Let customers speak for us
from 29 reviewsI'd used antiperspirants for years without giving it much thought, they worked and that's what mattered. But as the years went by, I'm 71 now, my underarms started to rebel against the products I'd been using so figured it was a matter of body chemistry and my aging body so started trying other products that I thought might be gentler on my skin. They would work for a few weeks or a few months and then the burning or itching or blistering would start up again. Pretty sure I've tried every brand out there and was starting to get worried - I live in AZ and it gets pretty hot here so I can't go without using something! Then I happened to see a Pit Prep ad of yours and jumped at it, and ended up buying the charcoal soap too. What a wonderful discovery this is, I wash my underarms every morning with your soap and let them dry thoroughly, then spritz on some Pit Prep and I'm good until the next morning, it hasn't failed yet. Even working outside in my yard in the sun and heat, my underarms stay fresh, that's not an exaggeration. Thank you so much! Fingers crossed that my body doesn't rebel against this too, but both of these items seem so gentle while still being very effective at what they do, so I'll be praying this is the more natural non-toxic answer I've been looking for, for so long. Thank you again Stainky's!

My first review was for the Charcoal soap so doing a copy and paste from that.........I'd used antiperspirants for years without giving it much thought, they worked and that's what mattered.

I was surprised this worked so well as a deodorant primer. Game changer!

Love this stuff. Makes natural deodorants really go the distance.

This has seriously been a game changer. Before using this product, I was using natural deodorant - many different brands - and nothing seemed to last. All of my t shirt pits smelled like stale deodorant and BO, no matter how many washings or putting baking soda on before washing. With Stainky's Pit Primer, I just spritz a couple of times under each arm, dry a few seconds, then apply my natural deodorant and no more staink! (And no, I'm not a shill for the company, just a very satisfied customer!) Thanks Stainky's!

Well this stuff just rocks. Just go ahead and buy the whole kit. Trust me. The pit mitt alone is worth like $20. The best exfoliating mitt I've ever owned (yes, I've owned a few). The charcoal & salt soap is stellar. And I haven't even gotten to the actual PIT PREP yet!!!
I've been using natural deo for years to varying degrees of effect. This definitely makes it last longer, without a doubt. One day I sprayed the pit prep and forgot to put on my actual deodorant but no one ran screaming from me. I didn't stink at all. Coulda just hurled my deo into the bin right then. But I didn't, because my natural deo smells good and I'm a sucker for all the smells (good ones). Remember: there's a big difference between a smell and a staink. Thanky, Stainky's!!

Works just as promised. The exfoliating net is extremely effective and easy to use. The soap is also an excellent product and I’m glad that I purchased the entire kit rather than just the spray.

Works! It's hard to find a non toxic deodorant that actually works for longer than a few hours at a time, but I feel so fresh and confident since using this product, and I've noticed the results get better over time. Will definitely be a return customer.

The pit prep is great- it has really increased the effectiveness of the natural deodorant products I use and has even kept me stink-free when I’ve forgotten to apply anything at all. The exfoliating mit is great- I turn it inside out and use the soft lining for a bubbly whole-body scrub. I highly recommend this product, it actually does what it says- plus you support a cool small business by shopping here!

Used for a month now and it has met my expectations. Easy to use.

You guys, you gotta try this refreshing spritz! I take a shower, I towel off, I spritz one spritz of Stainky's under each arm and I feel SO GOOD. I wear it on its own unless it's a special day in which case I let my spritz dry and then swipe a little aluminum free old spice on top of my pit prep. Seriously, I've never felt so confident about the way I smell and move through this sweaty, musky world! Please, join the club. Your new life is just one spritz away!

It smells clean and it has a hint of mint. I love how natural it is! And the scent isn’t overbearing it’s mild. 10 out of 10 would totally recommend.
