"Home minister today (Saturday) instructed the Delhi CP (B.S.) Bassi to ensure that all police stations and other complexes are cleaned within a week," a tweet from the home ministry said.
Rajnath Singh has also asked Bassi to monitor the cleanliness drive in police buildings.
"The home minister may undertake a surprise visit to any police station or other building after a week or so," another tweet said.
Prime Minister Narendra Modi Oct 2 launched the Swachh Bharat Abhiyan, a nation-wide cleanliness drive that seeks to clean up the country in five years.
Modi had also paid a surprise visit to the Mandir Marg police station in central Delhi, on his way to Valmiki Colony to launch the campaign, to check how clean it was - and wielded a broom on finding its environs dirty.
