Sort your laundry before washing—this is the first step of a good laundry routine. You probably know to sort your clothes by what color they are but, ideally, you’d sort your clothes by fabric, too. A quick look at the care label will tell you what the garment is made of. Silk is best washed separately from cotton, as the two textiles need very different treatments in the washing machine. The laundry detergents needed for cotton and silk are also different—cotton can handle powerful detergents such as Persil® Odor Fighter, while silk needs a gentler detergent and often needs to be dry cleaned.
Once you’ve sorted each pile by material, sort each pile of laundry again, but by color this time. Red socks in white laundry are a cliché, but unless you really want pink clothes, you’d be well advised to sort your clothes as best you can!
