The Wash Guide

New · Out now on iPhone, iPad and Mac

The Wash Guide is on iPhone.

The dose for the bottle you own, a temperature you can stand behind, and any care label read back in plain words. On iPhone, iPad, Mac and Android, with one household shared across them all.

The evening’s first question, ‘What’s going in the drum?’, answered for coloured cotton T-shirts

In brief

Straight answers about the things nobody agrees on.

Written carefully, sourced where sources exist, and free.

What are you holding?

Ask about the garment in your hands.

A symbol you cannot read, a fabric you are not sure about, a load you do not know how often to run. One field, and it searches everything here.

9 pieces, 45 symbols and the whole schedule. Nothing behind a sign-up.

The label says

How often to wash everything.

The answer first, then the argument. Honest intervals for the things nobody agrees on, and why the scary numbers are usually wrong.

The Recipe

Exactly how much detergent to use.

For a full drum of everyday cotton, not very dirty, in a 7 kg machine. Change the two things that move the number most, then take it to your own load.

Your water
Your detergent

70 ml

About 2.4 fl oz.

At 40°C.A warm wash, 104°F. Softener if you like it.

We’ve adjusted this for a full drum and hard water. You said you’re not sure about your water, so we’ve assumed it’s hard. Most packs don’t ask for more than this, so the dose stops here.

Now for the load in front of you

Everything we’ve written, sorted by subject rather than by date. Each chapter grows as we write.

  1. The WhyThe wash is the smallest part of looking after clothes. What you do in the days between decides how often you need one.The founding piece · 5 minA shirt hung over the back of a chair with jeans and a folded tee on the seat, blind-light striping the wall behind
  2. How OftenHonest intervals for the things nobody agrees on: sheets, towels, jeans, gym clothes and the rest. Knowing the number is the easy part.6 pieces, and the scheduleWashing hung on a line across a sunlit plaster facade, between two shuttered windows
  3. The Cold MonthsOften, yes, and sometimes more safely than by hand. Wool shrinks when it is rubbed, not when it gets wet, and a good wool cycle rubs it less than a sink does.One piece · 7 minThree folded jumpers stacked on a pale wooden stool against a plain wall: a cream one with navy stripes on top, then olive, then a speckled yellow knit
  4. StainsIt is not your sweat, which is almost certainly clear. It is the antiperspirant, working on your shirt instead of on your skin.One piece · 6 minA man in a cream linen shirt leaning against a plaster wall in a bright room, one sleeve rolled
