The former chief minister of Delhi chose BR Camp, a low income area, on the very day PM Modi launched his Clean India campaign.
Mr Kejriwal was accompanied by several employees of the civic agency, and he later had tea with them, an Aam Aadmi Party spokesman said.
The BR Camp falls in Kejriwal's New Delhi assembly constituency.
"AAP will launch a cleanliness drive Oct 2," an AAP tweet said. "All MLAs and leaders will work as helpers to Safai Karmcharis (cleaning staff) and help them in their work."
