From safe wash to smoother paintwork.
02 — The visit
Once we arrive, we follow a careful decontamination process designed to remove bonded contamination that normal washing will not fully remove. Our Clay Bar Treatment helps leave the paintwork cleaner, smoother and better prepared for wax, sealant, ceramic coating or machine polishing.
How it works
1. We arrive and check the vehicle
We introduce ourselves, confirm the Clay Bar Treatment booked and carry out a quick walk-around to check the paintwork, glass and exterior condition before any work begins.
2. Safe wash and exterior preparation
The vehicle receives a safe exterior wash to remove loose dirt, road film and surface grime before any decontamination work starts.
3. Clay bar decontamination
The paintwork is treated with a clay bar process to help remove bonded contamination such as fallout, overspray, tree sap, industrial grime and rough surface deposits.
4. Final rinse, protection and walk-around
Once the paintwork feels cleaner and smoother, the vehicle is rinsed, dried and finished with protection where included. We then complete final checks and walk you around the result before we leave.

By vehicle size
Your Clay Bar Treatment price is confirmed before the booking is agreed, based on vehicle size, exterior condition and the level of bonded contamination on the paintwork. This service is designed to remove rough surface contamination and prepare the paintwork for wax, sealant, ceramic coating or machine polishing. If the vehicle needs extra work for heavy tar, fallout, tree sap, overspray or neglected paintwork, we will discuss this with you first — so you know exactly what to expect before we begin.
