Alternatives are required due to legislation and environmental and health issues. Solvent cleaning has been tried but is not satisfactory.
Clean enough to warrant flawless soldering of electronic components in oven.

Alloy is very susceptible to chemicals, mechanical forces and oxidation. The extremely small dimensions of the parts, and the density of the alloy, make it hard to get the cleaner to penetrate between the parts, but more difficult to get fluid out.
Using the laboratory database of past testing and vendor supplied information, two lists were generated based on the specific client information.
