I've had a couple of homeruns with skin infections. Eucalyptus oil worked for 
one but not
the second one. Coconut oil worked on the second one (Eucalyptus oil made it 
more angry).
For you that second guess the necessity of a quality distilled water because 
''it's too much 
trouble with a home distiller'' are kidding yourself if you think what you 
made/make is colloidal silver.
There are few if any ''short-cuts'' to making a quality colloidal silver. The 
generators of Ode Silver Puppy and Trem Williams (Silvergen) are my choices..
