Bests & Worsts Reviews from Amazon

1) This chemical compound is extremely hygroscopic, meaning that it absorbs water very well. If left in its cardboard box in a nice moist place, like in your kitchen or laundry room, it will get "mushy" and then will dry out to be as hard as a brick and impossible to use. Store it in an air tight container, preferably with some silica packs. 2) It will NOT dissolve in cold water. If you are using this with your laundry soap, you must either wash in warm water or dissolve this in warm water prior to adding to laundry. Some people pre-dissolve it and put in a pump bottle for use as a laundry booster. 3) TSP is NOT a detergent, per say, it acts as a rinse agent by suspending particles in water. It keeps the solid residue (the dirt/food/water minerals/detergents, etc) in your washers from re-adhering once your detergent has gotten the dirt off. It will not "clean" your dishes like soap does, but over time things will get cleaner as gunk that gets washed off doesn't re-adhere. 4) Use this product sparingly! One reviewer on here uses ¼ cup per dish cycle and that is insane! It was originally found in dish soap UP TO 6 percent. Start with a half teaspoon per dish cycle and give it some time. It helps your detergent work better, it does not replace it.
