Laundry symbols can be a mystery to many of us, but they're actually quite straightforward once you know what they mean.
The symbol "P" on a care label indicates that the item should be hand washed or dry cleaned.
Don't be fooled by the "P" symbol, it's not a suggestion, it's a requirement.
If you ignore the "P" symbol and try to machine wash a delicate item, you risk damaging it beyond repair.
Laundry symbols are designed to protect your clothes and ensure they last as long as possible.

In the USA, a textile labeling law dictates the specific order in which the five key care symbols must appear, ensuring consumers can easily interpret them.
The five key care symbols are Washing, Bleaching, Drying, Ironing, and Dry Cleaning. Understanding how to read these symbols is essential for properly caring for your clothes.
A black triangle with an X inside is an obsolete symbol and means that bleaching is not allowed. This is a warning to avoid using bleach on a particular garment.
The dots in the tub determine the temperature of the water. The more dots in the bath, the higher the water temperature.
Here's a guide to the water temperature symbols:
- Cold water: Clothes with a single dot should be washed in cold water between 65°F and 85°F.
- Warm water: Clothing with two dots should be washed in warm water with a maximum temperature of 105°F.
- Hot water: Clothing with three, four, or five dots should be washed in hot water with a maximum temperature of 120°F, 140°F, or 160°F, respectively.
Understanding the clothes washing symbols can give you an idea of the temperature and wash cycle to use. The number of dots in the tub of water symbol indicates the temperature.
Here's a list of the wash symbols:
- Machine Wash: Safe to wash in a machine using the temperature and cycle indicated by other symbols.
- Hand Wash: Do not wash in a machine, wash by hand.
- Do Not Wash: Do not wash in a machine or tub, take to a professional dry cleaner.
- Dry Clean Only: Take to a dry cleaner for removal of dirt or other stains.
- Do Not Dry Clean: Wash using the gentlest setting on your washer.
The square shapes tell you what drying method, drying temperature, and drying cycle to use. This will help your clothes retain their shape and size.
For example, if a label instructs you to tumble dry, it means you should use heat and a specific cycle setting. If it says don't tumble dry, you should hang the garment to dry or dry it flat.

Bleaching
Bleaching is a common concern when it comes to laundry care labels. An empty triangle or a triangle with a square in it means that bleaching is allowed. This is a straightforward indication that you can use bleach on the garment.
If you see a crossed-out triangle, it's a clear warning that the garment must not be bleached. This is especially important because chlorine or oxygen bleach can damage the fabric. I've seen this happen to a friend's favorite sweater, and it was a real bummer.
A triangle with CL in the center means that the laundry may only be bleached with chlorine bleach. This is a specific instruction, so make sure you use the right type of bleach to avoid damaging the garment.
Domestic bleaches come in two types: Peroxide and chlorine. Peroxide bleaches are usually gentle and contain hydrogen peroxide or sodium percarbonate. They're often labeled as "active oxygen" and are commonly used in stain removers like Vanish and OxiClean.
Here's a quick rundown of what the different symbols mean:
- Empty triangle: Bleaching allowed (with any type of bleach)
- Triangle with CL: Bleaching allowed with chlorine bleach only
- Crossed-out triangle: Bleaching not allowed
Drying
The drying process can be just as crucial as washing, and using the wrong settings can damage your clothes. Tumble drying is allowed for garments with the Tumble Drying Allowed symbol, but be sure to check for additional symbols indicating heat settings or potential damage.
A standard Tumble Dryer symbol with an "X" through it means the garment should not be put into the dryer at all. Instead, hang it on a clothesline or drying rack to dry. You could also put these garments through an extra spin cycle to remove excess water before hanging.
Items with the Hang to Dry symbol should be put on a line to air dry, ideally in a shady area out of direct sunlight to prevent heat damage. A square with a curved line at the top indicates that an item should be hung on a clothesline to dry.
The dry flat symbol, featuring a horizontal line in the middle of the square, means the clothing should be laid out to dry on a flat surface. This method is usually recommended for delicate fabrics such as wool, knitwear, or fine silk.

Ironing
Ironing can be a bit tricky, but understanding the symbols on your clothes can make all the difference. The ironing symbols on clothing labels tell you how to iron and at what temperature it's safe to do so.
If you see a plain iron symbol, it means you can iron your pieces, and the lowest setting is recommended for delicate fabrics. An ironing symbol with a dot in the middle indicates that you should iron at a low temperature, usually for fabrics like silk or acrylics.
Two dots in the ironing symbol mean you should iron at a medium temperature, suitable for fabrics like polyester or wool. Three dots in the symbol mean you should iron at a high temperature, suitable for durable fabrics like cotton or linen.
A crossed-out ironing symbol means you shouldn't iron the item, as it may damage your textiles. Ironing at high temperatures can damage delicate fabrics, so it's essential to follow the recommended temperature.
Here's a quick reference guide to ironing symbols:
By understanding these symbols, you can avoid damaging your clothes and keep them looking their best.
Dry Cleaning
Dry cleaning can be a bit of a mystery, but understanding the symbols on your clothes can make all the difference. A circle with a P means professional dry-clean with any solvent except trichloroethylene.

These symbols are designed to be clear to dry cleaners, but not always to the layperson. The International Association for Textile Care Labelling-Care Symbols, GINETEX, has established a set of standards for care labelling code using symbols.
If you see a crossed-out circle, it means the item should not be dry cleaned at all, and you should avoid using any solvent-based stain removers. The revised Canadian standard and Swedish care symbols also include this symbol.
Professional dry cleaning in hydrocarbons uses special, solvent-based solutions that are flammable but gentler than perchloroethylene. Domestic solvent-based stain removers should not be used on these items.
Here are some common care symbols and their meanings:
- P - Professional cleaning required: A circle with a P means professional dry-clean with any solvent except trichloroethylene.
- F - Liquid cleaning required: The symbol "F" indicates that the garment should be cleaned only with petroleum-based solvents.
- A - All Solvents: The symbol “A” means that you can use any solvents to clean the fabric.
- W - Wet clean: The symbol with the circle and "W" in it stands for "Wet Clean".
- Do not dry clean: A crossed-out circle means the item should not be dry cleaned at all.
Labels and Symbols
Laundry symbols can be confusing, but understanding them can make a big difference in keeping your clothes looking their best. The FTC suggests that manufacturers provide additional information so consumers can understand the care label, especially if only symbols are used.
A circle by itself usually means dry cleaning or wet cleaning, while a circle inside a square indicates tumble dry. Adding lines, dots, and other marks to these base symbols adds more information, such as a large X through a symbol negating it or offering a warning.

Understanding laundry symbols can help you care for your clothes properly, prevent damage, and keep them looking their best.
Deciphering Laundry Symbols
The ironing symbols on care labels are the most intuitive, but they can be a bit confusing if you don't know what they mean. The iron pictogram can be enhanced with one to three dots, indicating the maximum heat, as well as symbols depicting the use of steam.
A circle by itself usually means dry cleaning or wet cleaning, while a circle inside a square changes "dry" to "tumble dry." Adding lines, dots, and other marks to these base symbols adds more information.

A large X through a symbol negates it or offers a warning, whereas an empty symbol often means that any version of what the symbol represents is OK to use. For example, a standard triangle signifies bleaching is OK on that garment, while a crossed-out triangle means "do not bleach."
Some tags use a tiny hand to denote hand-washing, and the list goes on. By paying close attention to care labels and following their instructions, you have a better chance of keeping your clothes in fabulous condition.
Here's a breakdown of the basic symbols:
- A circle by itself means dry cleaning or wet cleaning
- A circle inside a square means tumble dry
- A triangle means bleaching is allowed
- A crossed-out triangle means do not bleach
- A hand means hand-washing is required
Understanding these symbols can help you properly care for your clothes and prevent damage. It's also a good idea to sort your clothing by type and color to ensure you're using the right wash cycle for each garment.
In the USA, a textile labeling law dictates the specific order in which the five key care symbols must appear, ensuring consumers can easily interpret them. By following these guidelines and using the symbols as a reference, you can ensure your clothes are cleaned and cared for properly.
It's worth noting that some manufacturers only use symbols, and the FTC suggests that those using just symbols provide additional information so that consumers can understand the care label.

Rules Vary by Country
The rules of care symbols vary by country, which can be confusing when traveling or shopping online.
In Australia, garment makers write instructions in plain English, making it easier for locals to understand.
In Europe, pictograms are required on textile labels, while in the US, they are voluntary.
The international standard ISO Standard 3758:2005(E) is used in Europe and has some differences from the ASTM symbol set used in North America.
In Asia and North America, you'll see a symbol that means "do not wring" or "do not twist" when washing.
Line drying is also a common care instruction, which means you should hang the garment to dry rather than putting it in a dryer.

Temperature and Machine
Temperature and machine are closely related when it comes to laundry. Understanding the temperature symbols on your clothes can help you choose the right wash cycle.
The temperature of the water affects how clean your clothes get and how well they withstand wear and tear. Cold water is ideal for delicate items and can be used for clothes with a single dot symbol, which indicates a temperature between 65°F and 85°F.
The more dots on the symbol, the higher the water temperature. Two dots indicate warm water with a maximum temperature of 105°F, while three dots mean hot water with a maximum temperature of 120°F.

Tumble dry symbols indicate that it’s safe to dry your garment in a machine dryer.
However, it doesn’t mean you are required to.
Machine
Machine cycles are more than just a guesswork - they're actually pretty straightforward.
The Normal Cycle is for stronger, more durable garments like t-shirts, socks, or jeans that can handle more agitation.
Permanent Press Cycle is for synthetic fibers like polyester that are specially treated to guard against wrinkles.
The Delicate Cycle is for more delicate garments that could be prone to damage, and it uses low agitation, slow spin, and colder temperature water.
Don't forget to look out for dry clean signs indicated by a circle, or hand wash symbols indicated by a tub of water with a hand sign, so you'll know when to avoid putting garments in the machine.
