Demystifying Fabric Care Labels

We've all done it. You pull a favourite shirt out of the wash and it's now three sizes smaller, or your white linen looks like it went through a spin cycle in a coffee cup. The culprit? Those tiny fabric care label icons you've been ignoring ... or guessing at.
Care labels aren't just there to itch the back of your neck. They're your garment's instruction manual, and once you know how to read them, you'll save money, clothes, and a whole lot of frustration.
In South Africa, clothing follows the international ISO care labelling system (ISO 3758), so whether your label came off a local boutique find or an imported brand, the same icons apply. Let's break them down.
Big Five: What Those Tiny Icons Actually Mean
Most labels follow a standard order: Wash, Bleach, Dry, Iron, and Dry Cleaning.
The Washtub (Washing)
The Triangle (Bleaching)
The Square (Drying)
The Iron (Ironing)
The Circle (Dry Clean)
1. The Washing Symbols
The washing symbol looks like a small basin or bucket of water. Dots inside the basin indicate temperature, and lines underneath tell you how gentle the wash should be.
🔵Temperature: What the Dots Mean
Symbol | Meaning | What to wash here |
 | Cold / cool wash (30°C) | Delicates, dark colours, synthetics |
 | Warm wash (50°C) | Most everyday clothing, cotton blends |
 | Hot wash (50°C) | Heavily soiled cottons |
 | Very hot wash (60°C) | Whites, towels, bedding - kills germs |
 | Extremely hot (70°C) | Rarely used; very robust fabrics only |
 | Boil wash (95°C) | Medical textiles or heavily stained whites |
A good rule of thumb: when in doubt, go cooler. Hot water is harder on fabric fibres and causes more shrinkage and colour fading. South Africa's warm climate also means cold washes are more eco-friendly - your machine doesn't have to heat the water as much.
🟰Cycle Type: What the Lines Underneath Mean
Symbol | Meaning |
 | Normal cycle - full spin, full agitation |
 | Permanent press / synthetics - gentler spin |
 | Very gentle cycle - for delicates like wool or silk |
💧Hand Wash vs. Do Not Wash
Hand wash symbol (basin with a hand): Fill a basin with cool or lukewarm water. Gently squeeze the item through — don't twist or wring. Rinse thoroughly.
Do not wash symbol (basin with a cross through it): This item cannot be wet-cleaned at all. It will need dry cleaning or spot cleaning only.
2. The Bleaching Symbols
Bleach symbols look like a triangle. This is one of the most important symbols to get right - use bleach on the wrong fabric and you'll end up with holes, discolouration, or a ruined garment.
Symbol | Meaning |
 | Any bleach is safe to use |
 | Only use oxygen-based (colour-safe) bleach - not chlorine bleach |
 | Do not bleach under any circumstances |
For most South African households, it's safest to default to colour-safe bleach unless the empty triangle is clearly visible. Chlorine bleach (like Jik) is powerful but unforgiving on anything except pure white cotton.
3. The Tumble-Drying Symbols
Tumble dryer symbols look like a square with a circle inside. Dots inside the circle indicate the heat level, just like with washing.
Symbol | Meaning |
 | Low heat — for delicates and synthetics |
 | Medium heat — most everyday fabrics |
 | High heat — robust cottons and linens |
 | Permanent press cycle — medium heat, cool-down |
 | Gentle/delicate cycle — low heat and slow tumble |
 | Do not tumble dry — air dry only |
Good news for South Africans: our sunshine does most of the work for free. Line drying is almost always better for your clothes than tumble drying — lower energy costs, less fabric wear, and that outdoor-fresh smell you can't buy in a bottle.
4. Natural Drying Symbols
These symbols tell you how to dry without a machine. They look like a square with different lines or shapes inside.
Symbol | Meaning |
 | Line dry / hang to dry |
 | Drip dry — hang while wet, let water drain naturally |
 | Dry flat — lay it on a towel to keep its shape |
 | Dry in the shade — sunlight may fade this fabric |
"Dry flat" is especially important for wool knitwear and chunky jerseys. If you hang them while wet, gravity pulls the fabric down and you end up with stretched-out shoulders and a garment that's lost its shape permanently.
5. The Ironing Symbols
Ironing symbols look exactly like a small iron. The dots inside tell you how hot your iron should be.
Symbol | Meaning | Best for |
 | Low heat (110°C) | Synthetics like polyester, nylon, acrylic |
 | Medium heat (150°C) | Wool, silk, polyester blends |
 | High heat (200°C) | Cotton and linen |
 | Do not iron | Heat-sensitive fabrics or embellishments |
 | No steam | Iron dry — steam may cause water marks or damage |
If you're ever unsure, start with a low setting and work up. You can always add more heat, but you can't unmelt a synthetic fabric.
6. The Dry-Cleaning Symbols
Dry cleaning symbols look like a circle. Letters inside the circle tell the professional dry cleaner which solvents to use. As a home user, you just need to know whether dry cleaning is required or not.
Symbol | Meaning |
 | Dry clean only — take it to a professional |
 | Do not dry clean |
 | Standard dry cleaning — most common |
 | Dry clean with specific solvents — tell your dry cleaner |
 | Professional wet cleaning — specialist only |
When a label says "dry clean only", it usually means the fabric is too delicate for water, or the construction of the garment (padding, lining, embellishments) can't survive a wash. It's worth the cost to get it done properly rather than ruining a special piece.
Examples of Fabric Care Labels on Common South African Fabrics
Cotton
Usually, machine washable at 40°C or 60°C.
Can be tumble dried on medium heat.
Iron on high heat.
Bleach allowed unless specified otherwise.
Wool
Often hand wash or machine wash on wool cycle at 30°C.
Do not tumble dry; lay flat to dry.
Iron on low heat with a cloth between iron and fabric.
Polyester
Machine washable at 30°C or 40°C.
Tumble dry on low heat.
Iron on low heat.
Avoid bleach.
Silk
Hand wash or dry clean.
Do not tumble dry.
Iron on low heat with a cloth.
How to Handle Clothes Without Labels
Sometimes, clothes bought from markets or second-hand stores may not have care labels. In such cases:
Test a small hidden area with water and detergent.
Use cold water and gentle detergent.
Air dry to avoid shrinkage.
When in doubt, hand wash.
Quick Tips for South African Laundry
Hard water is common in many parts of SA. Use a good detergent and consider a water softener to prevent mineral buildup on your clothes.
Our strong UV sunlight bleaches colours over time. Turn dark or coloured clothing inside out when line drying, and follow the "dry in shade" symbol where indicated.
During load-shedding, hand washing and line drying become your best friends. Learn those symbols and you'll be prepared no matter the schedule.
When sorting laundry, check every label before throwing items into the same wash. One wool jersey in a hot cotton cycle is all it takes for disaster.
Care labels exist to help your clothes last longer ... and they work, when you pay attention to them. A little knowledge goes a long way, and once these symbols become second nature, you'll wonder how you ever loaded the washing machine without them.
