How to Deal with Wet Car Floor?
4 Answers
If there is water accumulation on the floor mats, remove the rubber mats and dry or clean them. Quickly wipe away any water on the floor with a cloth as soon as possible. Spray car-specific foam cleaner onto any fabric surfaces and gently wipe with a cloth. Open the car doors and windows to allow the moisture to dry completely. Check if the sunroof is leaking; prolonged exposure to sun and rain can cause aging.
I remember last year during the rainy season, the floor of my car suddenly got wet, with water soaking through the footwell area. I immediately used old towels to absorb the water vigorously, using about four or five until it was mostly dry. Then, I parked the car in the garage, opened all the doors, and used a household electric fan to blow air inside for an entire night to ensure it was thoroughly dried. Later, I discovered that the door’s lower seal strip had aged and cracked, allowing rainwater to seep in. I went and bought a new seal strip and replaced it myself. Since then, I’ve made it a habit to check the seals every time after washing the car, and I regularly clean the sunroof drainage holes to prevent clogging. Lingering moisture can easily lead to mold growth, which is bad for the cabin air quality—especially for families with children, it’s crucial to address it promptly to avoid triggering respiratory issues.
The most common reason for a wet car floor is water leakage, such as clogged sunroof drain tubes, damaged door waterproof membranes, or backflow of condensation from the air conditioning system. When dealing with it, don't rush to start the car. First, use a thick towel to repeatedly press and absorb the surface moisture, then use a hairdryer or heat gun on the low-temperature setting to slowly dry the carpet underneath. A wet vacuum cleaner is even better. Identifying the source is key. You can test it yourself by splashing some water outside the car to see where it leaks in. For prevention, regularly clean the drainage holes under the doors to prevent leaves and dirt from accumulating. If the sealing strips are aging, you can easily buy replacement parts online and change them yourself, saving money and ensuring peace of mind.
A wet floor is a big issue—not only is the dampness uncomfortable, but over time, the carpet can rot and mold, breeding bacteria that harm health. It may also corrode internal wiring, posing a short-circuit risk. Stop immediately to ensure safety. If possible, use a dry cloth or vacuum to remove surface water, then ventilate and dry thoroughly. Place dehumidifiers to absorb residual moisture. Develop a habit of checking the car's seals and drainage system before and after rainy days, and clear blockages promptly. Simple actions prevent major troubles.
