"I put food on my f****** family's table."
"I'll f****** kill you," he later threatens.
Police told 3News one of the window washers was aged 17. He was charged with common assault, assault on a police officer and resisting arrest.
The other washer was 15. He was charged with disorderly behaviour and would likely be referred to Youth Aid.
Mr Chong said he took the video off YouTube after being threatened by a family member of one of the two young men. However, the video had been reposted by other *YouTube account-holders. (*Language warning)
Mr Chong said he would not be laying any additional charges over the incident.
"The guys are in enough grief as it is, and they can't afford anything.
"The video that's out there - all I want to do is make sure is that people know that we don't need window washers."
The aggressive nature of some window washers "ruined it for everyone", Mr Chong said.
The council already had a by-law in place which ruled that people could not solicit business on a road, and another which stated people were not allowed to linger on a road, however they were rarely enforced, he said.
A statement on the council's website advised New Plymouth residents not to pay window washers.
The council received three to four complaints a week about the behaviour of the washers at intersections, and more washers were "cropping up" over summer, the statement said.
