Winter is rough on cars in the North East. Months of road salt, industrial fallout, cold mornings, and wet boots accumulate into a genuine maintenance problem. Spring is the right time to deal with it properly — before warmer weather and UV exposure makes the damage worse.
This is the checklist I work through when getting a car post-winter. You can do a lot of this yourself; some of it benefits from professional attention.
Step 1: A Proper Wash to Remove Salt and Grit
Don’t start with a quick hose down. After winter, there’s months of salt embedded in paintwork, wheel arches, door shuts, and the underside. A surface rinse doesn’t reach most of it.
What to do:
- Start with a thorough pre-wash — a snow foam left to dwell for a few minutes loosens salt and grit before you touch the paint
- Use a pressure washer to flush wheel arches, door shut edges, and underneath the rear bumper where grit packs in
- Two-bucket hand wash with good shampoo (Bilt Hamber Auto-Foam as a pre-wash, then Gyeon Bathe or Autoglym Bodywork Shampoo for the contact wash)
- Pay attention to the door shuts, fuel cap area, and boot shut — salt accumulates in all of these
The goal at this stage is removing loose contamination so you can see what’s actually on the paint. What’s left after washing often tells you what step comes next.
Step 2: Paint Decontamination
This is the step most people skip, and it matters more in spring than any other time of year.
Road salt isn’t the only thing on the paint. There’s iron fallout from brake dust, industrial particles from Teesside’s industrial sites, and tree sap or bird dropping residue from the warmer days you got in February. These bond to the paint surface and don’t wash off.
What to do:
- Iron remover: Apply Bilt Hamber Korrosol or similar — it bleeds purple as it reacts with ferrous contamination. You’ll often be surprised how much is on there. Leave it to dwell, then rinse.
- Clay bar or clay mitt: After iron removal, run a clay mitt or clay bar over the paint with plenty of lubrication. This removes any remaining bonded contamination. If your paint feels rough after washing, this is why.
After decontamination, the paint should feel smooth. If it still feels rough, do the clay stage again.
Step 3: Inspect for Winter Damage
With a clean, decontaminated surface, you can now see what’s actually happened over winter.
Check for:
- Stone chips — particularly on the bonnet, front bumper, and along the sills. The A66 and A19 throw up road grit all winter. Even careful driving accumulates chips.
- Paint scratches from badly fitted winter mats sliding, or from loading/unloading in the dark
- Swirl marks — winter hand washes in the dark with cheap cloths often cause these
- Rust spots on wheel arches, sills, or around chips that weren’t treated quickly
- Salt crystallisation around shut edges
For chips that have reached bare metal, treat them as a priority. A small application of touch-up paint prevents rust from taking hold. Larger chips are worth taking to a professional.
For swirl marks and light scratches, this is a good time to consider a gloss enhancement service before applying spring protection.
Step 4: Underbody Check and Clean
The underside of your car has taken more abuse than anywhere else. Road salt sits in areas with poor drainage and causes corrosion — particularly on older cars without full undercoating.
What to do:
- Use a pressure washer to flush the underside. Get under the wheel arches, behind the subframe, and along the sill channels where water and salt pool.
- Look for surface rust on suspension components, exhaust, and subframe areas. Surface rust (orange-brown flaking) is normal on some components; heavy pitting or flaking on structural areas is worth flagging to a mechanic.
- If you’re keeping the car long-term, consider Waxoyl or similar underseal treatment on exposed areas.
You don’t need to be a mechanic to spot obvious issues. Use a torch, look underneath, and if anything looks worse than surface rust, get it checked.
Step 5: Interior Deep Clean After Winter
Winter interiors take serious punishment. Wet and muddy boots, salt dragged in on shoes, de-icer spray, wet coats on the back seat, and months of the windows steaming up. The result is usually musty carpets, salt-stained floor mats, and interior surfaces that haven’t been properly cleaned since October.
What to do:
- Remove mats and clean separately — scrub them properly, not just shake them
- Hoover thoroughly under the seats and in footwells where salt and grit has packed in
- Wipe down all interior plastics with a proper interior cleaner — salt residue on door sills and kick plates causes long-term damage
- If the carpets are stained, they need more than a hoover — a fabric cleaner like Cartec Interior Foam or a proper hot-water extractor
- Leather seats: clean with a dedicated leather cleaner and condition afterwards. Cold weather dries out leather, and unprotected leather after winter often shows early cracking.
If the interior is genuinely in bad shape — years of salt damage, stained carpets, or heavily soiled seats — this is what a deep clean service is for.
Step 6: Wax, Sealant, or Ceramic Top-Up for Spring/Summer Protection
With the paint clean, decontaminated, and corrected, now is the right time to apply fresh protection before spring UV exposure and warmer temperatures kick in.
What to use depends on what’s already on the car:
- Coated car: Apply a ceramic top-up spray (Gyeon Wetcoat, for example) after washing to restore hydrophobics. You don’t need a new full coating unless it’s failing.
- Uncoated car: Apply a good carnauba wax or synthetic sealant. Bilt Hamber Dodo Juice Hard Wax offers a couple of months of protection. If you want longer-lasting protection, a gloss enhancement service with professional sealant or coating lasts 6-12 months.
- Want proper long-term protection: Spring is a good time to get a ceramic coating. You’ll get full benefit across summer driving.
UV is a genuine threat to unprotected paint. Prolonged direct sun exposure oxidises clear coat and dulls the finish permanently. Protecting the paint in spring prevents the worst of the summer UV damage.
Step 7: Rubber and Trim Restoration
Rubber seals, exterior trim, and interior plastic all dry out over winter. Cold temperatures, road salt, and months with no treatment leave them looking faded and feeling brittle.
What to do:
- Treat exterior rubber seals around doors and boot with a rubber conditioner (Autoglym Rubber Care works well). This prevents cracking and keeps the seals effective.
- Exterior trim (black plastic bumpers, mirror housings, unpainted sills): treat with a product like Autoglym Bumper Care or Gyeon Trim. Faded trim can often be significantly restored.
- Interior trim and rubber floor mats: clean with a diluted all-purpose cleaner, then condition with a trim dressing. Not the high-gloss silicone type — use a matte or satin finish that doesn’t make interior plastics look greasy.
This step makes a big visual difference for minimal effort. Restored trim makes a car look 3-4 years younger.
Step 8: Windscreen and Wiper Check
Your wipers have been working hard all winter. Smearing, squeaking, or streaking are signs they need replacing. Most wiper blades last 12-18 months, and winter is the hardest season for them.
What to do:
- Inspect wiper blades for cracking or deformation. Run them with water and see how cleanly they clear the screen.
- Clean the windscreen properly with a dedicated glass cleaner — IPA wipe first to remove silicone contamination, then glass polish if there’s significant haze or wiper smear.
- Treat the windscreen with a hydrophobic coating (Rain-X or similar) for improved visibility in wet conditions through spring.
Also check the washer fluid and replenish with a proper screenwash at the right concentration for the remaining cold nights.
The Teesside-Specific Angle
A few things that make post-winter care more important here than in other parts of the UK:
Road salt from the A66 and A19 — These are heavily gritted routes all winter. If you commute on either, you’re getting more salt exposure than most UK drivers.
Coastal salt air — If you’re in Redcar, Saltburn, or anywhere near the coast, salt’s in the air year-round. Winter amplifies it. The combination of road salt and sea salt is particularly aggressive on paint and underbody.
Industrial fallout — Teesside’s industrial sites mean there’s more airborne contamination than in a typical town. It’s less than it was, but it’s still present. Iron fallout decontamination matters more here than in, say, rural Yorkshire.
I cover this in more detail in the North East paint protection guide.
Do It Yourself or Book a Professional?
Most of the washing, decontamination, and rubber treatment you can do at home with the right products. The stages that benefit most from professional work:
- Paint correction (gloss enhancement or correction): You need a machine polisher and experience to do this properly. Hand polishing doesn’t generate consistent results.
- Interior deep clean: A genuine deep clean — hot water extraction on carpets, proper seat cleaning — needs professional equipment.
- Ceramic coating: Surface prep and application quality determines how long the coating lasts. Not a DIY job if you want it to last.
If your car went through a rough winter and you want to set it up properly for spring, book a deep clean or get in touch on WhatsApp to discuss what combination of services makes sense for your car’s condition.
