How To Clean Carbide

Q:I was wondering if you have a product that I can use in an ultrasonic cleaner to clean tungsten carbide that would not leach out cobalt? That also can be disposed of down a drain?

A: Tungsten carbide (WC) cleaning comes with some inherent issues, and the cleaning cycle that accompanies it will depend entirely on the feed stock (components to be cleaned) that the process comes from. This is where Alconox, Inc., as the critical cleaning experts, excel from our experience and vast pool of applications to draw upon.

Ultrasonic Cleaning: Detergent Bath Life

Q: We manufacture medical devices. Can we use our Alconox or Citranox bath solution more than once? How do we know that we need to change the solution?

For example, you can make up a fresh Alconox® or Citranox® solution once a day and then verify that the pH has not changed more …

RO Membrane Cleaning Best Practices

Q: We are cleaning heavy scale compounds of Ca, Mg, carbonates, phosphates and organic matter from reverse osmosis (RO) membranes. Can you tell us some cleaning best practices and recommend a detergent?

A. If the organic matter is significant, a two-step process, cleaning by re-circulation or soaking (re-circulation may be more effective) could be needed. If the organic matter is biologic in nature, we would recommend Tergazyme® Enzyme-Active Powdered Detergent which is both a powerful emulsifier along with protein enzymes. If the organic residue is more of an oily nature…
