SUBLIME® descaler comes in a pale yellow color that changes to a deep bluish-purple when it is spent. The advantages to this color change are:
- You know when the solution is spent and should be discarded
- Don’t spend time circulating a spent solution,
- The color change occurs at a pH of 5.8 to 6.0 which is well within the safe disposal range of most of the current governmental waste regulations and
- If the equipment is clean and SUBLIME® has not changed color, you can save it and use it again.
SUBLIME is most effectively used by circulating through the equipment to be cleaned. When possible, circulation should be up-flow. SUBLIME® can also be used by filling the equipment to be cleaned and allowing it to set until scale has disappeared. The cleaning operation normally takes two to six hours.
SUBLIME is non-toxic, non corrosive, non-flammable and non-hazardous when used as directed.
SUBLIME descaler is registered as NSF-A3 and U.S.D.A. approved as specified in 40 CRF 261. and D.O.T. 173.240(a)
