Go to a car wash shop, take out the floor mats, and use a vacuum cleaner to remove most of the water. Use dry towels alternately placed under the floor mats to absorb water until clean. Go to a repair shop and use high-pressure air to blow through the pipes.

Last time, water suddenly appeared on the floorboard of my car, possibly due to the window not being properly closed after heavy rain or a leaking air conditioning pipe. I immediately used dry towels to vigorously soak up the water, then opened the windows to let hot air blow in to speed up drying, which took quite a while. Water accumulation on the floorboard can easily lead to rust or mold, damaging the car's structure. Later, I learned my lesson and now regularly check the door seals and air conditioning drain holes to prevent small issues from turning into major repairs. I also specifically added a floor mat to absorb water, making it easier to clean. Remember, don't let water sit for too long, otherwise it can corrode the electrical circuits, which would be troublesome.

As a parent who often takes kids out, finding water on the car floor makes me nervous, worrying about kids slipping or bacteria growth. I first quickly absorb the moisture using a household vacuum or cloth to dry it, then lift the carpet to trace the source, like aging sunroof seals or chassis holes. Usually, I park away from rain and clear debris to prevent leaks. Spending time on these measures extends the car's lifespan, saving hassle, money, and ensuring safety.

Hey, I've encountered this issue before. Water on the floorboard mostly comes from AC condensation or umbrella drips. I simply wipe it clean with a damp cloth, open the windows for ventilation, and ensure the drainage pipes are clear. Basic maintenance like this prevents rust effectively—saves money and keeps the car running smoothly.
