ANTI-BACTERIAL substrate

Ive done about 40-50 small grows over the last 10 years or so. I havent been very active on the forums, but I think its time to get back into it. Ill share my limited knowledge and hopefully someone can give me a decent answer to my question.
WHAT SUBSTANCE/CHEMICAL/DRUG CAN BE USED TO MAKE A SUBSTRATE ALMOST COMPLETELY ANTI-BACTERIAL AND NOT INHIBIT FUNGI GROWTH OR FRUITING?
I have tried many things. I dont have an issue with contaminations but, it would be a lot easier if things were just sterile and antibacterial from the beginning. It would open up a lot more outdoor grows and things like that.
Things I have tried with limited degrees of success.
Commercial agar with antibacterial mixture - slow growth Tea extracts - no noticeable difference
.2% hydrogen peroxide in my humidifier(reptifogger) - Only works indoors, works very well, destroys the machine after 1000 hours - also really good for getting rid of chest colds if you inhale a few puffs, actually recommended to me by a doctor
I would like something that works outdoors that i can just mix in with the substrate and do log and basket teks etc.
Does anyone have any clue about a substance that can achieve this?

Clean spawn is the magic additive you're looking for. You don't want to make super bacteria or any kind of resistance by inappropriately using antibiotics as a preventative. It also will help you not be able to notice yourself starting to have problems. You can't fix a systemic issue if you're using something that will cover it up.
Also in hospitals that use vaporized hydrogen peroxide they work at 150-1500ppm but the safety literature puts 75ppm as critically dangerous to humans. Which means at even 10ppm it's probably still not good for you at all just not debilitating. At a concentration that doesn't cause immediate harm I would still imagine it's doing some harm. Don't breathe hydrogen peroxide your doctor is an idiot unless he pointed to compelling and peer reviewed research showing efficacy.

You can add Gentamicin Sulfate antibiotic powder to your agar to help you get that clean spawn bod is talking about.

You should only use gentamycin in extreme cases, such as a rare wild culture or something you can't replace. Like Bod said you'll end up breeding antibiotic-resistant bacteria and your problem will come back.
Clean spawn and properly prepared substrate (be it pasteurized or whatever) can be spawned outside or inside in open air.

Clean spawn is key like stated. Shit i just picked some outdoor boomers and all i did was dump some clean spawn on the ground in a shady spot, then took a couple of cow parties and put them on top and watered. 3 weeks later after a heavy rain i had mushrooms. I didn’t pasturize the shit or anything. Now the mycelium has colonized most of the shit, im expecting more soon.

There's a couple places you can get it still. I just got some premixed agar with gentamycin from that dude who wrote a bunch of mushroom books. There's a sponsor here also who has it on their website, by the gram, or a 50 mg dose. There's an eBay listing for 100 g for around $100 which would last about 12 lifetimes, lol.

Antibiotics don't help you get there. They keep you from learning really easy good technique. There's people their first post is agar grow log and canopy flushes. Imagine every kid that fell down learning how to ride a bike kept training wheels on for years. You fumble a few times then you ride forever.

I have no disagreement with you there Bod. My post above may have sounded like I am pro-antibiotic but the opposite is true. After a couple of years of doing agar "the right way", I thought I'd give the antibiotics a try with a dirty syringe that I couldn't get to germ on agar. As it turned out, the spores still did not germinate, and the bac grew as if there was no antibiotic present. I've had better luck with BRF with contaminated syringes. Tried the gentamycin once, don't plan to use it again. It's a crutch as you say, and the only legitimate use I thought would be what I had intended it for, but even then it didn't work. Indiscriminate use of antibiotics nearly killed my wife (not exaggerating) and has cost me hundreds of k's in the last five years due to the resultant health issues. So I'm about as anti-antibiotic as you can get. I was just commenting that it was still available without a prescription. As a public service announcement to all humans anywhere, if a doctor ever wants to prescribe you Clindamycin, run away as fast as you can. It is the go-to antibiotic for dentists and oral surgeons for some reason. C. difficile is resistant to it and God help you if you get an overgrowth of that in your guts. It will change your life forever, or possibly end it. Ok bye.

So clean spawn is spawn that was transferred from agar containing Gentamicin?
Or is clean spawn just really clean spawn?

No, sorry, I was being sarcastic. As everyone is saying, no need to go that far. Clean spawn is spawn w/o any contaminant.
