Start with care labels
Special-care items should be identified before they enter a general load.
Separate by practical risk
Color, fabric weight, lint transfer and soil level may matter depending on the items.
Avoid rigid rules
Modern fabrics and machines vary, so garment and appliance instructions are more useful than one universal sorting chart.
Check pockets and fasteners
A quick pre-wash check can prevent small objects from damaging garments or equipment.
