5 Interior Detailing Mistakes Every Driver Makes (and How to Avoid Them)

When it comes to keeping your car clean, most people think about the paint, wheels, or exterior shine. But the reality is you spend most of your time inside the cabin — and that’s where interior detailing matters most. A clean interior doesn’t just look better; it makes driving more enjoyable and helps preserve your car’s value.

The problem? Many drivers unknowingly make the same interior detailing mistakes over and over again. These slip-ups can leave streaks, damage surfaces, or make your car look dirtier than before.

At Blackline Car Care, we’ve seen it all. Here are 5 common interior detailing mistakes every driver makes and how to fix them.

1. Spraying Interior Cleaner Directly on Surfaces

Spraying product straight onto your dashboard or screen might feel efficient, but it causes overspray. Liquid seeps into vents, seams, or electronics, which can lead to stains or even long-term damage.

Fix it: Always spray your interior cleaner onto a microfiber towel or brush first, then wipe. This gives you more control and prevents oversaturation.

2. Using Household Towels Instead of Microfiber

Old rags, T-shirts, or paper towels might be convenient, but they aren’t safe for car interiors. They push dirt around instead of trapping it, and they can scratch delicate surfaces like touchscreens or glossy plastics.

Fix it: Use dedicated microfiber towels for interiors. They grab dust and oils effectively and leave surfaces clean and streak-free.

3. Overusing Product

More product doesn’t mean a cleaner car. Over-applying protectants or sprays leaves behind streaks, residue, or a greasy finish that actually attracts more dust.

Fix it: Use 1–2 sprays per section and work in small areas. Buff off excess with a dry microfiber towel for a natural, OEM finish.

4. Ignoring Hidden Areas

Most people wipe down the dash and steering wheel, but dirt hides in cup holders, vents, and between seats. Skipping these areas leaves your car feeling “half-clean.”

Fix it: Use small brushes for vents, a vacuum for crevices, and a damp microfiber for cup holders. The details make the biggest difference.

5. Choosing Harsh or Shiny Cleaners

Some cleaners leave dashboards shiny and slick. While it might look good in photos, it feels greasy in person and can even cause dangerous windshield glare. Harsh chemicals can also dry out vinyl or leather.

Fix it: Stick with pH-balanced interior cleaners that leave surfaces looking natural, not glossy. The goal is to restore the “factory finish,” not make your dash shine like plastic.
