Hygiene products

Cellar hygiene products effectively target both organic and mineral stains. Alkaline detergents are used for organic residues with a low pH, while mineral deposits with a high pH are removed with acid products such as nitric acid. Soda, an alkaline detergent, is widely used to clean wine-making equipment.
To disinfect and eliminate micro-organisms, peracetic acid is increasingly favoured for its rapid effectiveness, replacing chlorine, banned to avoid cork taint.
Hygiene products also include surfactants, sequestering and oxidising agents for optimum cleanliness.

Descaling products

The descaling product is a powerful alkaline based on soda (sodium hydroxide). The soda attacks and dissolves the wine scale (tartaric acid). The effect of the soda is enhanced by the presence of surfactants. The descaling product is generally applied at room temperature, unless the supplier specifies otherwise. The descaling product can also be made up of powerful alkaline products with added surfactants.The descaling product is used in a closed circuit under hydrodynamic conditions (pressure, flow rate, temperature) that favour its action, via a washing nozzle (tank).
