Aqueous Mild Alkaline Cleaner


Castrol Techniclean S Extra FF is an aqueous, mild alkaline industrial process cleaner, containing highly effective biodegradable surfactants and corrosion inhibitors providing superior temporary rust protection.


Techniclean S Extra FF is designed for inter-operational and final cleaning operations of parts and components, suitable for use in a wide range of industrial spray and intensive flood wash machines. It is capable of providing several weeks temporary indoor corrosion protection on ferrous metals, depending on storage conditions. Techniclean S Extra FF effectively removes soluble oils, neat cutting or light forming oils, thin corrosion protective films, lubrication oils and general dirt and shows excellent oil rejecting behaviour that allows removing the oil to ensure a long bath life.

  • Leaves a high performing temporary corrosion preventive film on the metal surface – minimises scrap rate which improves productivity.
  • Superior cleaning & corrosion protection in one process step – enables possible process rationalisation.
  • Low foaming at ambient temperature; allows for initial cold water start ups – economical, lowers energy cost.
  • Can be used in most spray wash equipment – enables possible product consolidation.
  • Good biostability and very good oil splitting support long bath-life – reduces maintenance and disposal cost.
