Car Underbody Cleaning & Rust Protection in Devon & Somerset
The underside of your car takes everything the road throws at it. I clean the chassis, arches and underbody thoroughly, then apply protection to hold rust at bay, all done on a ramp at our Cullompton studio.

Send me the make and model and a couple of photos of the underside or arches if you can. I'll let you know what it needs and what it will cost.
Why protect the underbody?
Most people keep the paintwork clean but never see what's happening underneath. Salt from gritted roads, mud and standing water get packed into arches, sills and chassis rails, and that's where rust starts. By the time it shows on the outside, the damage is often already done.
A thorough clean and a good layer of protection keeps that metal sound for years. It helps with MOTs, protects resale value and is especially worthwhile on classics, 4x4s, vans and any car you plan to keep.
How it works
Step 1
Inspection on the ramp
Your car goes up on the ramp so I can see the whole underside properly. I check for existing surface rust, damaged coatings and any areas that need extra attention, and talk you through what I find.
Step 2
Deep clean
The chassis, subframes, suspension and wheel arches are washed and degreased to remove mud, road grime and salt. Arch liners can be removed where needed so nothing is left trapped behind them.
Step 3
Drying and preparation
Everything is dried thoroughly before any protection goes on. Loose surface rust is treated so the protection bonds to a sound, clean surface rather than sealing dirt in.
Step 4
Underbody and cavity protection
A durable underbody protection is applied to exposed metal and chassis components, with cavity protection for sills and box sections where water and salt tend to sit.

Questions
Why does the underside of a car need cleaning?
Road salt, mud and water collect under the car and in the wheel arches, especially over winter. Left there, they hold moisture against the metal and speed up corrosion. A proper clean removes it before it does lasting damage.
Is underbody cleaning done at your studio or mobile?
Underbody work is best done at our studio at Unit 1A, Venn Farm, Cullompton EX15 1QN, where the car can go on a ramp. That lets me reach everything properly. Most of my other services can be carried out mobile or at the studio.
When is the best time to have it done?
Before winter to protect the car ahead of salted roads, and again in spring to wash off the salt that has built up. It's also well worth doing on classic cars, 4x4s and any car you plan to keep for a long time.
How long does it take?
It depends on the size and condition of the car, but most underbody cleans with protection take a full day so everything can dry and cure properly.
How much does it cost?
Every car is different, so I quote individually. Send me a message on WhatsApp with the make, model and a couple of photos and I'll give you a price.
