Upholstery cleaning can be required when the car seats are dirty, something has been spilled or if an odor source needs to be removed.
With upholstery cleaning, hot water is used in combination with a chemical that dissolves dirt. We use a special washer that sprays chemical liquid while it sucks up the dirty water. This makes the dirt disappear by washing through the fabric. Then upholstery is dried with a dehumidifier after being washed. The process is repeated until the result is perfect.
If there is a bad smell in the car, the treatment should be combined with a subsequent odor removal.
