How to Do Laundry

Sorting, water temperature, detergent amount, and drying — without ruining anything.

Quick Start

The short version. The details, tips, and FAQ are below.

  1. Sort: keep new darks and brights away from whites, and heavy items apart from delicates.
  2. Empty every pocket and close the zippers.
  3. Use cold water for most loads. Go warm or hot only if the care label allows it.
  4. Pour detergent up to the cap's line for your load size. More doesn't clean better.
  5. Pick the cycle for the most delicate item in the load.
  6. Dry the way the care label says. When unsure, use low heat or air-dry.

The Quick Start above covers a normal load. Below is the reason behind each step, how to read care labels, and what to do when something goes wrong.

Step by Step

  1. Sort. Wash anything new and dark or brightly colored away from whites and light colors for its first few washes — that’s when dye is most likely to run. After that, sorting by fabric weight (delicates vs. towels and jeans) matters more than sorting by color.
  2. Empty pockets and close zippers. A forgotten pen or tissue can ruin a whole load, and open zippers snag other clothes.
  3. Choose the water temperature. Cold works for most everyday loads and is gentler on colors. Warm or hot is better for towels, bedding and very dirty items — if the care label allows it.
  4. Add detergent. Use the line on the cap or the amount on the package for your load size. More detergent doesn’t clean better, and too much leaves a residue.
  5. Pick the cycle for the most delicate item in the load. If one thing needs “delicate,” the whole load gets “delicate.”
  6. Dry by the care label. Some fabrics shrink or lose their shape on high heat. When unsure, use low heat or hang it to dry.

Tip: Don’t overload the machine. Clothes need room to move for the water and detergent to reach them — a drum should be no more than about three-quarters full.

Reading Care Label Symbols

  • A tub is washing; dots inside it show the temperature (more dots = hotter). A hand in the tub means hand wash only.
  • A triangle is bleach. An empty triangle means any bleach; one with diagonal lines means non-chlorine bleach only.
  • A square with a circle is tumble drying; the dots show the heat.
  • An iron is ironing, again with dots for heat.
  • A circle on its own is dry cleaning.
  • An X through any symbol means don’t. An X through the tub means don’t wash it in water at all.

When a care label disagrees with what you’d normally do, trust the label — it’s specific to that garment.

If a Color Already Bled onto Something

Rewash the item right away, before it goes anywhere near the dryer — heat can set the dye permanently. A color-catcher sheet or a little extra detergent in that rewash can help lift it. For a stain that has already dried, a color-run remover can help, though it doesn’t always work fully.

Common Mistakes

  • Washing a new dark item with lights before it has been washed once on its own.
  • Overloading the washer or the dryer.
  • Drying something on high heat that the label says to air-dry.
  • Leaving wet clothes in the washer for hours, which makes them smell musty.

Frequently Asked Questions

Do I really need to sort my laundry?

At minimum, separate anything new and dark/brightly colored from your whites and light colors for the first few washes — that's when dye is most likely to bleed. After that, sorting by color matters less than sorting by fabric weight and care label (delicates vs. heavy items like towels and jeans).

How much detergent should I actually use?

Follow the line markings on the cap or the amount printed on the packaging, based on load size — more detergent doesn't mean cleaner clothes, and too much can leave residue or even attract more dirt. Most detergent caps are marked for small/medium/large loads.

What do the little symbols on clothing tags mean?

They're standardized care instructions: a tub icon is the wash setting (dots inside indicate temperature), a triangle is bleach instructions, a square is drying, and an iron shape is ironing instructions. An X through any symbol means don't do that. When a care label conflicts with your instinct, trust the label.

A color already bled onto something — can I fix it?

Rewash the affected item right away, before it goes in the dryer — heat can set the stain permanently. A color-catcher sheet or a bit of extra detergent in that rewash can help lift the dye. A dedicated color-run remover product can help for a stain that's already dried and set, though it isn't always fully reversible.

Should I wash new clothes before wearing them?

Generally yes, especially anything with strong dye or a noticeable odor from packaging — it reduces skin irritation and gets rid of loose dye before it has a chance to transfer during that first wear.

What if I don't have access to a dryer?

Air-drying works for most fabrics, and some care labels require it — just plan for more time and more flat or hanging space than a dryer needs, especially for anything heavy like towels or jeans.
