Before you go out in one drop! If you are sick and have horrid poops then you may need a couple drops. It’s a fresh scent and it’s absolutely amazing! It doesn’t just cover the smell it neutralizes the smell on a molecular level! Now I buy it and put a few drops in a spray bottle and add a little running alcohol and then the rest is pure water. Or you can add a couple drops, then fill a 1/4 way up your bottle with running alcohol, then another quarter way up (so it should be half filled by then) with your favorite downy softener or whichever you choose. Then top off with water and shake well to mix. Now you have your very own room deodorizer! It smells nice and the drops help to neutralize any bad odor and the alcohol you won’t smell after a minute or two and it helps to bring out the scent along with getting it to dry without any residue left behind. (Thanks to TikTok on that tip but my only addition was adding the drops) These drops are phenomenal! One of my grandsons has pancreatic insufficiency and before he was put on medication he wasn’t absorbing nutrients and it was making his poop absolutely putrid! Even the GI doctor during the colonoscopy to rule out anything else said he had never smelled anything like it in his life and he had performed thousands and thousands of them on pediatrics over the years. So that tells you how bad this kids bms were. Travel size helps too!
