Four Australian men who stripped down and soaped up at a car wash have been charged with exposure and public nuisance.

Police said two 19-year-olds and two 23-year-olds paid for a full-service wash and then stripped nude and washed themselves in the soapy water while their female companions took photos.

Police arrived after being called by Smart Wash operators. The four were given notices to appear in court next month.

Police and the car wash operator warned the public after the incident: "Do not try this at your local car wash."

"The high pressure washer could be quite dangerous, especially if it goes in the eyes," Senior Sergeant Nick Paton of Biloela police said.

"It could take somebody's eye out."
