Putting in service
Prior to 1st use, the new instrument shall be cleaned efficiently, using a detergent. This cleaning has to be as complete as possible, to eliminate any trace of machining oil or mineral contamination. This detersion has to be made by immersion in a controlled spot remover detergent, containing phosphates, polyphosphates and oily alcohols, for a period from 2 to 24 hours.
Rinse copiusly the instrument with hot water, dry it, then sterilize it. If the instrument has a normal aspect, it can be put in service. If brown spots appear, in particular in the articulation points or in the streaks, renew the full detersion operation, until full cleaning. caution : uncleaned sanding or polishing oil residue shall, after sterilization, give a rusty aspect to the instrument.
Whatever method is used, it is proper to:
• never to wash altogether chrome-plated and stainless instruments,
• avoid contact with aggressive solutions based on:
----halide ions : chlorides,
----iodides : iodized polyvinylpyrrolidone : betadine
----choose a good detergent :
----containing no chlorine nor chloride,
----containing no acid,
----containing no abrasives.
The best results are obtained using spot remover detergents containing :
• phosphates,
• polyphosphates,
• oily alcohol polyethyleneglycol,
• mineral salts with dabbed alkalinity.
The water that is used for cleaning shall be :
• filtered,
• drinkable quality,
• low contents in limestone, which means softened to between 6 and 8 TH if needed. A too hard water will inhibate the detergent and will let a white powder on the device after drying process,
• low content in chlorine elements or in chlorides : < 20 mgr/l,
• low content in mineral elements (mainly copper & iron),
• distrust of too much softened water that could contain very corrosive sodium chlorides (Caution of 2 water softeners in spate),
• prefer swaped or osmosed water for rinsing to any other purification system.

USE OF METALLIC BRUSHES AND SCOURING DABS FOR INSTRUMENTATIONS' CLEANING IS PROHIBITED.
