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. Continue until all water is absorbed, ensuring the area under the driver's side floor mat is thoroughly dried. Visit a repair shop to use high-pressure air to blow through the pipes and clear any blockages. It is recommended to have the drain pipes under the front windshield checked and cleaned regularly at a repair shop. It might be caused by a leak in a certain part of the car body. Locate the leaking area and repair it. There are many drainage channels or holes in various parts of the car body.

I often deal with this issue because I forget to close the windows on rainy days, and water flows in. First, use an old towel to vigorously absorb the water, being careful not to let it seep into the electronic wiring. After absorbing, completely remove the floor mats and lay them in a ventilated area to dry or use a hair dryer on low heat. Remember to check if the door seals are damaged or if the drainage holes are blocked, otherwise, water will accumulate again during the next heavy rain. When parking, choose a higher spot to reduce water entering the door sill channel, and regularly clean under the floor mats to prevent dust from clogging the drainage holes. Paying attention to these small details will keep you free from water troubles.

This situation needs to be addressed immediately. Prolonged water accumulation under the floor mats can cause rust on the car frame and even short-circuit the electrical system, which is very dangerous. I recommend using a vacuum cleaner with a water suction function to extract the water, or slowly absorb it with towels. Then remove all the floor mats and place them under the sun to dry and dehumidify. Check the air conditioning drain pipe or window leakage points and repair them to prevent recurrence. For safety, don't just simply blow-dry and put them back; ensure the area under the mats is completely dry and odor-free before reinstalling them for peace of mind.

Don't panic when you find the floor mats damp underneath. I usually use household towels to quickly absorb the moisture. If the towels can't absorb any more, I take out the mats, flip them over, and let them air dry for a day. Remember, the source is often gaps in the car doors or air conditioning leaks, so it's best to plug those up. After simple ventilation, place some dehumidifying bags underneath to prevent mold and avoid repeating this hassle during the next humid weather.
