Tri Sodium Phosphate (TSP)

TSP or Trisodium Phosphate, is a packaged, blended cleaning agent that comes in the form of an unscented dry powder that must be properly mixed into hot water to make a generally clear, albeit somewhat hazy, solution.

When used with sponges or scrub brushes, Trisodium Phosphate is an efficient, heavy-duty cleanser for sooty, oily, or unclean places around the house.
