I try n keep back of my van tidy so it doesnt need cleaning regular or anything. Yep agree on the cab section, when i cant see my seats anymore than its time to tidy
Outside of van, i pick my kids up from school. They finish at half 3 but to get parked up you have to be there at 3. So if vans dirty, i whip out the brush n give it a once over.
Just waiting for other parents to ask so i can charge em to clean their cars
