This is another time that a customer has contributed to the solution of a problem.
I provided the test ideas and the customer did all the real work.
Anyway, here are the two emails:

Ahhh...young Grasshoppa...do not fear....Doctor Thomas has never lost a patient ...yet...
Why oh why only on the chest area of dark shirts.......
This has to be a very important fact .....somehow...
Lets assume you have mold in the outside tub
Most of it gets flushed out but some can remain distributed over the laundry.
(this is actually very common in contaminated machines but it normally does not have anything to grow on so you don’t see the spots)
OK here is a wild scenario regarding why this is happening only on certain types of laundry and only in certain but “random” areas:
Given: The areas of the shirts that are more likely to have sweat and body oils on them are also more likely to have the black spots.
Given: Dark clothes are washed in cold / cool water.
A very thin residue of oils and greases could be left behind and the detergent attaches to it.
All this provides food for the mold and nasties......
This is starting to make sense...
It is very hard to remove body oils, pizza grease and similar stuff in cold water.
Next, the detergent residue and gunk from the machine that is floating in the water is deposited on the laundry.
The areas with deposits of body oils, pizza grease and stuff will encourage growth much faster than a really clean area.
So, you get splotches and dots “randomly” growing on the piece of clothing as the load goes through the dryer. Wow, the mildew must grow really fast for there to be stains so quickly....or there is a lot more contamination growing in the machine than is assumed so it leaves a lot on the garments.
OK.... here is an experiment.
Take three items that should show the black spots.
Soak them in a solution of 2 cups vinegar, 1 oz table salt and 1 oz of dishwasher detergent mixed in a gallon of hot water for an hour. Sorry it has to be hot but not scalding hot..
This is a mild "water based organic stripper" formula that should remove any light weight oils and greases from the items. It will also remove any detergent residue from the last wash.
It also looks mysteriously like my Super Shock treatment........
(It also works really good getting the sweat stains out of baseball caps and when cleaning (soaking) pool filters. Oils from people can be very tenacious.)
Now, rinse and let dry.
Then throw these items into the washer with a load the should show spots

I have been doing some "experiments" on the spot problem.
I have come to the conclusion that it is probably the HE detergent.
(She is correct: Detergent sticks to the oil coated fibers much more than the clean fibers. And then, it doesn’t rinse out and causes the problem -- just like it sticks to plumbing and does not rinse out easily with hard or cold water.)
Let's start with the navy blue, black and red T-shirts that are affected.
Before laundering them, the front of these shirts had some food spots and I guess some sweat, usually in the chest area. What's puzzling after laundering is that dark spots show anywhere on the shirt -- not just on the food spots -- and sometimes the dark spots do not appear on the food spots.
I started out following your experiment below. Process: Shirts that should show spots were put through your mild organic stripper process, rinsed, dried, put in washer with shirts that should show spots, but were NOT put through mild organic stripper process, then all shirts put in washer, withno more than a tablespoon with Tide HE detergent in dispenser, followed by 3/4 scoop of TechnoFresh. RESULT: Shirts that went through organic stripper process had spots after drying -- but very few. Shirts that did not go through organic stripper process had A LOT OF SPOTS after drying.I then tried the same process, but put the HE detergent and your product in the drum instead of the dispenser before inserting clothing.
Result: Spots after drying -- no difference whether clothes were put in the washer before dispensing of soap -- or mixing the soap in the drum, then inserting clothing.
Then I needed to see if I could get rid of the dark spots.
Strayed each spot on each shirt with a degreaser, put the shirts into the washer WITHOUT detergent, but used 1/2 scoop of NuFresh - RESULT: After drying NOT one spot.
I then started to separate the dark colored shirts from the rest of the laundry and "hand laundering" them. I use your organic stripper process, still wet, put clothing in washer, 1/2 scoop of NuFresh, wash on WARM -
After drying NOT one spot.
Alternatively, I also sprayed a degreaser over the full front of unlaundered shirts, washed in a bucket of Dawn dishwashing soap (did not do the mild organic stripper process), put clothing in washer, 1/2 scoop of NuFresh, wash on WARM - After drying NOT one spot.
I have been using HE detergent, no more than 1 tablespoon and 1/2 scoop of NuFresh with all other laundry, other than darks, no spots on clothes.
Perhaps there are spots but do not show up on light clothing ?? Thanks to your product, the clothes ALWAYS smell great.
I have withheld using HE detergent on dark clothing throughout the month and have not had spots. I have not tried another brand of HE detergent.
What do you think?
I love your product. Never stop making it.
I'm putting in another order!
