SUBLIME Descaler


SUBLIME® descaler is a water-based solvent containing wetting agents, corrosion inhibitors and degreasing compounds. It is designed to penetrate and remove encrusted lime scale, rust, and corrosion products and dirt from water-wetted surfaces in process equipment, commercial and industrial applications.

SUBLIME descaler has a pleasant citrus-lime fragrance that masks the obnoxious odors normally associated with dissolving water scale and corrosion. It is low-foaming and quickly releases the carbon dioxide (CO2 ) gas generated by the reaction of lime scale with SUBLIME.


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)
