It may be easy to throw a load of mixed laundry into the machine, but if you don’t want everything to turn an odd shade of pink or grey, it's best to learn how to separate laundry . If you only have a small amount from one group, then don’t be tempted to put it in with another. Save it for a full load.
Use a partitioned laundry basket – it’ll save you time sorting it all out later.
In case someone in your household places something in the wrong section, check the garments' labels for the manufacturer’s washing recommendations.
If in doubt, test an item for colorfastness by applying warm water to an inconspicuous part (for instance, the inside of a hem), then press with a warm iron between two pieces of cloth. If any color leaks, it’s not colorfast.
