Step-by-Step Instructions
Step 1: Prepare the Washing Area
Fill a clean sink or basin with cold water. Ensure the area is free from any contaminants that could transfer to your sweater.

Step 3: Submerge the Sweater
Gently submerge your wool sweater into the water, ensuring it is fully saturated. Do not wring or twist the fabric.
