More than two tonnes of dust has been washed off the track at Barden Park, Dubbo Regional Council's (DRC) Athletic Centre of Excellence.
The man who was in charge of the exercise said it was the most debris he could recall ever being removed from a track.
"Drought red dust contributions from Broken Hill to Narromine had filled up of the rubber granulated surface with fine red dust which was exactly the same colour as the track," said Sports Clean founder Peter Luffman.
"This compacted dust would have been compromising the tracks performance.
"The volume of red dust was a great test for Sports Clean's new WashMatic machine recently imported from Germany."
The council's director of liveability Skye Price said it was important to have the most ideal surfaces when attracting events to the region.
She said the track had not had a "major deep clean" since being built in 2014.
"With some significant events coming up this year it was important for DRC to conduct these rejuvenation works," Ms Price said.
The council reports further repairs to the facility will be done throughout the year.
The Barden Park Athletics Centre of Excellence, located on Gipps Street, is home to the Dubbo Athletics Club.
More than 25 school athletics carnivals are held at the facility annually which has played host to major events such as the NSW Little Athletics State Multi Event and Athletics NSW Country Championships.
