Fla ,
I can look into the tank and it looks " dirty clean "meaning no chunks of rust . I filled it with some sharp gravel that we have here in Md. and shook the bejebbies out of it , all tha tcame out was rocks and a fine brown dust . Are you saying the E-10 cleans it out better than kero or mineral spirits or should I use all three ? How about Coca Cola that I heard in another post ?
