I wash with earth choice liquid detergent with a couple of spoons of bicarb and always dry them in the sun for at least half a day but lately they have this wet smell...I've tried a cold water strip wash with earth choice dish liquid - I can't do hot or warm water with my machine. Any suggestions? Do I need to strip with a nastier dish detergent? I have had to finish drying them in the drier a few times lately as they have still been damp when I take them off the line at the end of the day.
