Seatbelts are a high-contact area that’s easy to overlook during interior detailing—but they can trap sweat, skin oils, food stains, and odors that affect your vehicle’s cleanliness and smell. Whether you’re detailing for resale or deep-cleaning your own car, knowing how to clean seat belts properly helps preserve both the appearance and function of this safety system.
Here’s the best way to clean car seatbelts like a pro:
Step-by-Step: How to Clean Seatbelts
- Pull out and secure the seatbelt:
Extend the belt fully and clip it with a clamp or locking clip to prevent it from retracting during cleaning. In most cases, full removal isn’t necessary unless heavy extractor or steamer use is planned. - Vacuum first:
Remove any loose debris or pet hair using a handheld vacuum or interior crevice tool. - Pre-treat stains:
Spray the belt with a diluted all-purpose cleaner like Magic Cleaner Concentrate or targeted stain remover like Hot Shot. Let it dwell for 30–60 seconds. - Agitate gently:
Use a soft or medium-duty bristle interior detailing brush to loosen embedded grime without fraying the fabric. Avoid aggressive scrubbing or wire brushes. - Wipe clean:
Use a clean, damp microfiber towel to wipe away the product and loosened dirt. Use edgeless microfiber towels to prevent snagging. - Repeat or escalate as needed:
For heavy-duty cases, consider steam or extractor use (see below). - Dry properly:
Allow the belt to dry fully while extended. Do not retract while wet. You can hang it, use clips, or set a fan to speed up drying.
How to Steam Clean a Seatbelt
Using a vapor steamer is a safe, chemical-free way to deep clean car seat belts without oversaturating the fabric.
Tips for steam cleaning seatbelts:
- Use a triangle attachment with a microfiber bonnet, or a nylon bristle attachment
- Hold the wand 1–2 inches away to avoid fiber damage
- Gently wipe with a microfiber towel as you steam

Cleaning Seatbelts with a Carpet Extractor
For stained, greasy, or heavily used belts, a carpet extractor provides powerful cleaning and extraction.
Steps:
- Pre-treat with APC or enzyme cleaner
- Gently agitate with a soft brush
- Extract with a hand tool attachment—use minimal moisture
- Blot dry with microfiber
- Hang to dry in an extended position

Final Tips for Seatbelt Cleaning & Maintenance
