For Easy Sterilizing...

i just got into brewing and at the homebrew supply store they sell a one-step sanitizer, similar to H2O2. you just dunk all your tools in it and their ready to go, completly non-toxic. like this: http://www.austinhomebrew.com/product_info.php?cPath=178_56_36&products_id=503 its a powder that uses 1 Tablespoon per gallon of water.
so is there a reason no one is using this stuff for myco work? it could make certain things a lot easier if you just had bowl of that on hand... -cleaning dozens of jars and lids quickly -cleaning syringes
as easy as bleach/water without the bad stuff.

It would help if we had a clue what the hell this substance is. Oxidizing agents are fairly proficient at subduing bacterial growth, as well as mycelia growth. But we have to know what this substance is to have a chance at an intelligent evaluation. I am very dubious that any powder mixed with water would have much of a sterilizing effect. Sanitizing is a very vague term.

well im not exaclty sure what it is but... -it works very similarly to H2O2 from what i understand -it is safe enough to use to clean brewing equipment like fermenters, which hold the booze, without giving it any flavor of toxins. -it doesnt stunt the growth of the brewers yeast. yeast=fungus.
"oxydizers=corrosion" Pris- then forget about the lids, just the jars.

I don't want to sound negative, but what brewers need to sanitize against (largely) are wild yeast (as you say, fungi) strains. Hydrogen peroxide attacks enzymes and is fairly effective against bacteria and germinating fungi. But after germinating, fungi can neutralize hydrogen peroxide without much hindrance. So I really can't see how a hydrogen peroxide like substance would be very effective for brewers. It is of benefit to mushroom cultivation after germination, because mycelia growth is unimpeded, while suppressing bacterial growth. But, as an equipment sterilization chemical, aqueous alcohol and bleach are probably much more effective. All due respect to our beer brewing gurus, however.

One step is a sanitizer not a sterilizer. It could be used for cleaning tools much like H2O2, but for much of mycology sanitizing is not good enough. Plus if yeast was placed in sanitizing solution it would be killed quickly. The fact that there is no rinse sanitizer is because only a small amount of diluted sanitizer remains in the container or on the utensils, and is diluted by 5 gallons of wort, which cause no concern of harming the yeast. It works very well in home brewing because conditions do not need to be sterile. When yeast is pitched it is in large numbers, which will definitely beat out any other contam for sugar consumption. Plus yeast output is alcohol so once fermented, it is a hard condtion for other bacteria or mold to live in. Also home brew is often times exposed to open air which unlike mycology, causes little concern of infection.

I went and looked up what One Step Sanitizer really is. It is a mineral and oxidizer bound together in powder form. When added to water, it actually forms hydrogen peroxide. It is called no rinse because unlike other brewing sanitizers, it doesn't screw with the pH, since it's not alkaline. They claim that the small amount of dissolved minerals (1 Tblspn per gallon) won't affect taste.
Since it is basically dirty hydrogen peroxide, aqueous H2O2 obviously is a better choice. As Riggidy says, this stuff will not be strong enough to sterilize, and brewers only use it on equipment that is already very clean, as a final wash. Brewing doesn't require require absolute sterility. Medically, H2O2 is called an antiseptic because it is gentle enough to be used topically. In mushroom cultivation, there is a ton of info out there already on the uses of H2O2, but 'easy sterilizing' is not one of them.
