For areas like carpets and seats, I use industrial fans and dehumidifiers to expedite the drying process. I’ll often remove the seats and carpets entirely if the damage is severe to ensure everything gets dried properly.

Once the interior is dry, I inspect for any mold or mildew, which can be a health hazard and cause long-term damage. If I find any, I use specialized cleaning solutions to eliminate it. Finally, I check the electronic components and wiring, as water can cause serious issues there. If any components are compromised, I either repair or replace them to ensure everything is functioning correctly before returning the vehicle to the customer. This thorough process ensures the vehicle is safe and comfortable for the owner.”
