Do I need to wash my car after I use detailing clay to clay the paint?

This is a very common question...

Here's the skinny...

Claying after washing and drying

The most common process is to wash and dry the car, then after drying the car, clay the car section-by-section and after claying a section, while the surface is still wet with your clay lubricant, use a microfiber polishing cloth to wipe that section dry.

Some people may choose to wash and dry the car a second time after the claying process to insure all residue and any loosened dirt or abrasive particles are completely removed. This would be on the AR side of the spectrum because if you do a good job of wiping the paint clean with a good quality microfiber polishing cloth immediately after claying a section then for the most part that section is clean and ready to work on.



Claying while washing but before drying
Another way to clay the paint that is common and popular with professional detailers is to clay the paint during the washing process while the car is still wet as a step-saver to reduce the amount of time invested in the job in an effort to maximize profits.


Three Factors - Time, Labor, Profit


Enthusiast Detailer
If you're an enthusiast detailer, only working on your own cars then time, labor and profit are not usually factors that influence your process. You can invest as much time and labor into your car because your profit is your enjoyment of the process and the results.


Professional Detailer - Anyone detailing a car for money
If you're a processional detailer then you understand that your profit is directly determined by the amount of time you invest into the job plus the cost of materials. Your labor is a given if you're working by yourself and if you hire workers to help you then the cost of their labor must also be factored in.

Because profit is greatly influenced by the amount of time invested into each job, it's only natural to look for ways to save or reduce time. One way is to clay the car immediately after washing the car but before drying the car. The goal is to save a step by not having to dry the car after washing and the re-wetting the car with a lubricant to clay the car and then drying or wiping the car a second time to remove the lubricant. The goal being to get a car washed, clayed and then dried with as few steps as possible.


Clay the car after washing but before rinsing
Some detailers will wash the car and as mentioned above, clay the car after washing each panel using their car wash solution as the lubricant. I've called on and worked with detail shops where the detailers kept their clay bars in their buckets of wash soap as a normal practice. I personally wouldn't recommend this practice as it would be too easy to contaminate the clay but I've seen this done at a lot of production type detail business.

The problem with the above process is that after you wash a car or even just a panel what you have effectively done is loosened dirt, road grim and abrasive particles on the surface and if you now run a clay bar or clay patty over this surface you could grind any of the loosened dirt particles into the clay bar and over the paint possibly scratching the paint.


Clay the car after washing and rinsing but before drying
A better variation of the above is to wash the car, then RINSE the car thoroughly, with a lot of emphasis on the word thoroughly to insure all loosened abrasive particles have been flushed off the car. Now while the car is still wet with rinse water but free from any loosened dirt or abrasive particles, now use detailing clay and a clay lubricant or your car wash solution by dipping your clay bar into your bucket of car wash soap to clay the various panels on the car and then give the car a final rinse before drying.

The above variations of claying after washing but before final drying can all save a detailer some time, the important thing is to focus on the task at hand and do everything you can to avoid instilling scratches into the paint during the claying process. There are some that will say even if the paint is accidentally scratched during the process that it's no big deal as these scratches will be removed in the next steps when the paint is polished and then waxed.

How dirty a car is will also be a huge factor as it relates to any potential for inflicting scratches during the claying process especially if a person chooses to clay the car immediately after washing a panel but before rinsing the panel and flushing off all the loosened dirt, road grim and abrasive particles.


There's no hard rule that says any of the above methods is better than the other because it really comes down to personal preference and even skill level. Lots of Pro detailers are completely able to do any of the above with no problems at all yet I've read threads on forums where usually an enthusiast has tried one of the step-saver methods above and accidentally inflicted scratches into their car's finish.


My take...
My personal preference is to wash and dry the vehicle and then use a dedicated spray detailer formulated for detailing clay and clay the car using a dedicated claying process and after claying each section, wipe the section clean and dry using a microfiber polishing cloth.

Personally, I go ahead and wash, rinse, water blade most of the water off, use my clay and lube to go ahead and clay, and then wash again, rinse, and dry. But that's just me.
 
that seems like the thorough way 2 go ciera....its lookn like a tuff call 2 make, but clayin b4 rinsing seems like a solid split
 
I have always washed and rinsed a car, then pulled it in the garage and clayed it with clay lube, then pulled it back out and washed and rinsed it again, then dried.
 
Hey Mike, speaking of using MF towels after claying, do you really see any difference between a towel that has a 70/30 blend- to a 80/20 blend?
 
Any quality microfiber should work, I usually use whatever I have that's clean and ready to go.

:)

exactly!! i have never had to rewash a car after claying. I have always kept the area very wet with detail spray while claying and make sure i wipe it off right away. its a very simple process.

i have never had to use a certain type of microfiber towel, i just use any good clean one laying around.
 
what microfiber towels do you guys use for QD. the cobra delux 600 is what I use.
 
Hey mike, great information on how to wash and clay cars..
Point noted, it will definitely be more useful..
Thanks for sharing the tips..
 
Next question....

At this time that we are washing the vehicle after claying, do we still using a soap that will strip the wax such as Dawn? Or just rinse with a hose.
 
I would think a waterless or rinseless wash would be a good compromise who want the confidence that the paint is clean.
 
I believe I read a previous post by Mike P. in another thread stating we should not make rocket science out of everything and try to keep it simple. I completely agree with his statement.

With that being said, let me share what I have noticed when it comes to claying.

I washed and completely dried off the car with MF towels. Then I proceeded to clay the car with a dedicated QD (Meg's Last Touch) and wiped each panel dry with a MF towel.

Are we in agreement that the paint should squeak if you rub your finger on it and it has no wax, oils, etc. sitting on the surface?

Well from what I have seen, the paint did not squeak. This tells me the QD is bonding to the paint and is not completely removed only by wiping the panel with a MF towel.

If a QD is designed to enhance gloss and boost the durability of wax then is it not leaving something on the surface to accomplish this?

In certain cases, this does not matter. If you are simply applying a sealant or a wax after then it should be fine, however if you are polishing the car afterwards, meaning you want to see the true surface, making sure the paint is completely bare is essential in my opinion.

If you choose to wash your car after claying it, might as well use some soap for it's cleaning and lubricating features.

People will argue over using detergent soaps or not using detergent soaps till the cows come home so I'll leave your choice of soap up to you... if you're going to do a full correction or then it probably doesn't matter if it's a clear coat finish. If it's an antique, or even older single stage paint then I would avoid detergent soaps for any step.

The important thing is to remove anything off the car before you begin to do the next step... in other words... work clean... like a surgeon.

I believe I read a previous post by Mike P. in another thread stating we should not make rocket science out of everything and try to keep it simple. I completely agree with his statement.

I still stick by that statemen... it's a normal trend for "online" enthusiasts to start getting deep into detailing and the results are usually taking things that are fairly simple and over-complicating them. Nothing wrong with that if you have the time and inclination.

Usually if paint is really clean, and your finger is really clean, then the paint will be squeaky when you rub your finger against it. Washing and claying will remove most of what's on the surface but not always 100%

If you're going to do a full correction or even light polishing, your first step after claying will remove anything left on the surface.



If a QD is designed to enhance gloss and boost the durability of wax then is it not leaving something on the surface to accomplish this?

Yes.

One thing for sure is the chemistry behind car care appearance products is continually getting more advanced.

So many times I've seen this question and it's nice to see some definitive information.

Great post Mike. :props:

Is the squeak test a good procedure to use in order to determine if the paint is really bare? Is it a reliable way to determine if anything is on the paint surface?

When you mention that the first step after claying will remove anything left on the surface, do you mean any machine polishing with a pre-wax cleaner, or any mild abrasive polish in general will remove any residue that will still be on the paint?

Would soaking the car in something like an APC or a degreaser after claying also work?
