G'day Robin,

15% or 20% solutions ... standard over-the-counter ... not the fanatics' 100% Palm Island (~ ?) rip-off.

I use them straight from the bottle for most casual antiseptic / antibiotic needs ... sans pain, sans panic. I also use about 0.5% in Sorbolene as a standard wash / soap substitute ... and keep a smaller pump bottle with ~2% in Sorbolene for trouble spots.

Straight application of the 15% or 20% is fine on skin (mine, anyway!) /abrasions /scratches /shallow cuts. I have also used it at the ends of my lips for cold sore treatment ... some warming tingle, but good, quick effective treatment. I think I'd culture the 'frig before I tried to blame tea-tree for scarring. (Shades of Peter Berryman's When did we have Sourcrout [not my spelling!] ... Charlie?)

Regards,

Bob Bolton
