A Taupo Quay window washer appeared in Whanganui District Court on Tuesday for assault after he squirted cleaning liquid in a man's eyes.
Joshua Thomas Robinson was cleaning car windscreens at the intersection of Taupo Quay and Victoria Ave on February 7 when one motorist did not want their window cleaned.
Robinson poured detergent on the windscreen although the victim told him not to, said police prosecutor Sergeant Stephen Butler.
The victim, a passenger in the car driven by his wife, asked Robinson to stop several times before trying to open the door and having Robinson push the door back at him.
The victim asked him to go away but Robinson pushed his bottle at him and squirted detergent into his eyes.
