Berrise Lovelock said the pressure cleaners were economical.

"It does use less water," he said.

He said the washing should only occur during the two-hour periods allocated on Sundays when residents can water their plants, trees and gardens.

"What difference is it spending half an hour watering your garden or spending it on your caravan?" he said.

Mr Lovelock said he would normally use a trigger hose to wash his van but that was banned under the restrictions.

He said his van was too big to go through a carwash.

Mr Lovelock said it could go through a truckwash but the nearest was in Blayney.

He said he had cleaned his caravan with a broom but that did not get the top cleaned or remove as much grime as a high-pressure cleaner would achieve.

Mr Lovelock said he supported a call by Orange City councillor Glenn Taylor to allow residents to wash their cars with high pressure cleaners.

He said that should also include caravans.

Cr Taylor asked council staff for a report on using the high pressure cleaners at the last council meeting.

Mr Lovelock said owners were keen to clean their caravans now as many would be preparing for a journey.

"It seems to be a nice time to travel from now on," he said.

"You don't go in the real heat of summer.

"We've got friends with vans and they do similar trips."

Mr Lovelock said he was a retired panel beater who had used tank water at his business in Borenore and had used high-pressure cleaners.

The use of high-pressure cleaners on vehicles is allowed in Dubbo which is on Level 4 restrictions.

The vehicles need to be on the lawn to be washed.

They can also be washed with a bucket and rinsed clean with a trigger hose.

Vehicles can also be washed at home in Mudgee which is under Level 2 water restrictions. The Mid-Western Regional Council allows washing with a bucket and rinsing with a trigger hose on the lawn between 9am-noon any day.

However, vehicle washing at home is banned in Bathurst.
