Aquanox A4708 is said to rapidly clean under densely populated, low-gap PCB assemblies and is reportedly effective on all flux types, including no-clean and water-soluble residues. Is pH neutral, formulated for enhanced metal compatibility, and safe for delicate gold and aluminum bonding pads. Provides bright solder joints, even after multiple wash exposures. Comes in one, five and 55 gal. containers.
