Keeping your vehicle’s paint clean goes beyond regular washing. Over time, contaminants bond to the surface of your paint and require specialized processes to safely remove them. Below is a complete guide to understanding paint contamination, why decontamination matters, and the safest modern methods for restoring your vehicle’s finish.
What Is Contamination?
Contamination is an accumulation of particles from various sources that are mechanically and chemically bonded to your paint. Contamination is not removed through regular washing, though it will not accumulate as quickly with a good maintenance schedule.
Contamination comes from brakes, exhaust, industrial fallout, and minerals. Every time you touch the brakes, microscopic metal particles float out from your wheels, and some attach themselves to your paint. When parked, your vehicle is under constant attack from many things sitting on the paint. Add the sun into the mix, heating the paint, and some of those particles embed themselves into the paint surface.
The contamination that many can’t see or feel is mineral contamination. As you drive on wet roads, there are minerals in the water that attach themselves to the paint, filling the pores.
Why Doesn’t Washing Remove Contaminants?
Regular washing will significantly reduce the accumulation of contaminants, but unfortunately will not remove all of them. Paint on a vehicle is soft and porous, meaning it holds on to contaminants. Specialized chemicals and tools are required for effective and safe removal of contaminants.
What’s the History of Decontamination?
Before the advent of modern clear-coat paint systems, single-stage paints were less prone to contamination. The reason is that as the paint aged, it oxidized, and when the oxidation was removed, it took the contamination with it.
When clearcoats became popular, the accumulation of contamination became more of an issue. Detailers started using wheel acids to remove contamination. While somewhat effective, this also damages the clearcoat.
The next evolution was the clay bar. This abrasive polymer mix (it doesn’t contain clay, it was named clay bar because of its feel and consistency) is excellent at removing bonded contamination, but it can also easily mar the paint, much like a very fine sandpaper.
What’s the Safest and Most Effective Way of Decontaminating Paint?
Today, it’s easy and safe to decontaminate your paint. Clay bars have given way to synthetic decontamination towels, and wheel acids have been replaced by safer and more effective alternatives.
The modern decontamination process uses four products in harmony to quickly and safely deal with all forms of contamination.
The 4 Steps of Modern Paint Decontamination
Wash
Mechanical Decontamination
Iron Oxide Removal
Mineral Removal
We’ll expand on each of these below.
The First Step in Decontamination: Washing
As noted above, washing does not remove contamination, but it’s an important step in the decontamination process. A thorough wash prepares the surface for decontamination.
You want to completely remove all grit and traffic film from the surface before proceeding with decontamination.
DIY Detail Iron Remover is a highly concentrated formulation that removes the rust stains caused by brake dust when it comes in contact with moisture. You can easily see this on light coloured vehicles, especially behind the wheels and the back face of the vehicle.
DIY Detail Iron Remover, despite its name, doesn’t remove the iron particles (it’s a term inherited by the industry). DIY Detail Iron Remover removes the iron oxide (rust) stains in the paint.
The perforated synthetic polymer surface safely plucks the contaminants out of the paint and releases them into the wash bucket. The plush microfiber backing provides protection from pressure points and holds lubrication for safe and effective removal of bonded contaminants.
Used in conjunction with adequate lubrication, it’s safe to use on all exterior automotive surfaces.
How Do I Use the DIY Detail Quad Fold Decontamination Towel?
When done with the contact wash, do not rinse the vehicle.
Take the DIY Detail Quad Fold Decontamination Towel from your wash bucket and fold it in 4. Next apply 1 spray of DIY Detail Iron Remover to the towel and one to the panel.
Deposit the towel on the surface where the DIY Detail Iron Remover was sprayed. Without applying pressure to the DIY Detail Quad Fold Decontamination Towel, move it over the surface. In many cases, you will be able to hear and feel the towel working.
When the surface feels smooth, move to the next panel.
For each subsequent panel, move to a new face of the towel, and spray DIY Detail Iron Remover on the towel and on the panel and repeat.
Once all 4 sides of the towel have been used, dunk it in your wash bucket and continue.
Using the DIY Detail Quad Fold Decontamination Towel in conjunction with the DIY Detail Iron Remover gives you ample lubrication while removing the iron particles, leaving the DIY Detail Iron Remover to only deal with the rust stains.
Once the vehicle has been treated, rinse thoroughly.
What’s the Most Ignored Decontamination Step?
Mineral decontamination is often skipped. Many don’t see the need until they do it, then it becomes clear that it’s very important to proper decontamination.
DIY Detail Water Spot Remover is a lactic acid-based solution that is designed for cleansing minerals from the surface of the paint.
This step will improve the durability of your paint, give beading back to your protective products, and improve the clarity of your paint.
How Do I Do a Mineral Cleanse?
The mineral cleaning portion of a full decontamination is very easy.
After the mechanical and iron decontamination, rinse the vehicle thoroughly.
Using a short nap microfiber towel (we like the DIY Detail Level One towels for this), agitate the DIY Detail Water Spot Remover into the surface.
By spreading and agitating, the surface will be freed of its mineral deposits and be ready for polishing or protection once rinsed and dried.
How Often Do I Need to Decontaminate My Vehicle?
The answer to this question is: it depends.
There are many factors that affect how quickly contaminants accumulate.
Recommended Decontamination Schedule
Average vehicle: Two times per year
Garage kept and fair weather vehicle: Once per year
Daily commuter exposed to traffic and weather: Every 2–3 months
How Do I Know My Vehicle Is Contaminated?
There are many signs that indicate it’s time to decontaminate your vehicle.
Common Signs of Paint Contamination
The water sits flat on the surface with no beading or sheeting
The surface feels rough, like fine sandpaper
Visible rust stains on light paint
The vehicle gets dirty quickly and is hard to wash
The vehicle was winter-driven on salt-treated roads
Final Thoughts
Decontamination is important before doing any form of polishing or applying protection. Properly removing bonded contaminants helps restore gloss, improve protection performance, and maintain the long-term health of your vehicle’s paint.
