Gentle, Effective, and So Easy to Use
This diaper rash spray has been a total game changer for us! Unlike traditional creams, this spray goes straight to the source by eliminating rash-causing germs with its naturally occurring hypochlorous acid formula. It’s incredibly gentle—no stinging, no mess, and no need to rub it in. Just spray and let it air dry. I love that it’s free from parabens, steroids, fragrances, and alcohol, making it safe for my baby’s sensitive skin and even eczema-prone areas. It’s also FSA/HSA eligible, which is a nice bonus. Each bottle lasts a long time with over 600 sprays, and it’s made in the USA. If you’re tired of the mess and irritation of traditional diaper rash creams, this spray is a must-try. It’s effective, clean, and so easy to use—definitely five stars!

Using for over 2 years! Hands down one of the best things to use. Easy, simple and effective. Spray during changes, hands, it keeps germs and any rash down and stops irritation. 10/10

Must have for kids
This stuff is AWESOME. We use it for diaper rash for our baby but also to refresh our toddler in the mornings (I’ll change him out of his overnight diaper, wipe him, and then spray with this to get him extra clean and keep him from smelling until bath time). It’s also super nice to have on hand for cuts and burns- it’s super gentle and disinfects without stinging or burning. Our son got a gnarly burn on his wrist from our fireplace and it blistered, leaving an open scab and this stuff kept it clean and helped it heal quickly and nicely! We’ve gotten three of these so far and keep them all around the house and in the car. So many uses and I love that they’re HSA/FSA eligible as well.

Amazing, please never stop making this!
Game changer!! The only time my son who is 18 months has ever gotten a diaper rash was when we ran out of this. It is so gentle and works amazing. Now everyone I know with a baby uses it too and also loves it. A diaper rash can be extremely painful- but is easily prevented. This spray very gently gets rid of all the bacteria that causes it. It’s just electrified salt water which changes the molecule into something useful! So natural. And I try to go as natural as possible with my baby. Use after every diaper change. I always wait a little for it to dry before applying any creams (not sure if that’s necessary just sharing what I do) Please buy it for your little one, it is life saving!! I cannot recommend it enough!

Recommended!
This is the best product I've ever used to prevent diaper rash. Perfect for sensitive skin, it's colorless and fragrance-free. With my older daughter, I used creams, but I didn't like the mess and having to apply them with my hands. I looked for other options for my now 2-year-old son, and this has been the best—zero mess, and it absorbs quickly. I have a subscription to receive the product every two months, but depending on usage, it has lasted me about two and a half months. He has never suffered from diaper rash. 1000% recommended!

Works well
We use this product with all of our home diaper changes. Our daughter goes to daycare during the week. We have had very little issues with diaper rash with even intermittent use of this product.

Diaper rash be gone and never return!
Won’t catch me without this. I can’t believe I didn’t know about this for my first 2 babies, but number 3 has had nearly zero diaper rashes thanks to this spray!

Gentle on the skin but really works well!
As someone who has sensitive, eczema prone skin, this spray does the trick. Especially after a work out or if I have been sweating, I just do a quick spray and I know it will kill any bacteria on my skin. I also use it to dampen my makeup brushes, and it helps keep them bacteria free between washes.
