thermosept® citro S is ideally suitable for neutralization following alkaline cleaning (for example with thermosept® Kraftreiniger A).
thermosept® citro S is free of phosphates, surfactants, colour and perfume additives.

Instructions for use

The concentration, temperature and contact time should be established via applicable practical tests. The following concentrations are often used for the respective applications:
  • Neutralization following alkaline cleaning: 0.1 - 0.5 %.
  • Following neutral cleaning: 0.1 %.
  • For descaling of machinery: 0.3 - 0.5 %.
The use concentration during the application can be controlled via conductivity measurements. The respective conductivity data at different concentrations and temperatures are available upon request.
Following product application all surfaces should be rinsed with water of at least drinking water quality.
The use solution of thermosept® citro S is temperature stable up to 94 °C.
