The invention provides a source of sodium thiosulfate via the dialysate used to cleanse the bool of toxic and metabolic waste in the patients undergoing hemodialysis, peritoneal dialysis, or gastro-intestinal dialysis for treatment of end-stage or near end-stage chronic renal disease. In the method of the invention, dialysis solution components contain therapeutic amounts of sodium thiosulfate, which when fully reconstituted for use as a single solution, deliver 20-130 mg/dl of dialysate.
