SUMMARY
The discussion focuses on the effectiveness of 15% Hydrochloric acid for rust removal from mild steel pipes. While initial tests showed successful rust removal and slowed corrosion, subsequent large-scale applications revealed rapid corrosion due to residual chlorine from the acid. This chlorine contamination poses significant challenges, particularly in marine environments and automotive applications. Alternative rust removal methods, such as immersing items in molasses or using commercial rust converters that apply a phosphate coating, are also highlighted as viable options.
