Review on 🧼 Earthborn Elements 10 LBS Sodium Tripolyphosphate - Powerful Cleaning Agent, Water Softener, Laundry Additive - 1 Gallon Bucket, Resealable Packaging by Jermaine Logan

STPP is used in washing machines and dishwashers to replace phosphates, which can no longer be added to commercial detergents or dishwashing detergents. Phosphates lower the pH of the water and prevent dirt and oils from sticking to fabrics removed by detergents. Prevents stains on glasses in the dishwasher. Don't use the cheaper TSP, it forms insoluble residue that can damage your washing machine or dishwasher. I like this brand for its very well sealed packaging as it is important to protect the STPP from moisture otherwise it will become unusable. When opening, there was no annoying dust. It's a very fine powder so it dissolves instantly. Small things have a big impact.
