What have I done wrong? (100% contamination)

Hello guys,
Coming back to this forum like I'm calling 911 for help.
This is my second grow after a successful first try: 11 jars, 0% contamination, and 45 cracker dry grams. (PF, fruiting chamber).
Now, I have tried a more courageous attempt, with more jars, and got 100% contamination. These are my conditions: -PF verm+BRF mix -cooked 90 minutes -the spore prints: alcohol wiped foil, sealed in several ziplocs. -clean syringes, cooked for 30-40 minutes. -innoc in home-made glove box with 2 hand holes -red hot needle after each jar + alcohol wipe.
Did I leave anything out? Also, what should I do with the contaminated jars? Can I just empty them out, clean them thoroughly and cook them again for longer?
Thanks guys! Peace out.

Did your jars contaminate or not germinate at all?

always sterilize your jars again, before removing the bad cakes from them.
did the contams appear where you injected the spores, or were they at random places on the cakes?

Yes, contams have appeared where the syringe injected.. :-s infected needles?

Most likely a bad print was used. It can be hard to keep a cap 100% clean before and while it drops spores. And yes, you can empty jars and re-sterilize them to be reused.

Do this!!! This is for your health and to prevent your whole living area from being contaminated. After make sure to empty them outside. I would rinse them outside also then throw them right in the dishwasher.

Do not wipe you needle with anything after you flame sterilized it. However, I doubt that this is the (main) reason.

More information please. Such high contamination rates usually occur when the spore print itself was dirty. How did you prepare your syringes?

Is it a glove box or a still air box? More info.

Try to kill whatever is inside the jar, before opening it. I PC anything that appears contaminated, especially if I see any kind of contaminant spores.
EDIT: If the contaminant occurs at the inoculation points, your print was dirty. You probably took the print and put the spores into some water, right? This way you made sure the mold spores were in every one of your syringes. That's why I always put spores onto agar... I don't know why agar seems to be so unpopular here.

i'd say it's definitely a bad syringe. i wouldn't use that one again. make a new one!
weather i made it or bought it, i always test every new syringe before i do anything serious with it. this has saved me from wasting my time and supplies on quite a few occasions.

Should I sterilize the prints? Would that kill the spores?

Yeah, that would kill the mold spores as well as the cube spores. 
You can try to germinate the spores and clean the culture on agar or just use/buy another print.

Your solution is quite simple, buy new spores. Preferably a syringe from a sponsor to insure that it's sterile.

Of course, then you're missing all the agar fun...
