Laundry Instructions: What Works and What to Avoid

You see laundry instructions on your clothes care labels. There are symbols, words, and warnings. You’re not sure what they all mean or which ones matter. Laundry instructions tell you how to wash, dry, bleach, and iron each garment. Following them keeps your clothes looking new and prevents damage. Ignoring them can ruin clothes. Here’s what works and what to avoid when it comes to laundry instructions.

Laundry instructions are directions on care labels that tell you how to wash, dry, bleach, and iron a garment. Laundry instructions use both symbols and words. The symbols are standardized internationally and use shapes to represent different care operations. Following laundry instructions prevents shrinking, fading, melting, and other damage.

To follow laundry instructions, read the care label before washing, learn the 5 basic symbols (tub, triangle, square, iron, circle), follow the water temperature and cycle recommendations, use the right detergent and bleach, and dry as directed. Don’t ignore the instructions, don’t use hotter water than recommended, and don’t tear off care labels.

Sort by Care Requirements

Sort clothes not just by color but also by care requirements. Don’t wash hot-water items with cold-water items.

What to Avoid

Ignoring the Instructions

Ignoring laundry instructions can ruin clothes. Washing wool in hot water shrinks it. Drying synthetics on high heat melts them. Ironing silk on high heat scorches it.

Using Hotter Water Than Recommended

Using hotter water than the label recommends can shrink, fade, or damage clothes. Always follow the temperature on the label.

Using the Wrong Dryer Setting

Using high heat on low-heat clothes causes shrinking and melting. Using the dryer on no-dryer clothes damages the fabric.

Using the Wrong Bleach

Using chlorine bleach on oxygen-bleach-only clothes strips color. Using bleach on no-bleach clothes damages the fabric.

Tearing Off Care Labels

Tearing off care labels means you can’t check the instructions later. Leave care labels on clothes.

Not Sorting by Care Requirements

Mixing clothes with different care requirements means some clothes get washed in the wrong settings.

Using Too Much Detergent

Excess detergent leaves residue on clothes and in the machine. Use 2 tablespoons per load.

Using Fabric Softener

Fabric softener coats fibers and can damage some fabrics. Use vinegar instead.
