A JFK Airport employee has been arrested after two children were accidentally burned when a bottle of Drano dripped all over them on a Queens bus Saturday, cops said.

The two brothers, ages 5 and 8, suffered mild acidic burns around 5:30 p.m. in Forest Hills when police believe a bottle of Drano “ate through” a man’s back pack and dripped onto the three passengers.

The children are in stable condition, cops said.

Ivan Ivanov, 32, was charged with reckless endangerment after taking the drain cleaner home in an unsafe container, police said.

Cops do not believe the act was intentional.
