Ultrasonic Cleaning of Glass Molds (Detergents vs. Alkali)
Q. We have heard that Alconox is recommended for glass mold cleaning. Other than release agent, can the product also remove oxidation from the mold surface? And finally, why is the concentration on the Alconox detergent only 1-3% when we typically use concentrations of 20-30% when cleaning molds with sodium or potassium hydroxide based chemicals?
A. Alconox® Powdered Precision Cleaner is what we tradtionally recommend for mold release cleaning applications, but many also find Detonox® Ultimate Precision Cleaner to be particularly effective.
When it comes to removing oxidation…

Filtering Detergent in Industrial Ultrasonic Cleaning System
Q: Is there a benefit to filtering the rinse water or the detergent solution in an ultrasonic system? Is it even advisable? If so, can you recommend a filter size (10 micron) when using Alconox detergent? This is for a new bath setup in a new piece of equipment.
A: My short answer would be, it cannot hurt but would likely be of limited assistance.
Water Spots on Stainless? Improve Blowing Process
Q. White spots appear on our stainless steel parts the day after cleaning with Alconox. Right after we clean them, they are dry and visually clean. So, is this next-day residue from the Alconox detergent? If not, can you tell us why this is happening? A. It is fairly unlikely that visually clean parts have Alconox residues suddenly appearing the next day. In addition to Alconox being free rinsing, any residue that did not get rinsed for whatever reason, would be visible fairly immediately.
Most people in similar situations, even though the parts appear “dry and visually clean,” find that the spots are from water.
Cleaning Carbon Deposit Swirls On Alumina Parts
Q. Our parts, made of 99.5% alumina, have carbon deposits that show up after our brazing process. We do not use a flux for our ceramic parts; we high-temp fire a moly/manganese painted paste onto the ceramic. The part is then sent out for nickel plating to prevent corrosion of the moly manganese metallization areas. The next step is our brazing.
We are not seeing any spots on the parts before brazing, but as we continue through 5 brazing cycles and braze in a hydrogen/Nitrogen furnace with the cusil braze rings, we see black spots forming that show up as high-carbon deposits with the SEM data…
