How do you dry out a car after a water leak?
Reviewed by the Skyview Auto Glass technical team — NWRD-, ASE- and DINITROL-trained technicians · Updated November 2026
Quick answer
Stop the leak first, then lift the edge of the carpet, wet-vacuum the standing water, and run airflow and a dehumidifier in the cabin until the padding beneath the carpet is dry. Check the padding, not just the carpet surface, because it holds water long after the top feels dry. A musty smell means it is still wet.
How to dry a wet car interior
Work in order: stop the water, remove what you can, then dry what remains, finishing with the padding beneath the carpet.
- 1
Stop the leak
Find and fix the source before drying, or the carpet will be wet again after the next rain. A water test locates a glass leak, and the fix is a reseal or a reinstallation.
- 2
Soak up the standing water
Use a wet vacuum to pull the water out of the carpet. Towels press the rest out of the fibers, but a wet vac reaches deeper.
- 3
Lift the carpet edge
Pull the carpet away from the sill plate at the door so air can reach the jute padding underneath, where most of the water hides.
- 4
Run airflow and a dehumidifier
Point fans across the open carpet and run a dehumidifier in the closed cabin. Leave the doors and windows shut so the dehumidifier pulls the moisture down rather than fighting outside air. The padding dries slowly, so give it time and check it by hand.

Check the padding
Press the padding with your hand. If it feels damp or smells musty, it is not dry yet. Keep the airflow going until it is.
What to have ready
- A wet vacuum to pull standing water out of the carpet.
- Towels to press the remaining moisture out of the fibers.
- A fan or two to move air across the open carpet.
- A dehumidifier to pull moisture out of the closed cabin.
- A way to prop the carpet edge away from the padding so air reaches it.
The padding holds the water
The carpet surface can feel dry while the jute padding underneath is still soaked, and that is what causes a musty smell. Lift the carpet edge and check the padding by hand before you decide the interior is dry.
More questions about drying a car
How do I get moisture out of my car?
Soak up standing water with a wet vac, lift the carpet edge so air reaches the padding, and run fans and a dehumidifier in the closed cabin. Check the padding by hand, since it dries slower than the carpet surface.
How do I stop a musty smell after a leak?
Dry the padding fully, not just the carpet surface, because trapped moisture is what causes the smell. If the smell persists after drying, the padding may need replacing, which is an upholstery job Skyview does not do.
How long does it take to dry a wet car carpet?
It depends on how much water got in and how well air reaches the padding. The surface dries in hours, but the padding underneath can take a day or more with airflow and a dehumidifier.
