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.

Lab Glassware

Cleaning Glassware with Adhesives and APIs

Q. We have glassware that contains adhesive and API dissolved in organic solvents. If we do not do additional organic rinses prior to the aqueous rinses we have issues. Is there any way we can avoid the organic rinses?
A. To avoid organic rinses, you can soak in a high emulsifying cleaner such as a 1% Alconox solution (1.25 oz/gal or 10 g/L) prior to aqueous rinsing. Ideally soak in a warm or hot solution for fastest and most reliable results. The emulsifiers in Alconox will emulsify the solvents and active pharmaceutical ingredients (API). Be sure to rinse at the same temperature you are soaking at so you do not break the emulsion and redeposit the API or solvents. If you soak hot . . .

How to Clean Mold Release Agent from HDPE parts?

Q. We are looking for a product that will allow us to clean mold release agent from the surface of molded HDPE parts. A. The best way to reliably remove silicone based mold release agents is to immerse the HDPE parts in very hot (170ºF) 2% Alconox detergent followed by a very hot (170ºF) rinse, ideally both in ultrasonic tanks. After the first very hot rinse, normal ambient temperature rinsing can be done. This can also be done with stiff brushes, but of course protective equipment must be worn.

The theory behind this is that …

One Detergent for Mold Release and Circuit Board Cleaning?

Q: What types of Alconox, Inc. detergent would I use to clean a mold release agent? As an aside, is there any chance I could use the same detergent to also clean copper traces off a printed circuit board?

A: Yes! You may indeed be able to use one detergent in both these cleaning applications. But it will only work if the copper is not in the form of an oxide. Here’s why.

Industrial 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?

A: For the highest level of cleanliness, you only use a solution once. In general, in a medical device manufacturing and cleaning operation, a detergent bath will typically easily last for 8 hours.

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 …

Medical Device Cleaning: Martensitic Stainless Steel

Q: We use Alconox® on the medical device parts we manufacture that need cleaning before shipment. Alconox® detergent is working in an excellent way with austenitic stainless steel parts, but is not working that well with martensitic stainless steel. Actually, at the end of the process cleaning martensitic steel, we notice some marks on the material. Any recommendations?
