Let me think about this more...
First of all, I make sure I put the correct number of pods and amount of additives based on load size and not overload the machine. Second, I add scent enhancers if I want them real fresh, but not too much. Third, it's my own laundry, so I just stick to what I know best, which is a normal cycle. If I did an express cycle for everything even the largest, dirtiest loads, things will not go well at all. An example would be a full load of play clothes with ground-in dirt, farmers' clothes, or clothes from construction work. Another example would be smelly sports jerseys and football uniforms. If I tried what this so-called laundry guy is suggesting, chances are that the dirt would be baked into the fabric and bad smells will result, forcing me to redo them all over again.
Let's not forget about set-in stains like blood, chocolate, sweat, and ground-in dirt. The last time I checked, those require long washing and soaking times in cold or cool water to get out, maybe warm at the hottest temp maybe about 100 degrees Fahrenheit with a strong detergent like Tide or Persil and a long drawn-out normal or heavy duty cycle, or even a soak cycle. I've done this in my dad's Kenmore Elite front loader, where I put a blood stained pair of dark jeans in with other dark blue clothes on the normal/casual setting on cold and accelerated wash which is the equivalent of LG's turbo-wash with the soak option added as well.
What I'm saying is that 2 measly tablespoons of soap, not detergent, but soap won't work and especially with express cycles on the toughest loads, even the big, heavily soiled ones. 30 or less minutes, much less 15 minutes won't cut it, much less put a dent in trying to remove all the grit, dirt, grime, sweat, and odors somebody is trying to remove. I've been doing laundry since I was 7 years old, and I believe I'm not doing laundry wrong. I go by the manual and what I expect the washer to do, not a so-called "expert" that cites a flimsy study which only yields negative results and causes washers to smell stinky down the road. That's what I have to say.
Oh, one last thing. I don't see colors lasting the way this so-called "expert" is trying to tell us. Again, the contaminants that I just described are not being completely removed, therefore causing more laundry problems. Can you imagine walking around and receiving dirty looks because they saw you looking disheveled? What about somebody smelling your dirty laundry when you walk by them a few feet away. That would be completely embarrassing. This may be slightly off topic, but I can tie it in. I've smelled people's clothes smell so bad when they've walked around. I can just picture that wretched dreadful disgusting smell, and much worse with what this guy is suggesting. I can also imagine the sounds of clothes rustling around and that smell hitting you right in the face, causing me to cringe over it. They're probably screaming, "Help me, help me!"
