RCA SC-2 Clean

The Standard Clean 2 (SC-2) solution of Hydrochloric acid and hydrogen peroxide removes idual heavy metals, alkali ions, and metal hydroxides. The most commonly used ratio is apparently 6:1:1; we use 4:1:1. The reaction takes place at a temperature of 75C in a teflon carrier within a fused quartz bath to avoid contamination from ordinary glass.
