Deconex 34 GR

Deconex 34 GR

Acidic cleaning concentrate for medical
instruments made of stainless steel

For the application in soaking and ultrasonic baths. Also suitable for cleaning washing machines. Free of alkalis, liquid.


deconex 34 GR is an acidic cleaning concentrate for stainless  steel surgical and ward instruments. It is being used for the removal of annealing colours, water spots, transferred/initialrust and encrustations, which are resulting from inadequatereprocessing.

The process‘ weak points may be:

  • ƒ poor water quality
  • ƒ insufficient cleaning
  • ƒ usage of unsuitable cleaning products and disinfectants
  • ƒ processing errors and
  • ƒ poor vapour quality in the sterilizer

If surface changes such as described above, will appear on instrument surfaces, the whole process must be checked. The instruments concerned should be treated with deconex 34 GR, either in an ultrasonic or in a soaking bath.

Brand-new instruments must go through an initial reprocessing cycle, before they are being used for the first time. Despite this pre-treatment, instruments made from minor steel qualities show an irreversible greyish-black colouring after the first sterilization.

By Treating such instruments with deconex 34 GR prior to the first reprocessing cycle, the colouring can be prevented.

deconex 34 GR can also be applied for removing silicate coatings in washing machines.

  • deconex 34 GR is based on acids and surfactants and effectively removes inorganic contamination and coatings like:
  • silicate coatings shining in various colours (annealing colours)
  • ƒspots resulting from water with high salt content
  • ƒ initial rust resulting from contact corrosion, e.g. contact with brass parts during processing and from transfer red rust
  • ƒ plaster residues on plaster scissors andƒ encrusted brownish organic residues
  • deconex 34 GR is exclusively suitable for stainless steel.
