Golden rules of how to wash any type of school jumper  

Choose the right setting

Always opt for the delicate setting. The gentle touch ensures that the intricate knitwork of the jumper is treated with the care it deserves.

Short wash cycles

Select the shortest cycle available. This minimises the exposure to friction, preserving the jumper's softness and preventing any potential damage.

Check the care label

Before tossing your jumper into the wash, consult the fabric care label to ensure it's washer safe. Following manufacturer guidelines helps maintain the garment's integrity. If you’re unsure, all our product pages include the individual care instructions for each item.

Separate wisely

Keep your knitwear separate from heavier fabrics like denim to prevent unnecessary wear and tear during the wash.

Turn inside out

To combat pilling, turn the jumper inside out before washing. Button up all buttons and close zips to further protect the fabric.

Optimal drying

If using a dryer, choose the lowest heat setting. For best results, lay the garment flat to air dry. Avoid hanging wool or knitted items, as this can cause fibres to stretch.

Avoid fabric softener

Fabric softener can weaken fibres and damage garments. Yes, they make your clothes soft and smell nice. But is it worth it?!
