Flux Residue Removal
Q. I am seeing a white powder around solder joints on PCBs. Is this solder flux? We use Detergent 8 for cleaning. Do you know why this is happening and how to stop or remove it?
A. There are several ways of approaching this common issue of solder flux and its removal. For example, One way to fix this problem is to lower the temperature when soldering. In another scenario, a leading aerospace manufacturer studied putting potassium silicate (10 mL in 10 L) into the Detergent 8 bath to act as an inhibitor to stop the formation of these white salts.

Replacing HCl to remove MnO2
Q. Currently using Hydrochloric Acid (HCL) to remove residual Manganese Oxide (MnO2)from glassware. Following ASTM D1721 instructions. Do you offer a cleaner that could do the same job and assist in replacing HCL and remove the MnO2?
A. Yes. Use a 2% Citranox (2.5 oz/gal or 20 mL/L) solution followed by a thorough rinse to remove Manganese Oxide from glassware. The mild organic acid chelating agents will remove MnO2 more safely than hydrochloric acid.
How can I remove a radioactive lutetium drug residue?
Q: How can I remove a radioactive lutetium drug residue? A: Lu 177 (lutetium) and other radioactive metal drug residues can be tough to remove. We recommend warm or hot 2-3% dilution of Citranox (20 – 30mL/L) followed by a thorough water rinse to clean steel, plastic and other hard surfaces to decontaminate radioactivity.
