Soap powder residue on clothes from washing machines
If you notice that some of your items have streaks of detergent at the end of the cycle, it is caused by over loading the machine, not a fault with the machine itself.
If you overload the machine, the clothes become a tight mass which means that neither the water nor detergent can penetrate to all the clothes. The overall result is that none of your clothes have been washed or rinsed properly, and some items may well be streaked with undissolved detergent.
It is very simply to resolve this issue, place the affected items into a rinse and spin programme with no detergent, and the undissolved detergent should simply be rinsed away, leaving no permanent damage.
Take a little more care when you are sorting clothes for the washing machine. Apart from keeping colours sorted, try to avoid putting delicate items with heavier weight items. What will happen is that the delicates will become entangled with the heavier items, neither will be washed properly and, in fact, the more delicate item may become damaged.
Check the care labels on each item, and only select the lowest temperature recommended across the load.
Never overload the machine as the outcome is that the wash will need to split down and rewashed in at least two loads. Loss of time, excessive use of electricity, water and detergent. Not to be recommended.
