What is rail dust? What causes orange spots? The secret is….
Ugh ! What are those bantam, orange spots on my blank car ? They show up on aluminum a well as metal and I precisely can not scrub them off !
What is rail dust? Rail dust is commonly used to describe the cause of orange dots (rust specs) on the painted surface of a car.   “Rail Dust” describes specs of any ferrous material that lands on a car’s painted surface and creates orange dots of rust. Automobile manufacturers originally coined the condition when it was believed that the process of delivering the cars to the dealer by rail was caused by these orange spots ( rail dust. ) Industrial fallout or fallout are besides coarse terms to describe these minor ferric particles.
What is rail dust? What causes orange spots? The secret is….
Rail dust is the alleged cause of orange spots on white painted vehicles. When I first heard the Ford Service Manager mention the terminus rail dust, I thought to myself, I don ’ thyroxine live near railroad track tracks. How could rail debris be a refer ? ” I do park my truck within 100 yards of a vilify road track. The lead may see two or three trains pass while my truck is in the parking distribute. But….really ?
I have a heavily time believing that spectacles of cast-iron could come off of the track in sufficient quantities to cause Orange spots to form on my and early vehicles within a hundred yards of the chase.

Through all of my research, I discovered that rail dust goes beyond steel particles originating from steel rail cars wheels contacting the railroad track.  Or even rail car brakes that activate to slow the rail car. There’s much more that falls within the definition of rail dust, then just Railroads.
What causes rail dust (orange spots) on white cars?
The orange spots on a flannel car are rust stains ( iron oxide stains ). Tiny metal particles settle on to your car or truck paint. These particles begin to rust and create an orange blemish of rust on and around the specification embedded into the rouge.
There are many names for the orange dots that appear on white cars. My local franchise refers to this as train dust Some name this industrial fallout, or equitable side effect. Brake scatter can be a cause of the orange specks. Any particle that can form rust, iron oxide, could cause the orange dots to appear on your flannel car The orange spots are created when particles from the standard atmosphere farming on a car ’ s surface and embed themselves in the paint.
So who would be at a higher risk of having orange dots created on their car?
The term train dust implies that people who parked their car near a railroad agate line are the most susceptible to orange dots. Although railroads could be a cause of the orange specks, they are not the only cause. People who spend a draw of clock time driving on freeways could notice an increased number of orange dots on their cars because of brake dust particles settling on the cars. People who work an industrial parks could be at a higher risk. Articles from the industrial park can be swept into the air, then settle on to the come on of a car ’ s paint
Why is the back of the car more susceptible to orange spots?
I first discovered orange dots on the tailgate of my white F-150 Ford pickup. I couldn ’ thyroxine understand how material kicked up from the road could hit the tailgate and cause a corrode position. however, after researching the lawsuit of the orange dots, I ’ ve come to realize that small particles are more likely to land on the back of the car due to the airflow as the car drives down the road. The air run around a car whine and edy at the back of the car. The air campaign could dry ice particles to collect there. Another post on this website explains this in more detail.
Why do the orange spots only show up on white cars?
Orange spots show up on white cars because it is easy to see on a white car or other light colored car. The orange spots would be closely inconspicuous on an orange car. Orange spots would be show on a dark-colored car, but more unmanageable to see .

What do the “car guys” say?
initially, I spent a lot of clock time with Google. At that time, forums were the alone source of information. once I researched “ vilify dust ”, Orange spots, industrial fall out, etc. I realized that was the proper text to type into the Google search box to find quality information. This is why I kept the name of the web site identical simple : “ orange spots on white paint. ”
I remember what it was like when I was hearing all kinds of explanations about the informant of the orange spots and “ rail dust. ” So, I wrote this data to pull together many resources.
The data in the future couple of paragraph came from multiple car forums. I ’ ll include these in order for you to gain the context of the problem and allow you to make your own conclusions :

  • When researching, I initially concluded that particles from rail car wheels contacting the steel rails was the cause of all orange spots on white painted vehicles.   Some people actually directed you to the window sticker of your vehicle. It was suggested that if your vehicle was delivered by rail (rather than by tractor trailer or by convoy) then you would automatically be susceptible to rail dust, and later orange spots.   
  • Some people pointed me in the direction of brakes.  Brake dust could be a potential source of the orange dots.  It was suggested that people who drive on very busy highways could be at a greater risk as there would be more exposure to brake dust from other vehicles in traffic.
  • Industrial Fall Out.  It is suggested that people who work in an industrial area where particles will fall out of the air as a result of an industrial or manufacturing process.   Also suggested that certain types of industry may be more susceptible to industrial fall out. Foundries, refineries are commonly suggested as high risk industry by authors in these forums.  Simply put, it was implied that if you park your car near a smokestack, then, expect orange spots.

What is industrial fallout?
Industrial side effect is not a coarse terminus to most of us. however, it is a very common term used by environmental auspices professionals who either measuring stick pollution or develop technologies to protect the environment. sometimes, the environmental protective covering applies to wild life. sometimes, it applies to humans. sometimes, it applies to the paint come on of our vehicles !
The Chroma System Low VOC Technical Manual Glossary ( 2015 ), by E. I. du Pont de Nemours and Company defines industrial fallout as :

“ Chemical compounds confront in the air out which are deposited on the horizontal surfaces of vehicles and which may damage the finish. ”
Industrial Fallout can include any material that can come from a manufacturing/industrial process. This could be ferric metal particles from a foundry or sawdust from a attend factory. Industrial fallout could be any airborne particle that originates in an industrial facility. In the 2004 Technical Service Bulletin, Ford put this into perspective when it defined Industrial side effect as :
“ Ferrous metallic particles ( blistering iron dust ) are generated by manufacturing facilities, rail shipments, Etc. moisture and hotness unite with particles to create a chemical reaction. This reaction creates an acid causing the iron to corrode and etch into the key coat. ”
Considering the country and union ( EPA ) requirements to minimize air befoulment, I question whether industrial side effect is a strong reference for orange spots. In my particular case, there is no industrial fallout within miles of my workplace, yet my truck developed orange dots .

What is in a brake pad that could cause orange spots on my paint?
Two common categories of brake pads are semi-metallic and ceramic brake pads. All brake pads include some total of alloy. The brake drum or rotor itself is composed of ferric metallic element.

The semi-metallic brake pads are the most versatile for all braking characteristics, so more democratic. Semi-metallic pads contain anywhere from 30-65 % metallic element by weight Semi-metallic brake pads consist of sword, iron, copper, etc.
Copper-Free Brake enterprise : In 2015, the EPA, several states, and the automotive diligence signed an agreement to reduce the use of copper and early materials in motive fomite brake pads. The agreement calls for reducing copper in brake pads to < 5 percentage by weight in 2021 and 0.5 percentage by 2025. In addition to copper, this voluntary initiative reduces mercury, lead, cadmium, asbestiform fibers, and chromium-six salts in motor vehicle brake pads.

Wow ! I didn ’ triiodothyronine understand there was therefore much metallic element in a brake diggings. Granted, the brake pads have to wear and need to withstand intense temperature due to clash. however, that is a meaning sum of metal ! actually, the amount of ferric ( iron oxide/rust ) producing metallic element is celebrated.

What are ferrous metals?
ferric metals are highly vulnerable to rusting and corrosion when exposed to moisture or an acidic or caustic environment due to the senior high school content of carbon molecules. normally used ferric metals are : Steel, Carbon steel, Alloy steel, Cast cast-iron, and Wrought cast-iron

ferric metals are those metals that are chiefly composed of iron and have magnetic properties. Some common ferric metals include debase sword, carbon steel, cast iron and cultivate iron. Iron forms Iron Oxide, or rust…..or orange spots on your rouge .

Read enough? Well it gets interesting in the “What do the experts say” paragraph below.

However, if you just want to learn how to remove rail dust, then, here’s a link to an article on this page about the Easiest Way to Remove Rail Dust.
What do the experts say?
In 2004, Ford published Technical Services Bulletin titled Body–Iron- and- fall out Fallout acid Rain neutralization   article number 04- 9- 6. Within this document, Ford list the following cause of orange spots under the “Concern Description” section of the technical service bulletin:
Light colored Vehicles : small orange stains the size of ” mechanical pencil run ” run. The open is roughly to the touch
Dark Colored Vehicles : small white or silver medal appearing dots with rainbow ring around the. The open is rough to the equal
Industrial Fallout : water system spots containing ferric metallic are present in the surface is grating to the touch
Under the ” designation ” section of this Technical Services Bulletin, Ford States :
“ Ferrous alloy particles ( hot iron dust ) are generated by manufacturing facilities, fulminate shipments, Etc. moisture and heat trust with particles to create a chemical reaction. This reaction creates an acid causing the cast-iron to corrode and etch into the paint surface. additionally, industrial side effect and acerb rain generate corrosive compounds that fall on the vehicles painted surfaces. When subject to moisture and temperature, chemical compounds are created that the paint open period to assist in identifying service contaminant use a ( Tandy – Radio Shack # 6 3- 851 ) 30X lighted magnifier ”
What is rail dust? What causes orange spots? The secret is….
How does Ford recommend that these orange spots be removed?
According to the technical services bulletin mentioned above, Ford recommends the follow routine to decontaminate :
decontamination routine :
Use Motorcraft Acid Neutralizer, Alkaline Neutralizer, and Detail Washto decontaminate and neutralize the rouge surface. Perform the procedure alone on vehicle when the paint surface temperature is cool. Follow the bit-by-bit procedure listed below to perform this service operation .

  1. Rinse off dust, dirt, and debris with cold water.  Flush liberally.
  2. 2.  Prepare Motorcraft Acid Neutralizer by mixing eight (8) parts of water to one (1) part Acid Neutralizer in a bucket.
  3. 3. Wear gloves and use a clean wash mitt to apply mixture of Motorcraft Acid Neutralizer to the entire vehicle starting at the top of the vehicle working toward the side.  Work fast and keep the vehicle wet with solution, lightly agitating and moving quickly around the vehicle repeatedly for five to seven minutes (5-7) minutes. For vehicles with severe conditions, work the product for up to eight (8) minutes.

note :
Use a separate baseball glove for each product. Do not intermix mits.
4. Rinse the vehicle thoroughly with cold urine to remove Motorcraft Acid NEutralizer .
5. Dry merely the horizontal surfaces of the fomite at this prison term. Do not dry methamphetamine.
note :
Motorcraft Alkaline Neutralizer is cook to use. Do not mix with urine. Do not spray MOtorcraft Alkaline Neutralizer on the paint surface .
6. Pour the Alkaline Neutralizer into a dispenser ( jet bottle ). Squirt the neutralizer directly onto a clean wash baseball glove. Apply the merchandise to the vehicle, keeping the areas wet and lightly agitated for five to seven ( 5-7 ) minutes.

7. Rinse the vehicle thoroughly with coldness water .
8. Prepare Motorcraft Detail Wash by mixing 29.5 milliliter ( 1 snow leopard ) of Detail Wash to 3.7 Liters ( 1 gallon ) of urine
9. Shampoo the fomite with Motorcraft Detail Wash using a clean laundry hand. Rinse the fomite with cold water and dry the vehicle wholly.
