How should I actually use this soap bar for laundry or stain removal?

This solid bar is designed for direct application. For pre-treating stains or washing smaller items by hand, the typical method is to moisten the fabric and the soap bar. Then, gently work the wet bar directly onto the stained area, such as collars, cuffs, or underarms, until you create a rich lather.

Let the soap sit on the fabric for a few minutes to allow it to work on the grime. Afterwards, you can either rinse the treated item thoroughly by hand or place it in your washing machine for a regular cycle. This method provides targeted cleaning exactly where needed and is often more convenient than trying to pour liquid detergent onto a small spot.

For general hand-washing of fabrics, you can lather the bar between your hands or rub it directly on the wet textile, then agitate the item in the water to distribute the suds. After washing, rinse the soap bar, let it dry, and store it in a dry place to prevent it from becoming soft or mushy.
