15 May The Right Way to Separate Laundry: Colours, Fabrics, and Dirt Levels

Doing laundry might not be the most exciting task, but getting it right can save your clothes from fading, shrinking, or getting ruined altogether. If you’ve ever ended up with pink-stained whites or a misshapen jumper, chances are you didn’t sort your laundry correctly. The good news? It’s easy to avoid these common mistakes once you know how to sort laundry properly.

In this guide, we’ll walk you through the right way to separate your washing—by colour, fabric type, and dirt level—so every load comes out fresh, clean, and damage-free. A little prep goes a long way, and once you get into the habit, it becomes second nature.

Why You Need to Learn How to Sort Laundry Properly

Sorting your laundry might seem like an extra step, but skipping it often leads to ruined clothes and wasted time. When you throw everything into the machine together, you risk colour bleeding, fabric damage, and uneven cleaning. That favourite white T-shirt turning grey or your wool jumper shrinking? It likely happened because the wash wasn’t sorted correctly.

Learning how to sort laundry properly helps you avoid these problems and extend the life of your clothes. Your whites stay crisp, your darks keep their richness, and your delicate items retain their shape. Plus, by grouping laundry based on fabric type and dirt level, you improve washing efficiency and use less energy.

Proper sorting also means your clothes get the wash they need. Tough stains don’t transfer to lightly worn items, and delicate fabrics don’t get stretched or torn in the wrong cycle. Ultimately, sorting saves money, protects your wardrobe, and makes laundry day far less frustrating.

How to Sort Laundry Properly

✅ Sort by Colour First

When figuring out how to sort laundry properly, colour is the most important place to start. Mixing darks with whites or brights with pastels often leads to disaster—think pink-stained socks or dull, grey T-shirts. To keep your clothes looking their best, always separate your laundry into distinct colour groups.

Here’s a simple breakdown to follow:

• Whites – This includes white shirts, socks, underwear, towels, and bed linen. Wash these separately to keep them bright and avoid discolouration.

• Lights – Group soft shades like pale blue, pink, beige, and light grey. These can usually be washed together safely.

• Darks – Keep dark shades such as black, navy, deep reds, and forest greens in one load. These colours are the most likely to bleed, especially in warm washes.

• Brights – Vivid colours like bright red, orange, purple, or emerald green should be washed on their own—at least for the first few washes—so they don’t transfer dye to other items.

Even clothes that seem colourfast can release dye when exposed to heat or agitation. If you’re ever unsure, test by wetting a hidden area and pressing it with a white cloth. If the colour transfers, wash it separately.

By taking a few extra moments to sort by colour, you’ll preserve the vibrancy of your clothing and avoid unexpected laundry disasters. It’s one of the easiest yet most effective ways to master how to sort laundry properly.

✅ Then, Separate by Fabric Type

Once you’ve grouped your clothes by colour, move on to fabric. Thick towels and lightweight blouses should never share the same cycle. Consider separating into:

• Heavy fabrics – Towels, jeans, hoodies.

• Delicates – Lingerie, silk, lace, and light knitwear.

• Everyday clothing – T-shirts, blouses, cotton pyjamas.

Mixing different materials can lead to damage. For instance, rough towels may cause pilling on soft fabrics, and heavier items take longer to dry, wasting energy.

If you want to truly master how to sort laundry properly, always check the care labels. Some fabrics require cold washes or special detergent, so don’t ignore the small print.

✅ Finally, Sort by Dirt Level

Once you’ve separated clothes by colour and fabric, there’s one last step to get the cleanest results: sort by how dirty each item is. This might seem like overkill, but it’s a crucial part of properly sorting laundry. Why? Because mixing heavily soiled clothes with lightly worn ones spreads dirt and bacteria, and often means nothing comes out truly clean.

To sort by dirt level, divide your laundry into three groups:

• Lightly soiled – These are items you’ve worn once or twice without sweating or staining them. Think pyjamas, casual tops, or office wear. A short cycle and cooler water usually do the trick here.

• Moderately soiled—Clothes with visible signs of wear, such as sweat patches, light food marks, or dust, fall into this category. Jeans, gym tops, and school uniforms often fit this category.

• Heavily soiled – Muddy trousers, tea towels, sports kits, and anything with strong odours or stubborn stains need a more powerful wash. Use a longer cycle, higher temperature (if the fabric allows), and perhaps a stain remover.

Washing these groups separately not only improves cleaning results but also protects your lighter-wear garments from over-washing. Plus, you’ll avoid re-depositing grime onto cleaner items—something that often happens when dirt levels are mixed.

Understanding how to sort laundry properly by dirt level means fewer rewashes, better hygiene, and longer-lasting clothes. It’s a small habit that pays off with every load.

Bonus Tips to Help You Sort Like a Pro

Now that you know how to sort laundry properly, take it a step further with a few clever tricks that make the job even easier. These habits save time, prevent common laundry issues, and keep your clothes in top condition.

• Use divided laundry baskets – Invest in a laundry hamper with separate sections for whites, colours, and darks. This way, your sorting is done as you go.
• Check care labels before washing – Always glance at the label to avoid mixing items that need different temperatures or cycles. Some clothes may look similar but require totally different care.
• Turn garments inside out – This protects prints, embroidery, and delicate surfaces from fading or friction damage in the wash.
• Close zips and hooks – Fasten any buttons, zips, or bra clasps to prevent them from catching on other items.
• Use mesh laundry bags – Put delicates like underwear, baby socks, or lace items into mesh bags to stop them getting lost or damaged.
• Pre-treat stains straight away – The longer you wait, the harder they are to remove. Treat stains before adding the item to your laundry pile.
• Keep a small bag for odd socks – When you find a single sock, pop it in a designated bag until the other one turns up. No more lonely socks hiding in the corner of your wardrobe!

When you pair smart habits with proper sorting, laundry day becomes far less frustrating—and your clothes stay fresher, brighter, and cleaner for longer.

Final Thoughts on How to Sort Laundry Properly

Learning how to sort laundry properly isn’t just about avoiding laundry mishaps—it’s about protecting your clothes, saving time, and getting better results every single wash. By taking a few extra minutes to separate garments by colour, fabric, and dirt level, you prevent fading, shrinking, and cross-contamination between items.

Once you build the habit, sorting becomes second nature. Combined with smart laundry habits—like using mesh bags, checking labels, and pre-treating stains—you’ll find that your wardrobe lasts longer, looks better, and smells fresher.

So next time you’re tempted to toss everything in together, remember: a little effort before the wash saves a lot of trouble after.
