Although you may not be able to answer this question yourself off the top of your head, you've certainly seen the symbol for delicates before. On the labels of most garments there are washing instructions, which usually show a washtub. If this tub is highlighted on the bottom with two horizontal lines, you are dealing with delicates. Simple!
Delicate laundry includes clothes with very finely made fabrics that require special care, such as dress pants, especially when it comes to washing, drying and picking a laundry detergent for delicates. This applies, for example, to silk, some types of wool, nylon fabrics or underwear. Garments that shrink quickly are considered delicates and therefore need a little more attention.
