Whether you're getting ready to sell your car, prepping for a road trip, or just want a fresh, clean ride, giving your vehicle a car deep clean can make a huge difference. Many people vacuum and wipe surfaces, but a true deep clean goes further. From seats to hidden corners, this guide covers how to deep clean a car interior properly.

1. How to Deep Clean Car Seats
Seats are one of the most-used parts of your car and often hold onto dirt, stains, and odors. The steps to deep clean car seats vary depending on the material.
Fabric CarSeats
- Vacuum first to remove dust, crumbs, and pet hair.
- Use a fabric/upholstery cleaner or make a DIY mix of water, vinegar, and dish soap.
- Spray lightly, scrub with a soft brush, and blot with a clean towel.
- Let seats air dry with windows cracked open.
Leather Seats
- Wipe down with a damp microfiber cloth to remove surface dust.
- Apply a leather cleaner or conditioner using a soft cloth.
- Buff gently to lift dirt and protect the material from drying out.
Tip: Avoid using too much liquid, especially on fabric seats, to prevent mold and lingering smells.
2. Cleaning the Floor and Carpets
The floors see a lot of wear from shoes, spills, and road grime. A good car deep clean includes getting into these areas.
Floor Mats
- Remove and shake out mats to get rid of loose dirt.
- For rubber mats: Scrub with soap and water, then rinse and air dry.
- For carpet mats: Vacuum, spot clean with carpet cleaner, and let them dry fully before putting them back.
Carpet Areas
- Vacuum thoroughly, including under seats and along edges.
- Use a carpet shampoo or foam cleaner to tackle stains.
- Work in small sections and blot up moisture with clean towels.
3. Don’t Forget the Nooks and Crannies
The little spaces in your car collect more dirt and dust than you realize. If you're wondering how to deep clean a car interior completely, this is where it counts.
Air Vents
- Use a soft detailing brush or cotton swab to reach between the slats.
- Spray with compressed air to blow out dust.
Cup Holders & Storage Compartments
- Remove inserts if possible, wash separately.
- Use an all-purpose cleaner and a cloth to wipe down inside.
- For tight spots, a toothbrush or foam brush works well.
Door Panels, Dash, and Steering Wheel
- Wipe down all surfaces with a damp microfiber cloth.
- Use a plastic or vinyl protectant to prevent fading or cracking.
Under Seats and Between Cushions
- Slide seats forward and back to reach hidden debris.
- Use a crevice tool on your vacuum for narrow gaps.
