This is a STAIN REMOVER, the Mold KILLER is another botanical spray sold by the same company.Proper mole remediation steps are:**FULL PPE, Goggles, respirator, and suit***1. spray with the mold killer (the other bottle you buy) Let it sit2. spray with THIS STAIN REMOVER (full ppe, I'll explain more below) let sit3. spray with the other botanical smell reducer, or the original mold killer botanical to balance the stain remover and confirm no more mold will grow.4. remove all PPE after confirming all areas are free from the chemicals in the air and surfaces before letting other people in.5. rinse your whole body in a clean, untreated shower and put on clean clothes.Those are the real steps to remove mold. This is just a stain remover and the mold will likely return. Although it takes a while and looks really clean in the meantime with just this spray.NEEDS FULL PPE, Body suit, mask, eye covers, everything covered.I used to work for a mold remediation company so that's how I know the proper steps and that full PPE is needed.I got lazy and started spraying this small bottle around thinking "residential size" "small bottle" sold on amazon to anyone" so it should be fine just to spray around for the stains after cleaning, I'll just wear a fullshirt and long pants...... WRONGI had no PPE, only fully clothed and thought was being 'careful' and somehow got some of the chemical on my body. Upper left chest area and upper left back areas are effected.Exposure was almost four weeks ago and I'm still unable to wear a real shirt (only a cami with the strap up on the right side, strap down on left and half of a bra the same with the right side up only, my left side has been completely exposed for at least three weeks while my skin heals. (picture is somehow flipped, used front phone camera) this has kind of ruined my life. this whole time I have had no video calls (I'm a business owner) no in person meetings, I've been out of sight this whole time, which kind of works these days anyway.There were three solid days of screaming pain deep into my nerves on my back and front chest areas. This stuff somehow got into my pores or something, but I could feel my actual nervous system work. When my system triggered it was like stabbing electric pins traveling around up and down my spine and out to my back shoulders and back. It was soooo painful!! meanwhile my skin was blistered and all different colors. I couldn't put patches or anything on it because it was painful and I didn't want to disturb the skin (it would probably peel off at that point) so I kept dabbing water on it and would apply numbing cream a few times a day at least (I'm now down to twice a day, sometimes three and can shower every other day at least now) At this point it is still healing, there are some bad spots left, and the pain is moderate, manageable and seems to tingle/tickle/sting at this point, so slowly but surly it's getting better.The attached picture is just of my back and is about 3.5 weeks after exposure so WELL into the healing, Imagine what it used to be!!! BE CAREFULL with this, FULL PPE for your own good!!I'm a tough person and super optimistic so I got through this thinking the next day would be better, what a mistake I should have went to the hospital asap. I might be better off today if I had. So if you are exposed, don't take any chances and go to the ER ASAP. It crept up on me slowly after exposure, so SHOWER right away after use!!!!Exposure day: felt nothing, totally activeNext day: what is that little bump, did something bite me? (on my front upper chest)Next morning: husband and son say (ewww mom, what's that rash on your back?? looks gross! (started as a red blotchy rash that poked out from under my sleeveless shirt)3rd day: This stings and hurt and owe owe owe, holy crap, can't even wear a shirt... can't sleep, every movement triggers my nervous system.... and it got worse and worse for the next few days.....5th day or so - ok not as painful as yesterday, I think I'm on the mend now.... just keep applying the ointment and caring for it with water until it heals.....(still in major pain but that was the turning point and has been slightly better each day since)today is One month later (almost to the day) this picture was from about a week ago. the back part used to go from a little on the other side of my spine, all the way up to my neck, down to where my bra line should be, and all the way to my shoulder and under my pit a little bit. You can see in the picture that it's reduced a lot. the skin that is healing seems not to have a scar (I'm worried about the deeper parts but will wait till it clears out and will be using those scar reducing patches) just don't want to put anything on it yet, that stuff is actually healing pretty good on it's own, every day I wake up better and better. I just started working out again two days ago and am pushing myself to continue, but going three weeks without my normal routine has me feeling like I'm in a rut. :( not ok Hopefully soon I can wear a shirt and the rest of my bra!!!Right at this moment, it itches and burns, I'm not touching it, just water dabs with a towel and numbing ointment still. What a nightmare!! Don't wish this on ANYONE so PLEASE HEED MY WARNINGS and instructions for proper use!!This picture is after almost four weeks of healing, it was so much worse and SUPER painful. If you think this looks bad, imagine 10x worse so be CAREFUL (I was careful too, wear full PPE!!!)Also, yes, the bottles tend to decay because the chemical is too strong. This stuff will 100% leak if it's stored, this is not meant for storage. Use what you use and send the rest down the drain, rinse the bottle a few times and recycle it.If I weren't a stupid idiot about it it would be 100% product review because it really does what it's supposed and I think it's the only thing on the market and it's used by professionals too. So be professional about it! :)
