If you find powdery clothing stains on a freshly washed load of laundry, the cause can usually be traced to one of two culprits:
Here's how to make powdery clothing stains a thing of the past, and help ensure future loads of laundry emerge from the wash cycle clean and powder-free.
The right wash water temperature can help ensure you aren't left with powdery clothing stains. Set the wash water temperature to warm for best results.
This is because laundry detergent is designed to be activated by warmer water, allowing it to dissolve completely in the wash water and be carried away in the rinse water - not redeposited back on your clothes.
Add an extra rinse cycle to each wash load. This can help ensure any powdery residue coming from your laundry detergent is fully washed away in the rinse cycle.
Often, placing the laundry detergent in on top of garments can be the sole cause of powdery residue. Add your detergent before you toss in the dirty clothes to prevent it from becoming stuck on clothes.
A more common culprit, however, is a packed washing machine. Too many clothes in a load doesn't allow the machine adequate space or water to get clothes fully clean and can result in laundry detergent remaining on the clothes after the cycle is complete.
Finally, if nothing else works, consider changing to a liquid laundry detergent.
