Using Star San 1

I searched a bit and the most recent post I could find was from a couple years ago. Hopefully more people have experimented since them.
Anybody out there using Star San in their inoculation/G2G/laboratory rooms? If so, How did it compare to bleach or iso?
I brew beer and have plenty of Star San on hand. It is gentle on the lungs and eyes so it would be great to be able to start using it with confidence. My clean room is air tight and gets pretty hot and humid when I work so I have to wear a respirator and goggles from the bleach/iso fumes when I work.
Thanks

Never heard of the stuff, but as a fellow brewer im guessing its paracetic acid/peroxide based ?
Not a bad idea actually, i fucking hate the smell of iso or denatured ethanol and bleach is straight up poison
Most of the time i just use food grade 95% alcohol for desinfection, a little more expensive but a bottle lasts long enough and leaves a nice rummy smell

Star San sucks even for brewing. Use peroxyacetic sanitizer for brewing. Use 70% alcohol or 1:10 bottle strength bleach and water. Star San is phosphoric based its garbage
Also thoraxx don't use 95% 70% is a better sanitizer than 90+% You can buy 91% and dilute it to 70% to use as a disinfectant

Thanks for all the replies so far but it doesn't seem like there has been anyone on here that has used Star San for mushroom cultivation.
I've never had a contamination issue in any of my brews...outside of a kiwi wheat I did when I was a brand new home brewer. Maybe it's because I'm doing small scale home brewing(5-20 gallons a run), but I haven't seen any evidence that star san doesn't do what it is advertised to.
How about using the peroxyacetic sanitizer in place of bleach or iso? Remember, my goal is to find something that doesn't give off the harmful fumes that bleach and alcohol do.

It's all relative. Star San is phosphoric its a shit sanitizer its alright for beer since only a few bacteria can spoil it and star Sam takes care of them. Peroxyacetic is better but has fumes, and bleach and alcohol too. Regardless they're all sanitizer not sterilizer so your techniques are 100x more important

Hey all...soooo for the record i have tried a few times but it all failed... got the cobs hard and mean green(both light and dark lol) after a h2o2 blast ... like the teacher said it is pretty shitty as well ( ive got black mold in my brew jugs filled with starsan.. twice)... i would love to say it was a bad casing mineral mix and PH level that killed me (it did f*#K things.. forgot my gypsum and OSF ) maybe even a impatient peak or two.. but that black mold in my jugs man... I don't know ..i do know trichs love a low ph so a acid kinda sounds bad
I may try again.. ill keep you posted but dont hold your breath.. it was a lot of time,effort and materiel wasted.. like people say its a one in a million chance to get green hay (not our yellow straw) going in a bulk ..so its best to stick to the books
i have gotten timothy hay from Walmart with aspen bedding in a mono tub to work but thats a different story(it was easier then the starsan trial)....(ziplock tub with a old pc fan sealed on the outside with rtv silicone to pull old air out and new air in with a cloth against it on the oustside to keep bugs out when off with polyfill holes in the tub for filtering incoming air) it did last longer then the jugs...very long.. sadly its recycled pushing flowers and mushrooms still.. should of waited.. or turned my ac off...heating pad would of been nice.. oh well got a couple months of being very lazy (with that anyway lol)

soooo starsan needs a PH balance of 2-2.5 to be effective for only bacterial washes.. not molds or yeast, leaving you open for for mold spores to wake up in that acidic environment with a rinse or no rinse compared to the brewing environment due to is high sugar needed for wines,etc...(i make a mean spiced meaded cider lol). your ISO91% is slightly alkaline too (7.33) and kills just about everything( i dont like bleach too much but its very alkaline as well and kills) .... i do believe they use this at taco bell and Starbucks for cleaning utensils and surfaces but there used with other chemicals ... but maybe its not even a good wash or pre-ISO wash to even save on dish soap due to the low PH ( soap is alkaline(high PH) too)
stick to soap, water and ISO 70-91% alcohol or 1:10 bleach/water mix if a must
leave starstan for brewing drinks.......... and maybe a hydroponic slime /bacterial problem..worked great for my homemade tomato cloner issues ...haha yes it did

Yeast is acid washed to ph 2-2.5 with 10-25% phosphoric food grade(usl) its not a great sanitizer its mild in action
