Why is there corrosion or spots on instruments after using the W&H Laboratory Equipment?
- T
  Todd FischerAug 18, 2025
  Corrosion or spots on instruments can occur due to several reasons: * Instruments were not dried before being placed in the sterilizer. * Poor water quality or water containing chemical substances was used. * Organic or chemical residues were present on the instruments. * The chamber, trays, or chamber rack are dirty. * Instruments of different materials came into contact. * Scale deposits are present in the chamber. To resolve this, ensure instruments are dry, use good quality water, clean instruments and the sterilizer regularly, and prevent contact between different materials.
