Cleaning exterior is easy compared to interior,
So I drive most of the time closing windows rolled up switching on AC inside city to avoid dust of Metro and fly-over constructions. Interiors we have many places which goes unnoticed and few places are difficult to reach and clean without a air blower or vacuum cleaner.
Maintaining a Black car is not difficult its impossible usually washing car takes 1-2Hrs but the effort even wont last long for an 1hrs after wash, take a short drive and car looks like its wasn't washed for weeks
