Put some water on to boil and set the muriatic acid in a glass container down in the water. I do this in an old electric fryer. I wait about 15 minutes before etching. It will etch a blade in about 60 seconds, after etching buff it then hit with the last grit paper that was used when you sanded. If its not as deep as you want degrease and go in the acid again. I am new at this so I am going to try some pics this way.
