How to Separate Laundry the Right Way

6 min read

Separating laundry seems simple, but there's genuine confusion about what actually needs to be separated and when you can bend the rules. Here's a straightforward guide.

Quick Answer

Sort laundry into at least three piles: darks, lights, and colors. Always separate brand new items, true whites, and heavily soiled clothes. With cold water and well-washed items, you can often combine darks and midtone colors safely.

The Basic Categories

At minimum, separate your laundry into these groups:

1. Darks

Black, navy, dark brown, dark gray, dark purple, dark green. Anything that could potentially bleed dye onto lighter items.

2. Lights

White, cream, beige, light gray, pastels. Anything that could be discolored by darker items.

3. Colors (midtones)

Red, orange, bright blue, green, yellow. Vibrant colors that might bleed but aren't light enough to be stained by darks.

Do You Really Need to Separate?

The honest answer: It depends on what you're washing.

Always separate:

  • Brand new dark or brightly colored items (they bleed the most on first washes)
  • True whites that you want to keep bright
  • Heavily soiled items from lightly soiled items
  • Items with specific care requirements (delicates, dry-clean-safe, etc.)

You can often combine:

  • Older, well-washed darks and midtones together
  • Colorfast items (clothes that have been washed many times without bleeding)
  • Light colors and whites (if you're not using bleach)

The cold water factor: Washing in cold water significantly reduces color bleeding. If you wash everything in cold, you have more flexibility with combining loads.

Beyond Color: Other Ways to Sort

By fabric weight:

Heavy items like jeans and towels can damage delicate fabrics in the wash. They also take longer to dry. Consider separating:

  • Heavyweight (jeans, sweatshirts, towels)
  • Lightweight (t-shirts, underwear, dress shirts)
  • Delicates (lingerie, silk, anything with lace or embellishments)

By soil level:

Heavily soiled items (muddy kids' clothes, grease-stained work uniforms) need more aggressive washing. Putting them with lightly soiled items means everything gets beaten up more than necessary.

By care requirements:

Check labels. Items marked "gentle cycle" or "wash separately" should be respected.

The Practical Approach

If you're doing laundry at a laundromat, here's a realistic sorting system that balances results with efficiency:

  • Pile 1: Darks (cold water, normal cycle) — All your jeans, black shirts, dark colors.
  • Pile 2: Lights and whites (warm water, normal cycle) — White and light-colored everyday clothes.
  • Pile 3: Towels and sheets (hot water, heavy cycle) — These can handle and benefit from hot water.
  • Pile 4 (if needed): Delicates (cold water, gentle cycle) — Anything fragile or labeled for special care.

At The Wash House, you can run all these loads simultaneously using different machines, then dry them on appropriate heat settings.

Special Cases

Red items: New red fabrics are notorious for bleeding. Wash new red items alone for the first 2-3 washes, or with other reds and dark colors only.

New jeans: Dark denim bleeds significantly. Wash new jeans inside-out, alone or with similar darks, in cold water.

Lint producers vs. lint attractors: Towels and fleece produce lint. Dark dress clothes and synthetic fabrics attract lint. Washing them together means your black work pants come out covered in fuzz.

Zippers and hooks: These can snag delicate items. Either separate them, or close all zippers and hooks before washing.

The Pre-Laundromat Prep

Sorting at home before you leave makes your laundromat visit smoother:

  1. Sort into separate bags or baskets
  2. Turn appropriate items inside-out (jeans, printed shirts)
  3. Check all pockets
  4. Close zippers and hooks
  5. Pre-treat any visible stains

When you arrive, you can load machines immediately without spending time sorting in the laundromat.

Frequently Asked Questions

Can I wash darks and colors together?

If they're not brand new and you're using cold water, usually yes. The risk is lower with older, well-washed items that have already released most of their excess dye.

Do I need to separate by fabric type?

It's helpful but not always necessary. The main concern is delicates getting damaged by heavy items like jeans, or lint transfer between certain fabrics like towels and synthetic clothes.

What happens if I wash everything together?

With cold water and well-washed clothes, probably nothing bad. With new items, hot water, or mixing whites with darks, you risk color transfer and dulling of whites.

Should I wash new clothes before wearing them?

Yes, and wash them separately. New clothes often have excess dye, chemicals from manufacturing, and sizing that can transfer to other items or irritate skin.

Can I wash towels with regular clothes?

It's best to wash towels separately. They produce lint that sticks to other fabrics, they benefit from hot water that could damage regular clothes, and they're heavier which can cause uneven washing.

How do I prevent colors from bleeding in the wash?

Use cold water, wash new items separately for the first few washes, turn dark items inside out, and consider adding 1/2 cup white vinegar to the rinse cycle to help set dyes.

What's the best way to sort laundry for a family?

Create four main piles: darks (cold water), lights and whites (warm water), towels and sheets (hot water), and delicates (cold, gentle cycle). This balances efficiency with protecting your clothes.

Run Multiple Loads at Once

At The Wash House, you can sort into as many piles as you need and wash them all simultaneously.
