How to Set Colors in Clothes

While your most loved clothes are bound to fade a bit over time, there are several ways to easily set the color to prolong the lifespan of your colorful clothing. Use white vinegar or table salt to set the colors when your clothes are new, and maintain good washing practices to ensure that your clothes stay clean and bright.

1
Load your new clothes into the washing machine by color. First, divide the items that you want to set by color. Then, put a single-color load into the washing machine drum, spreading them out evenly. For best results, limit the number of items to a small load (about 1 to 4 items).
- While you may choose to mix colors in the washing machine after the initial wash, you will want to separate them out for the first wash in order to accurately set the color in with vinegar.
2
Choose distilled white vinegar to avoid discoloration. Distilled white vinegar is generally the best option for effectively setting color in clothes without any risk of damaging the fabric. While some popular vinegars, such as red wine vinegar and apple cider vinegar, have a natural color that may effect some clothing fabrics, distilled white vinegar is safe to use on your clothing.^{[1]XResearch source}
- Distilled white vinegar can be found at most grocery stores, or you can order it online.

Pour the distilled white vinegar onto your new clothes. First, put your new clothes in the washing machine. Then, pour ½ to 1 cup (240 mL) of white vinegar on top of the clothes, depending on how large your load is. The vinegar smell might be strong but don't worry – it should dissipate in the wash.^{[2]XResearch source}
- For best results, only add the clothes you want to set color in, limiting to a few items.
- You do not need to add laundry detergent when washing with white vinegar, as the vinegar will disinfect your clothing.

Set the washing machine on the rinse cycle with cold water. To avoid breaking down fabrics or causing the dye to run, select the cold water option on your washing mashing.^{[3]XExpert SourceKamel Almani
Laundry & Cleaning SpecialistExpert Interview. 13 April 2021.} Then, select the rinse cycle before pressing the “start” button.
- If your washing machine doesn't have a rinse cycle option, choose a low agitation, quick wash option.
5
Air dry the clothes for best results. Lay your clothes flat on a clean surface or hang them up to dry. While you can run your clothes through the dryer if you prefer (or if you need them done quickly), heat causes the fabrics to break down faster, causing your clothes to fade. After the vinegar has helped set the color, air drying helps keep colors bright and fabrics strong.^{[4]XResearch source}
- While the vinegar smell should evaporate during the rinse cycle, if there is any residual smell, air drying should get rid of it.^{[5]XResearch source}
- In addition to setting the colors, vinegar cleans and sanitizes your clothes, so you won't need to run them through again with your regular detergent until they are in need of another wash.
- Distilled vinegar also can even work as a natural fabric softener.^{[6]XExpert SourceKamel Almani

- While you may choose to mix colors in the washing machine after the initial wash, you will want to separate them out in order to accurately set the color in with salt.

Add laundry detergent to your new clothes in the washing machine. Place the new clothes that you want to set color into in the washing machine. Then, add your regular laundry detergent, following the directions on the label.
- Make sure that your detergent does not contain bleach.
3
Add table salt to your laundry. Depending on how big your laundry load is and how much detergent you've added accordingly, add 1 tablespoon (15 mL) to ¹⁄₂ cup (120 mL) of white table salt.^{[7]XResearch source} Adding table salt to the first cycle for new clothes can help set the colors and keep them from running during future washes.
- If you are only trying to set the colors in one piece of clothing, for example, use only 1 tablespoon (15 mL). Increase by 1 tablespoon (15 mL) per additional piece of clothing.
- Adding salt to your wash cycle during future washes may also help faded colors become vibrant again.^{[8]XResearch source}
If your washing machine has several wash cycle options, select the wash cycle appropriate for your particular clothing item. If your clothes are made out of a delicate fabric, for example, you will likely want to choose a short, low agitation setting.
Lay your clothes flat on a clean surface or hang them up to dry. While you can run your clothes through the dryer if you prefer, the heat will start breaking down fabric and, over time, cause your clothes to fade. Air drying helps delay this and keep the colors bright.^{[9]XResearch source}

Spot clean between washes. The more you wash your clothes, the more the colors will fade. To help your clothes stay bright after you set the colors, spot clean with cold water and detergent to keep your clothes clean while washing as little as possible.^{[12]XTrustworthy SourceCenters for Disease Control and PreventionMain public health institute for the US, run by the Dept. of Health and Human ServicesGo to source}
- Synthetic fabrics like polyester are more sensitive to heat and tend to break down faster than natural fabrics, such as cotton. Therefore, they should be washed less to maintain their colors. To avoid over-washing, spot clean synthetic fabrics whenever possible.^{[13]XResearch source}

Wash your clothes in cold water. While warmer water is helpful when you are trying to remove stains, it also breaks down dye in fabric.^{[14]XResearch source} Whenever possible, wash with cold water to help set the colors in your clothes and keep them looking bright.^{[15]XExpert SourceKamel Almani

Before putting your clothing in the washing machine, turn them inside out.^{[16]XExpert SourceKamel Almani

Question
What about colored towels?
Community Answer
Colored towels are washed the same way as white towels, taking care to avoid using fabric softeners or dryer sheets which prevent the towels from absorbing liquid. Instead, hang-dry your towels or tumble dry on the lowest setting to limit static.

Question
Do I add detergent or just salt?
Community Answer
You add both detergent and salt for best results. If your washer has a detergent area, you can add the detergent there, and the salt above the clothes.
