Before anything else, always check the care label and follow the specific washing instructions for each piece.
As a general rule, a gentle hand wash is often the safest method. Fill a clean sink or basin with lukewarm water and add a small amount of mild detergent. Submerge your accessories and let them soak for around 15 minutes.
Use your fingers to gently work any areas that need extra attention, then rinse thoroughly with clean water to remove all soap residue.
Avoid twisting or wringing out the fabric, it can stretch or distort the shape. Instead, lay each piece flat on a clean towel, reshape carefully, and allow to air dry away from direct sunlight, which can cause fading.
