Product description

Arkema’s Scaleva® is a powerful new generation acid for efficient derusting and descaling applications, especially for the tough calcium scales targeted by dairy and brewery cleaning formulations. For (clean-in-place) CIP and (blast-in-place) BIP systems, Scaleva® helps reduce cleaning time and waste treatment costs.

  • Promotes rapid attack on carbonate and oxide scales
  • Enhanced dissolution and removal of salts for potential rinse reduction
  • Less damaging to pipes, fixtures, and vessels compared to other strong acids
  • Dilute solutions safe for discharge to waste treatment facilities
  • High thermal stability and non-oxidizing
  • Compatitble with non-ionic surrfactants and most biocides

Customer benefits

Scaleva Methane Sulfonic Acid (MSA) is used for derusting and descaling applications
  • Faster reactions
  • Improved processing
  • Nitrogen and phosphorus free
  • Strong acidity (with low-corrosion
    formulation available)
  • Non-oxidizing and non-foaming
  • High solubility of post-cleaning salts for dissolution and removal
  • Stable with strong oxidizing agents (formulates safely with hydrogen peroxide, peracetic acid)

Common applications

Scaleva® is the solution for descaling applications including cooling towers, evaporative coolers, hot water boilers, processing equipment and more.

Scaleva® is used in Food & Beverage, concrete, household, petrochemicals, and formulated cleaner applications.


Scaleva® is the best acid choice to replace fuming, weak, and environmentally polluting acid.

At the same active concentrations, Scaleva® does a better job in 15 minutes than phosphoric acid does after 45 minutes.

For stainless steel cleaning that requires high acid content, we recommend our MSA LC grade.


Scaleva® is REACH certified and NSF registered. It contains no phosphorus or nitrogen, making it environmentally friendly and less corrosive than other strong acids. It is listed as a safer chemical by EPA and is biodegradable.

Scaleva® can be formulated with a number of products to improve overall efficiency and efficacy of your cleaning mixtures. This may reduce the number of cleaning steps involved and the amount of water used.

Scaleva® is available in drums, totes and bulk. Contact a specialist for a free sample.
