TL;DR

Reading the Care Label

Every piece of clothing has a care label, usually sewn into the seam or collar. It contains symbols that tell you exactly how to wash, dry, and iron the item. Most people ignore these until something shrinks or gets ruined. Don't be that person.

The five most important symbols:

When in doubt on anything delicate or unfamiliar, cold water and air drying is almost always the safe choice.

Sorting Before You Wash

Sorting takes two minutes and prevents most laundry disasters. The two things that matter most:

New item trick

Before washing a new dark or brightly colored item for the first time, soak it in cold water with a tablespoon of white vinegar for 30 minutes. This helps set the dye and reduces how much it bleeds in future washes.

Washing

For the vast majority of everyday laundry, cold water works fine and is gentler on fabric and color. Hot water is useful for bedding, towels, and anything that needs to be sanitized, but it shrinks and fades clothing faster.

Detergent

Use the amount specified on the detergent bottle, which is usually less than you think. More detergent does not mean cleaner clothes. It leaves residue on fabric and can irritate skin. Liquid detergent dissolves better in cold water than powder. For delicates, use a detergent labeled for delicate or gentle wash.

Cycle selection

Drying

The dryer causes more clothing damage than the washer. Heat shrinks fabric, breaks down elastic, and fades color over time. A few rules that make clothing last significantly longer:

On shrinking

If something cotton has already shrunk in the dryer, soak it in warm water with a tablespoon of hair conditioner for 30 minutes, then gently stretch it back to shape while wet and lay flat to dry. It won't always recover fully, but it often helps.

Common Stains

The most important rule with stains: treat them immediately. A fresh stain is far easier to remove than one that has dried and set. Blot, don't rub. Rubbing spreads the stain and pushes it deeper into the fabric.

For anything you're unsure about, test your stain treatment on a hidden area of the fabric first before applying it to the visible stain.

Things Worth Knowing

Ironing and Steaming

A clothes steamer is faster and easier than an iron for most situations, and harder to damage fabric with. Worth the $30 to $50 if you wear anything that wrinkles. Run it over fabric while it's hanging and wrinkles fall out in seconds.

For ironing when you need sharper results:
