3 Commonly Missed Spots In An Exterior Detail (And How To Nail Them Every Time)
Even experienced detailers can miss a few key areas when doing an exterior detail. These aren't necessarily difficult to clean—but because they’re less obvious or harder to reach, they often get overlooked. Here's how to give your clients that “wow, they really got everything” experience.
1. Gas Lid Area – The Hidden Trap
Why it's missed:
Because the gas door is usually closed when the wash begins, it’s easy to forget. Out of sight, out of mind.
Why it's important:
The gas lid area collects road grime, fuel residue, and dust that can build up over time. It’s one of those “surprise” areas a client might check—especially if they’re meticulous.
How to do it right:
Always open the gas door before you begin rinsing or foaming the car.
Use a dedicated soft detail brush and an all-purpose cleaner (APC) to scrub the inside and edges. The APC might not be needed depending on the condition of the gas lid area & the strength of the soap you are using.
Rinse thoroughly but avoid blasting water into the fuel nozzle area.
Wipe dry with a microfiber drying towel to prevent water spotting or corrosion.
Pro Tip: A touch of dressing on the plastic cap tether or hinge area can give that extra clean look.
2. Emblems & Grills – Dirt Magnets in Disguise
Why they're missed:
They’re usually “hit” during a general wash but rarely get the focused attention they need. These areas have tight crevices where brushes and mitts don't always reach.
Why they're important:
Emblems and grills are front and center. If there’s any lingering dirt, bugs, or soap residue stuck in there, it immediately takes away from the overall finish of the detail.
How to do it right:
Pre-treat with a bug and tar remover to break down buildup. Don’t let it dry in the sunlight as it can be bad for the paint.
Use soft detailing brushes to get inside every letter, edge, and vent.
For grills, a variety of tools—such as a mini wheel brush or even foam-tipped swabs—can make a big difference.
Rinse thoroughly and inspect with good lighting.
Dry with compressed air or a microfiber drying towel tucked into the crevices to avoid water streaks or drips later.
Pro Tip: Apply a light coat of sealant or wax around emblems to make future cleaning easier.
3. Door Jambs – The Most Forgotten “Exterior” Area
Why they're missed:
Some detailers consider this part of the interior detail, or skip it entirely. But clients see this spot every single time they get in or out of the car.
Why it matters:
Nothing breaks the illusion of a clean car faster than opening a door and seeing grime or pooled water. It signals a rushed or incomplete job.
How to do it right:
Before you foam or rinse the exterior, open each door and inspect the jambs.
Use a degreaser or APC and a soft brush to agitate grime, especially near hinges and rubber seals.
Rinse carefully, avoiding overspray into the interior of the vehicle.
Dry thoroughly with microfiber drying towel and/or compressed air to prevent streaks or water pooling.
If time allows, finish with a spray sealant or quick detailer for that smooth, protected feel.
Pro Tip: Ask for the keys early in the job so you can do this step properly and revisit after final drying for touch-ups.
