Cleaning Electronic Parts for High-Voltage Applications
Q. How can I clean electronic parts and assemblies for extremely high-resistance and/or high-voltage applications?
A. I recommend you clean with the product Detergent 8. Detergent 8 is an ion-free cleaner that cannot leave a conductive detergent residue. You use Detergent 8 at a 2-5% dilution (2.5 oz/gal to 6.5 oz/gal) depending on how you are using it. For soaking use 5%, for ultrasonic tanks use 3% and for pressure spray washing use 2%. Rinse thoroughly with deionized water after cleaning.
Air Shipping Citranox
Q. I want to air ship a sample of Citranox to one of our vendors for evaluation. Are there any shipping limitations on Citranox?
A. Citranox is a non-hazardous detergent that has no shipping restrictions or limitations.
Electronics Cleaning – Kovar

A. Kovar is made up of 29% nickel, 17% cobalt, .2% silicon, .3% manganese and 53.5% iron. Kovar is known for its low coefficient of thermal expansion. Kovar end uses are usually glass sealing in the electronics industry.
Aluminum Eletrostatic Filter Soak
Q. I am looking for a soak cleaner for my aluminum electrostatic filter in my air purifier.
A. I recommend you soak in a warm 2% solution of Citranox. Citranox will not attack aluminum and is an effective soaking detergent. Download the Citranox MSDS or Technical Bulletin.

Electronics Cleaner – Circuit Boards w/ Alodine
A customer needed to clean an assembly of a printed circuit board which had been sweat soldered to an aluminum plate/heatsink/carrier. The company needed a cleaner that would not attack the Alodine coated aluminum backside or the gold pockets or solder reflowed surface of the circuit board.
Unfortunately, the current cleaner was slightly base ph 9+ and the water slightly alkaline as well coming in at a ph of 8.0. This, along with other factors, caused staining, darkening and spotty discoloration of the 6061 Alodine coated (chemical conversion coating) aluminum parts.
