All-In-One paint polish and cleaner. To learn more about Klasse, see my Klasse Car Wax Guide.
When cleaning or polishing paint, always work in a shaded area, out of direct sunlight. Polishes and cleaners do not work well on hot surfaces. Work on one area at a time, covering 2 to 4 square feet. Buff off the polish residues as you go. Most car polishes do not need to dry or haze before being wiped off, but be sure to follow the manufacturer’s instructions.
You can use a foam, terry cloth or microfiber applicator pad to apply car polish. If your paint finish is in new or like-new condition, I recommend a quality foam applicator. If your paint is moderately oxidized, I recommend a microfiber applicator.
Use a small amount of car polish at a time. With most products, several pea-size dabs is enough to clean and polish an area of 2 square feet. If the polishing residue does not buff off easily, switch to a clean wipe towel. For best results, I recommend using a microfiber polishing towel.
After cleaning, your car’s paint should be squeaky clean, smooth, and free of streaks and minor swirls. It’s now ready for waxing.
