Tech Tips: Effective Bushing Cleaning Practices

Cleaning Bushings with Hydrogen Peroxide: Prolonged Life or Sudden Death

 

Here at Potentials, Inc. we are regularly asked if it is a good idea to use hydrogen peroxide to clean bushings. We would like to share a few thoughts on the subject with all our clients. The suggestions below are based on our years of experience in the implant business as well as lengthy discussions with our trusted industry advisors.

First, use peroxide sparingly. Hydrogen peroxide is a very strong oxidizer and will help remove the “color” that builds up in the source area due to prolonged use. However, in addition to cleaning the bushing, the peroxide will also corrode metals and can decompose the composite material of the insulator. We strongly suggest you not allow the peroxide to contact the insulators or metal longer than necessary to clean. Bushings regularly arrive at Potentials, Inc. that appear to have been soaked in hydrogen peroxide. The soaking results in an almost white appearance and causes the bushing to become pitted, which are both highly undesirable results.

Next, avoid allowing hydrogen peroxide to seep into the small fissures between the insulator and the flange. Peroxide that is able to penetrate this area will be difficult to remove without completely removing the insulator from the machine. In addition, the peroxide will create its own arching problems if it is allowed to remain in the fissure.

Finally, remove all residual hydrogen peroxide with isopropanol or DI water. This recommendation will help mitigate the problems that arise from prolonged exposure presented above.

These recommendations should help you to add life to your bushing inventory. Potentials, Inc. is always a great resource for cost saving solutions for prolonged insulator life.
