Understanding the 3 compartments in a Bosch washing machine drawer

A Bosch washing machine drawer typically features three distinct compartments, each designated for specific types of laundry products:

1. Compartment I (Prewash): This compartment is labeled with a "1" or "I" and is used for detergent intended for the prewash cycle. This cycle is optional and is ideal for heavily soiled items, allowing an initial wash before the main cycle begins
   
2. Compartment II (Main Wash): Marked with a "2" or "II", this compartment is designated for the main wash detergent. It is where you place the primary detergent used during the main washing cycle
3. Compartment III (Fabric Softener): The middle compartment, often symbolized by a flower icon, is used for liquid fabric softener. This product is added during the rinse phase of the washing process to soften fabrics and reduce static cling.
