Not to nitpick but silver DOES NOT dissolve in water. Whatever this guy's end result is by ''dissolving'' silver in his ''tap'' water has no relationship to colloidal silver.. Also, if one is plating the inside of their ''colloidal silver jar'' there is something out of whack with they're generator system....it reeks of runaway current. Folks like Ode Coyote with his SilverPuppy and Trm Williams with his Silvergen CS generator have done their homework and put out a great unit.. Also, cleaning your silver rods/strips should NOT be a trying effort. A paper towel or a soft clean cloth works well...and quit trying to make whatever ''residue'' they might leave behind is an issue...It's a NON issue unless you make it one..
