Etching During Cleaning

Question:
My system has the following materials in it: CPVC, stainless steel, cast iron and copper; should I expect an 8% Citrajet solution to etch any of these materials?

Answer:
No etching will occur on CPVC, Stainless Steel, cast iron and copper from 8% Citrajet. Cast iron might rust in the rinse water, especially if you use hot rinse water. Use water below 120 deg F to rinse cast iron and then dry quickly.
