Concentrated acidic pH 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 on granite, porphyry, basalt, clay brick, hard stone, Serena stone and mineral finishes, and in general on all mineral materials that, due to their chemical composition, are not sensitive to the acidic nature of the cleaner. Its formula renders it suitable for the removal of light layers of rust from metal surfaces. Do not apply the product to surfaces in limestone-matrix stone such as marble, travertine and Lecce stone, lime paint or surfaces that are delicate, polished or lead polished.
