Car decontamination and protection checklist: free printable PDF
By Sam W - SoapX Ltd.
A normal wash removes dirt. It does not remove the iron particles, tar spots and bonded grime that make paint feel rough and stop protection sticking. This free checklist takes you through a full decontamination and fresh protection in the right order, two to four times a year.

Decontamination & Protection checklist. Two A4 pages, with a protection record so you know when each surface is next due.
What is on the decontamination checklist
| Section | What you tick off |
|---|---|
| Wash | Full wash as checklist 01 |
| Chemical decontamination | Iron fallout remover on paint and wheels, tar and adhesive remover, strip wash (if changing protection) |
| Mechanical decontamination | Bag test, clay bar or clay mitt, rinse and dry fully |
| Prep and protect | Polish (optional), panel wipe, apply protection, keep dry for the cure time, protect wheels, glass and trim |
Every row has space to write the product and ratio you used. The sheet works with any brand, so it suits whatever is already on your shelf.
When to decontaminate
Do the bag test. Wash and dry the car, put your hand inside a thin plastic bag and run your fingertips lightly over the bonnet. If it feels gritty or rough, the paint is carrying bonded contamination. Most cars need it before winter and again in spring.
Why the order matters
| Step | Why it comes here |
|---|---|
| Wash | Removes loose dirt so the chemicals work on what is actually bonded |
| Iron fallout remover | Dissolves metal particles chemically, so there is less for the clay to drag |
| Tar remover | Softens tar and adhesive before anything touches it |
| Clay | Lifts whatever is left. Doing it last means less grit and fewer marks |
| Panel wipe | Removes lubricant and oils so protection bonds to bare paint |
| Protection | Goes on a surface that is properly clean, so it lasts longer |
Keep a protection record
The second page has a table for paint, wheels, glass, trim and interior: what you used, when you applied it, how long it should last and when it is next due. It turns a vague feeling that the car needs doing into a date. Our fallout and tar guide covers the chemical stage in more depth.
How to get the most from it
- Print it on A4. It is designed to work in black and white.
- Write in the product, ratio and dwell time you used. Next time you will know exactly what worked.
- Laminate a copy and use a whiteboard marker if you do the same job every week.
- Save the PDF to your phone so the list is always with you.
Quick answers
How often should you decontaminate a car?
Two to four times a year for most cars. Before winter and in spring is a good rhythm, or whenever the paint fails the bag test.
Do I need to clay after using an iron remover?
Usually yes. Iron remover only dissolves metal particles. Clay lifts other bonded grime such as tree sap mist and industrial fallout.
Can I apply wax straight after claying?
Yes, once the car is rinsed and dry. A panel wipe first gives the best bond, especially for sealants and coatings.
