It’s no secret that dirty clothes cause spots. But what about dark spots? After washing your clothes, do they turn into serious nuisances?
After taking a spin in the washing machine, your whites will become dingy and your colors will become muted. Depending on the dirt and sweat absorbed from the fabric, these staining substances can form both temporary and permanent dark spots.
You may be wondering what to do if you NOTICE dark spots after laundering your clothes but are daunted by the thought of getting them off. Follow these simple tips and you’ll be able to tackle any stain with ease!

Causes of Dark Spots on Clothes
Detergent or Fabric Softener Build-up
One of the common causes of dark spots on clothes after washing is the accumulation of detergent or fabric softener residue. Over time, soap scum can build up in your washing machine’s drum or on the fabric itself. When the clothes rub against the residue, dark spots can appear. To avoid this, it is important to use the right amount of detergent and fabric softener as instructed on the packaging.
Grease Build-up
Another culprit behind dark spots on clothes is grease build-up. This can occur when liquid fabric softener or oily substances from previous loads of laundry accumulate over time. The greasy residue can transfer onto your clothes during the washing process, leaving behind dark spots. Regular cleaning of your washing machine’s drum and dispensers can help prevent this issue.
Mold Build-up
In warm and humid environments, mold can thrive and cause dark spots on clothes. If your laundry area is not properly ventilated, mold can grow on the walls or inside your washing machine. When the clothes come into contact with the mold, they can develop dark spots. It is essential to keep your laundry area well-ventilated and clean to prevent mold growth and its subsequent effects on your clothes.
Washing Whites and Darks Together
Mixing whites and darks in the same wash load can result in unwanted stains and dark spots. The dyes from dark-colored clothes can transfer to the lighter ones, leaving behind visible marks. To avoid this, it is recommended to separate your laundry into different loads based on color. This practice will help maintain the integrity of your clothes and prevent cross-color staining.
Detergent Not Dissolving
When the detergent does not dissolve completely in the wash water, it can come in direct contact with cotton clothes, leading to the formation of dark spots. This can occur if you overload the washing machine or use a detergent that is not suitable for your machine’s settings. To prevent this, make sure to follow the manufacturer’s instructions for the proper use of detergent and check that it has dissolved completely before adding your clothes to the washing machine.
Preventive Measures
To prevent dark spots on clothes after washing and preserve the quality of your garments, consider the following preventive measures:
Using the Right Amount of Detergent and Fabric Softener
Proper dosing of detergent and fabric softener is crucial to avoid the build-up of residue on clothes. Follow the instructions on the packaging to determine the appropriate amount for your laundry load. Using too much or too little can result in poor cleaning performance or leave behind residue that causes dark spots.
Regular Cleaning of Washing Machine’s Drum and Dispensers
To maintain a clean washing environment, it is essential to clean your washing machine’s drum and dispensers regularly. Remove any accumulated residue, such as detergent or fabric softener, that may cause dark spots on clothes. Refer to your machine’s user manual for specific instructions on how to clean these components effectively.
Washing Whites and Darks Separately
To prevent color bleeding and the transfer of dyes, it is advisable to wash whites and darks separately. This separation will minimize the risk of dark spots caused by color contamination. Take the time to sort your laundry before washing to ensure each load receives the appropriate treatment.
Ensuring Complete Dissolution of Detergent
Before adding your clothes to the washing machine, double-check that the detergent has dissolved completely in the water. This step ensures even distribution and prevents direct contact between undissolved detergent and your clothes. If you notice any residue or clumps of detergent in the drum, consider using a different brand or adjusting your machine’s settings.
Regular Servicing of the Dryer
A malfunctioning dryer can contribute to the appearance of dark spots on clothes. Rust or oil build-up inside the dryer can transfer onto your garments during the drying cycle, leaving behind stains. To prevent this, schedule regular servicing of your dryer with a professional technician. They will ensure that your dryer is in good condition and free from any potential sources of stains.
Removing Dark Spots on Clothes After Washing
Dark spots on clothes after washing can be caused by a variety of factors, including detergent and fabric softener buildup, oil stains, rust, color runs, and objects left in pockets. Here are some possible solutions to remove these stains:
- Mix oxygen bleach and water: Mix a solution of oxygen-based bleach (such as OxiClean, Nellie’s All Natural Oxygen Brightener, or OXO Brite) and tepid water following product directions. Submerge the garment and soak it before washing it.
- Use lemon juice: Pour 2 cups of lemon juice into the washing machine and complete a wash cycle (without clothes or detergent) to get rid of dark stains.
- Use white vinegar or bleach: Place a cup of white vinegar or bleach through the machine on an empty cycle to remove dirt, stains, or mold.
- Try a commercial stain remover: For particularly stubborn stains, you might have to resort to a commercial stain remover.
To prevent dark stains on clothes, clean washing machines at least once a month. Additionally, avoid washing whites and darks together, as there’s a chance the dye from the dark clothes can transfer to the whites, resulting in unwanted stains. Finally, always check your washing as you remove it from your washing machine and catch those dark stains while they are still wet to give you the best chance of getting rid of them.
Conclusion
Dark spots on clothes after washing can be a nuisance, but understanding the causes behind them and implementing preventive measures can help you maintain the quality and appearance of your garments. By using the right amount of detergent and fabric softener, regularly cleaning your washing machine, separating whites and darks, ensuring complete dissolution of detergent, and servicing your dryer, you can minimize the occurrence of dark spots and enjoy clean, spot-free clothes.
