soap and water, rubbing alcohol (optional: hydrogen peroxide), then ointment or if you do not have that available petroleum jelly
when it starts to itch during the healing stage I use anti itch lotion / eczema relief lotion or more ointment/petroleum jelly
edit: also to be even more sanitary and prevent infection and things such as Tetanus, MRSA, or a Staph infection
always make sure to use brand new tools that have been sterilized before use or keep up with how long you've been using your tools and make sure to thoroughly sanitize them
