Using a steam cleaner on your car seats is indeed an efficient and eco-friendly method that effectively dissolves stubborn stains and sanitizes surfaces.
You can use a high-powered car vacuum cleaner and a brush to clean the dust on the surface of the roof, then spray a neutral foam cleaner on the velvet surface of the inner ceiling, wait a few minutes, then use a wet towel to clean and dry it. This can effectively clean the interior roof of the car. Choose the appropriate cleaner according to the color and material of the interior roof.
