A:Answer Hello BG!
Thank you for your inquiry.
The Sanitary Cycle for the LG - TurboWash 4.3 Cu. Ft. 12-Cycle High-Efficiency Steam Front-Loading Washer, Model # WM3570HVA is a cycle for Heavily soiled underwear, work clothes, diapers, etc., that uses an extra-hot wash Temperature to reduce Laundry Bacteria. NSF International (formerly the National Sanitation Foundation), certifies that this wash cycle reduces 99.9% of bacteria on laundry through high temperature, when used with powdered detergent.
The washer also has an Allergiene™ cycle which is a powerful, high temperature cycle designed specifically to reduce certain allergens. Selecting the Allergiene™ cycle automatically incorporates steam into the wash cycle. The Allergiene™ cycle can significantly reduce allergens in bedding and clothing. The Allergiene™ cycle helps reduce dust mite populations and helps reduce allergens.
Due to the higher energy and temperatures used, the Allergiene™ cycle is not recommended for wool, silk, leather, or any other delicate or temperature sensitive Items...IFV
