CarPro Iron X Snow Soap Review

CarPro Iron X Snow Soap Review

If you are not already familiar with Iron X from Carpro, it is probably one of the most popular fallout removers available on the market.

A fallout remover is a special product aimed at decontamination (On Paint and other Surfaces such as Alloy Wheels) that has the chemical ability to help you to remove iron oxide particles from a surface without having to remove them mechanically. These particles are loosened up and agitated via a chemical process that allows for them to be rinsed off safely.

I have already written a huge post on Iron X – so if you have not read it, you can check that out first over here.

During some recent maintenance washes on my car, I noticed that there was some slight buildup of fallout on my paintwork. It was nothing too extreme but I wanted to tackle it ( preferably without having to clay the whole car )

I needed some new snow foam after running out of my highly recommended angel wax fast foam, So I decided to pick up some Iron X Snow Soap. This would hopefully solve my minor fallout contamination issue while doing my weekly wash.

I will be doing a full machine polish on my car again when we move into the summer months, so I will save the full claying job until then, and use Iron X Foam during the winter season to keep the fallout situation under control.

What is CarPro Iron X Snow Soap?

Iron X Snow Soap is marketed as a strong, pH neutral cleaner that can also remove iron contaminates at high concentrations. In theory, this means you will not need to follow up with regular Iron X after washing with Snow Soap.

This Snow Soap claims to open up the pores in the paint as you wash your vehicle, releasing ferrous airborne particles before they can cause further damage.

Snow Soap Features:

  • High Lubricity
  • pH balanced
  • Contains degreasers that cut through road film and heavy grime with ease
  • Produces thick foam that clings to all surfaces
  • Removes ferrous airborne particles
  • Changes color as it interacts with iron particles
  • Clearcoat safe
  • Phosphate-free

How to Use CarPro Iron X Snow Soap?

To maximize the iron removing the ability of this product, CarPro recommends using it undiluted in your foam lance. They recommend a 1:8 mixture (product: water) for light to medium iron removal, and just 1-3 ounces of product in a foam lance for general cleaning when iron removal is not a priority.

It is also recommended that when working on heavily contaminated vehicles you should still use traditional Iron X after washing to remove all of the iron particles, regardless of how you dilute the snow soap.

As I only needed this product for light removal, I used about a 1:8 Mixture in my foam lance. This was not exactly a cheap product by any means, so using high concentrations in your mixture would work out to be quite expensive I would imagine.

CarPro Iron X Snow Soap Review

From a pure snow foam perspective, not taking the iron removing properties into account, the Iron X product seemed to perform well and I can’t fault it there. It did seem to have some great cleaning ability.

Iron X Snow Soap provided a good amount of lubrication, and the dirt and grime were easily removed from the vehicle with little effort.

One thing I did notice is some purple colouration in some of the foam remnants that were left on the floor once the foam had runoff. This is a good sign that some of the Iron was removed from the cars paint/wheels during the foaming process. Exactly what I was looking for from this product.

Once the car was rinsed off fully, I proceeded to wash the car as normal with a wash mitt and shampoo.

Once the car was fully dried off using a microfiber towel – I went to inspect the paintwork to see if it had solved my “minor” iron contamination problem on the paintwork.

It looked like the Car Pro Snow Soap had removed some but not all of the affected areas of the paintwork and there was still some iron remaining.

It had improved the situation.

CarPro Iron X Snow Soap Summary

Given my results above, I’m not sure whether I should have used a more strong concentration of the product in the snow foam lance. If I had used some more it might have had a greater impact on the iron particles on my paint.

However, I will continue to use this product as my snow foam over the next few washes and I’m sure it will gradually clean up the fallout from the paintwork as desired.

One problem I have with this product is the price, it was pretty expensive as far as snow foams go.

It worked very well for cleaning, but many other foams are inexpensive and also clean very well, so the performance did not exactly justify the added cost of Iron X Snow Soap over a regular snow foam.

For full decontamination, I would say this product is not a substitution to simply spraying with traditional Iron X which is considerably cheaper per use – and much more effective.

  • Price 5/10

  • Application 7/10

  • Thickness 6/10

  • Cleaning Power 8/10

  • Overall Score 6.5/10
