Cleaning your sweater depends on the material it's made from. Here's a general guide for different types of sweaters:

1. **Wool or Cashmere Sweaters**

   - **Hand Wash**:

     - Fill a basin with cold water and add a small amount of wool or cashmere detergent.

     - Gently submerge the sweater, swirl it around without stretching or wringing it.

     - Let it soak for about 5–10 minutes.

     - Rinse with cold water until soap is gone.

   - **Drying**:

     - Roll the sweater in a towel to remove excess water (never wring it out).

     - Lay it flat on a clean, dry towel or drying rack to air dry.

     - Avoid direct sunlight or heat, which can shrink or damage fibers

2. **Cotton Sweaters**

   - **Machine Wash**:

     - Use the gentle cycle on cold with mild detergent.

     - Place the sweater inside a mesh laundry bag to protect it from stretching or snagging.

   - **Drying**:

     - Lay flat to air dry. Machine drying can cause cotton to shrink or lose its shape.

3. **Acrylic or Synthetic Sweaters**

   - **Machine Wash**:

     - Wash in cold water on the gentle cycle.

     - Use a mild detergent, and avoid fabric softener to prevent fiber buildup.

   - **Drying**:

     - Most acrylics are safe to machine dry on low heat, but to be cautious, lay flat to dry.

 4. **Delicate Sweaters (Angora, Mohair, etc.)**

   - **Hand Wash**:

     - Use cold water and mild detergent designed for delicates.

     - Gently swirl and rinse.

   - **Drying**:

     - Gently press out water with a towel, and lay flat to dry.

General Tips:

   - **Avoid Hang Drying**: Hanging sweaters can stretch them out of shape. Always lay them flat to dry.

   - **Pilling**: Use a sweater comb or fabric shaver to remove pills.

   - **Storage**: Fold sweaters rather than hanging them to avoid stretching. Store wool or cashmere in breathable bags to prevent moths.Let me know if your sweater has specific care instructions on its label!
