Washing your dog's bedding in the washing machine should not contaminate the unit for subsequent loads of laundry if you follow some basic guidelines:
Remove Excess Hair: Before washing your dog's bedding, shake it out or remove excess hair to minimize the amount of loose fur in the washing machine. You can also use a lint roller or brush to remove any remaining hair.
Pre-Wash or Rinse: If the bedding is heavily soiled or covered in mud, consider giving it a quick rinse or pre-wash cycle to remove the majority of the dirt and debris before placing it in the washing machine. This step can help prevent excessive dirt or debris from getting into the machine.
Use Hot Water and Appropriate Detergent: Wash the bedding using hot water and an appropriate detergent. Hot water helps kill any potential bacteria or parasites that may be present in the bedding. Make sure to follow the detergent manufacturer's instructions for proper usage.
Clean the Washing Machine Regularly: To maintain the cleanliness of your washing machine, it's a good practice to periodically clean it. Run an empty cycle with hot water and a cleaning agent specifically designed for washing machines. This helps remove any lingering pet hair, odors, or bacteria that may have accumulated over time.
By following these guidelines, you can minimize the chances of contaminating subsequent loads of laundry. However, if you're concerned about potential cross-contamination or have specific health concerns, you can also wash your dog's bedding separately from your regular laundry or use a washing machine with a sanitize cycle option to ensure thorough cleaning and disinfection.
