After you’ve soaked your parts in fast etch for the 30 minuets that it suggests on the bottle, are you supposed to remove all of the sticky residue? I made sure that the part was wet for the entire 30 minuets occasionally reapplying fast etch to the metal surface that I was treating. However, after the 30 minuets, I tried to use acetone and a rag to clean the part. I found it difficult to get the part sticky-ness free and it even seemed to have some sticky residue in areas. Is that normal? I eventually gave up and just let the parts dry. They’re no longer sticky but they have a streaky look. Is this OK or should I redo the processes and do it differently?

Thanks in advance!
