Concentrated acidic pH stone cleaner made with special biodegradable emulsifying agents and surfactants capable of attacking and dissolving the components of organic and weather-related dirt (smog, hard-water streaks, excrement, etc.). Its balanced formula allows for intervention without altering the colour of surfaces, in full respect for the surface to be cleaned.

NOVAPIETRA A can be used for cleaning porphyry, granite, basalt, clay brick, pietra forte, pietra serena and mineral finishes, and generally on any mineral material that is not sensitive by chemical composition to the acidic nature of the cleaner. Its formulation makes it suitable for removing light patinas of rust from metal surfaces. Do not apply the product to limestone matrix stone surfaces such as marble, travertine, Leccese stone, lime paints or Delicate surfaces, polished or plumbed.
