The title pretty much says it all. I have a couple of 25 ml bottles of Bostick and Sullivan standard Platinum solution number 3. Down to the last 4 or 5 ml in the bottles and they have gotten quite a lot of red crystals in them. I have added 8 drops of distilled water to each and heated them in a tray of hot tap water and shook them till I was late for dinner and left them sitting all night and in the morning no improvement at all. Does anyone know what I should do?


Thanks Dennis Purdy
