When washing in a top-loader with liquid detergent, you should first fill with water, then add soap, then add clothes, right? Well, no. This protocol from the past was meant to prevent residue on the fabric and the machine. But modern detergents are phosphate-free and not harmful to clothes the way old formulas were. As long as you're not using bleach, don't add clothing after the water (a pain, because clothes can float). Instead, use this order to distribute detergent best: clothes, then water, then soap.
Mistake 4: Washing an Item That Has a "Dry-Clean" Label
This isn't necessarily a blunder. Most items that say "dry-clean" can be hand washed and air-dried. This includes natural fibers, such as linen and most silks. First check for colorfastness; moisten a cotton swab with mild detergent and dab it on a hidden seam to see if any dye comes off. If not, go ahead and dunk the garment in soapy water just once or twice, then rinse and immediately roll it in a towel to extract moisture. However, you should stick with dry-cleaning for certain categories: leather, suede, silk dupioni, anything with embellishments, and structured pieces (like blazers).
