Bro, most detergents use phosphate to remove stains. If some is stuck in there, test for phosphate in tank. Try throwing a gallon of vinegar through the washer. I know you can use it for cleaning, irons, coffee makers, and windows.
If you want bring by some water on your way home, ill test it with the hanna.
