In the last week I've made 10 batches of peacock swirl soap for a friend's wedding so I've used many squirt bottles of batter. I've found it's easiest to rinse the batter out as soon as I'm done with the batch but wondered how to avoid putting it down my drains. I decided to pour the rinse water into an empty gallon water jug. I now have two gallon jugs filled with soap batter water. Here's my question: do I seal up the jugs and put them into the trash or is it okay to dump out into an unused area of my property? I'd guess each bottle had about an ounce of batter left in the bottle then I filled each bottle twice with hot tap water to get all the batter out. Is it safe to dump in the natural vegetation or should I just seal and put it out for normal trash collection?
