Hinged Instruments All hinged instruments — forceps, rongeurs, scissors, pliers, hemostats, orthodontic pliers, etc. — should be kept lubricated. Regular use of proper lubricants, like Instrument Lubricant Spray (ILS), will prevent rust, corrosion and stiff joints and will ensure smooth operation. (Household lubricants and handpiece lubricants are NOT recommended.) Instrument Cleaning All instruments need to be cleaned before they are sterilized. They should be washed with a non- corrosive, low sudsing neutral detergent. We strongly recommend the use of Enzymax™ Dual Enzyme Detergent to best protect and extend the life of the instruments. Instrument cleaning can be accomplished by ultrasonic cleaning, which is the method of choice to prevent hand injuries caused by hand scrubbing.

Sharpening Sharpen cutters regularly. How often depends on such factors as the frequency of use, types of applications the cutter is being used in, etc. Routinely inspect cutters to determine if sharpening is required. Sharp instruments cut more efficiently and regular sharpening will enhance the life of your cutter. With average use, we recommend sharpening your cutters every 6 to 9 months. Do’s & Don’ts of Processing Instruments For best results, we recommend the use of ultrasonics for instrument cleaning and steam autoclaves for sterilization. Never use tartar remover on instruments. For light stains, we recommend Shine reNEW™ Stain and Rust Remover (IMS-1455). Never spray surface disinfectant near instruments. Use only approved lubricant (Never use WD-40 or Handpiece lube).
Stainless Steel Instruments While stainless steel has superior corrosion
resistance, it will discolor and corrode when exposed to higher than recommended chemical concentrations or certain chemicals. Stainless steel should not be exposed to the following chemicals: Sodium Hypochlorite (household bleach), Tartaric Acid (stain and tartar remover), Aluminum Chloride, Barium Chloride, Bichloride of Mercury, Calcium Chloride, Carbolic Acid, Chlorinated Lime, Citric Acid, Dakin’s Solution, Ferrous Chloride, Lysol, Mercuric Chloride, Mercury Salts, Phenol, Potassium Permanganate, Potassium Thiocyanate or Stannous Chloride. The following chemicals should NEVER be used with stainless steel: Aqua Regia, Ferric Chloride, Sulfuric Acid, Hydrochloric Acid or Iodine.
Troubleshooting Problem Cause
Prevention
• Insufficient rinsing after ultrasonic cleaning
• Rinse thoroughly under steady stream of water for 30 seconds
• Rinse with hot water • Optional: Dip cassettes in alcohol after rinsing\
• Insufficient drying after ultrasonic cleaning
Spotting
• Not changing ultrasonic solution
• Solution should be changed at least once a day
• Sterilizers should be cleaned weekly • Use only distilled water for reservoir
• Sterilizer has not been cleaned
• Separate stainless and carbon instruments • For carbon steel instruments: Dip in pre-sterilized rust-inhibiting solution as suggested by sterilizer manufacturer • Rinse and dry instruments thoroughly • Use approved cleaning, sterilization solutions only • Never use household bleach or stain and tartar remover
• Corrosion from carbon steel instruments spreads to stainless steel instruments
Rust
Pitting
• Chemical attack on instruments
