Why you should always use liquid detergent
For cleaner clothes and fewer washing machine issues, stick with liquid.
Liquid detergent is better at greasy stains and as well as for removing dirt.
Water temperature
Water temperature is a big factor. No matter if you choose cold, warm or hot, liquid detergent mixes with the wash water completely because it's already a liquid.
Some powder brands, on the other hand, don't dissolve as well in cold water settings, especially in high-efficiency washers. Since most of your clothes should be washed in normal temperature water to prevent shrinkage and dyes from bleeding, using powder may become a problem.
If the water temperature is under 68 degrees F (20 degrees C), you may find little clumps of leftover detergent on your clothes after a wash, requiring an extra spin cycle to remove them. This puts extra wear and tear on your washer and your clothes.
The health of your machine
Powder can also leave chunks of undissolved detergent in your washing machine parts. As you can imagine, this can lead to malfunctions. It particularly affects the washer's drainage system. Over time, the clumps can build up, causing a blockage that looks a lot like hard water deposits
