In the hustle and bustle of modern life, washing machines have become indispensable appliances, simplifying the task of laundry for countless households. These efficient devices save time and effort, ensuring that our clothes emerge fresh and clean after each wash.

However, despite their convenience, concerns have arisen about the potential of washing machines to cause unintended damage, particularly in the form of staining clothes. So, can washing machines stain clothes?

We will explore the common causes behind such mishaps. These preventive measures can be taken and offer valuable tips to ensure your laundry experience remains hassle-free and your clothes stay spotless.

Can Washing Machines Stain Clothes

Can Washing Machines Stain Clothes?

Unfortunately, yes. Improper use may stain the clothes and make them dirty instead of clean. What causes the stains is often the detergent, softener, dirty machine tub, or plumbing issue.

To determine the cause, you should inspect the size and shade of the stain. After that, you can easily find a solution to remove it.

Overloading the machine might also be one of the reasons for stained clothes. The detergent and softener can not reach each piece of clothing, which is why some clothes might come out stained and incompletely cleaned.

If the stain is caused by tub dirt, it might be time for routine washing machine cleaning.

Nevertheless, let me explain to you how to inspect the stain and determine its cause. After that, you can easily find a solution to remove it.

Stain Causes and Stain Removing Solutions


Detergent and fabric softener

The most common stain cause is the wrong choice of detergent or fabric softener. Powdered detergent might cause white stains on dark clothes, while fabric softeners might cause oily stains on clothes of any color.

The softener is good for the clothes but in recommended amounts. You should always follow the instructions on the product label. One cup means one cup. If you pour more than recommended, it might stain your clothes.


Overloading the washing machine is not a good idea. If you usually overload the washing machine intending to save more time and electricity – you are wrong.

If the washer is too full, the detergent and softener can not reach each cloth properly. This might lead to stains and incompletely rinsed clothes after washing, so you might have to re-wash them and forget about saving energy.

Stain Causes and Stain Removing Solutions

Leftover object

Washing machines use high water temperatures that might melt or break an object that is not supposed to be inside them. However, everyone might forget to check their pockets and forget something inside their clothes.

If the stain looks unusual and makes you wonder how this happened, check for leftover objects. Find the cause and re-wash the stained clothes.


Since the washing machine tub is a humid place, it creates perfect conditions for mold and mildew formation. You might see mildew on the washer’s door and rubber seal.

If your clothes come out with smaller black stains, then the cause is definitely mildew.

Clogged pump and plumbing issues

If your clothes come out with brown, greasy stains, then the cause might be an internal issue or defect. If the water pump is clogged, the machine will not flush away the dirt.

Instead, it will return it back to the tub and make the clothes stained and dirty.

Dirty washing machine tub

Your washing machine needs cleaning over time. Hard water, dirt, and mildew might make the tub dirty and stain your clothes. If the clothes you have just washed are stained with white marks, the cause might be hard water.

If the stains are brownish, the cause might be loose dirt from previously washed clothes or shoes.


  • Re-wash – If the stain caused is a leftover object or power detergent marks.
  • Baking soda and vinegar – If the stains are brown and greasy.
  • Bleach – For removing any stains on white clothes ONLY.
  • Stain remover – You can use this product on all clothes and stains.

Preventive measures

Routine cleaning

Clean the machine tub with bleach if there is mildew; or white vinegar if there are hard water stains and dirt inside the tub.

Then, you should run the hottest and longest program.

Liquid detergent

Replace the powdered detergent with liquid for dark and colored clothes.

White vinegar

Replace the fabric softener with white vinegar if the softener often causes stains on your clothes.
