Hello! It’s been a minute! Life is nuts but I’m blessed to have just gotten back from a Hawaiian vacation! We’ve been planning it for months and it was so needed. I couldn’t leave the Pacific without some ocean water, which I fully intend to use to make some soap. So, question (even though it might be a dumb one): Does anyone have any guidance on the best time/temp to boil it? I need to kill any germies but also don’t want to overconcentrate the salt. Thoughts?
