According to Groves, officers rushed the hat to Hartford Cleaners. Meanwhile, employees at Douglas Jewelers worked to restore a metal pin that's part of the cap.
The hat was eventually handed over to The Brass Rooster in Milwaukee to be restored.
John McLaughlin and his wife, who own The Brass Rooster, spent more than 10 hours working on the cap.
"It involved cleaning, steaming, re-blocking, conditioning the leather, putting a dressing on it," McLaughlin said. "Hopefully it's now as good, or better, than before it was taken."
All of the businesses that assisted in cleaning and restoring the hat did so for free. They, along with members of Scherger's family, gathered at the police department Wednesday morning to officially place the cap back into its display case.
Scherger's grand-nephew Ronald Kadolph first donated the cap to the city in 2013 when a community room at City Hall was remodeled and named in the Marshal's honor.
"I feel like it belongs to them more than to me now, because of all the trouble they went through retrieving it and fixing it up," Kadolph said.
The suspect in the cap theft is 31-year old Scott Moen. The police chief said he was hit with several municipal citations of almost $700 each.
City officials are also requesting that Moen pay $6-thousand to $7-thousand in restitution for the costs the Washington County Dive Team and the Water Treatment Plant spent in searching for the hat.
