Your whistle should not need any serious care but we would recommend occasional cleaning in luke warm water. A small amount of anti-bacterial washing detergent may help.
If the whistle has an internal deposit of white substance this will be calcium that has precipitated from saliva. A pipe cleaner and water and vinegar (very weak) will help but this is stubborn and may need scraping with a pin or nail file.
