I'm talking about the common bottles with household cleaners in them that spray when you squeeze the trigger. Well before the contents are used, the trigger usually becomes sticky/sluggish and takes a long time to fully return to the "relaxed" position, ready for the next squeeze. I've tried soaking the head in water, squirting it with light oil, applying liquid dish detergent as a lubricant. None really solves the problem.
