Gov. Andrew Cuomo was hands on during a tour Saturday of the coronavirus subway car cleaning operation at a MTA maintenance facility in Queens — taking a stab at blasting the bug himself with a spray of disinfectant.

“Do you guys need a hand?” Cuomo asked as he walked onto a subway car, while five workers in hazmat suits were abuzz with activity around him, video released by the governor’s office shows.

“We’re good,” one replied.

Undeterred, Cuomo grabbed a hose, squatted down and began spraying disinfectant  underneath a train seat.

“God bless you. Thank you so much for doing this guys. Thank you,” Cuomo told the workers.

 The cleanings, from 1 a.m. to 5 a.m., will begin Wednesday with no planned end-date. Bleach and other disinfectants will be used.

“They have to go through the train with a misting device and spray disinfectant literally on every surface,” Cuomo said later at a briefing from the Flushing maintenance yard.

He continued: “There are reports that say the virus can live two or three days on some surfaces like stainless steel. You look at the inside of a subway car, you look at the rails, the bars, they’re all stainless steel.”
