I know there are other ways of doing it but can it be safely done with heat?
I’m guessing put it in a cold oven to avoid rapid temp change and bake at 350 for an hour?
but thats based on nothing, just a guess

Maybe but why? There are so many safer, quicker, easier, less expensive ways. But the glass was hot enough to liquefy at some point so it’s possible that it can be done without shattering. I’d slosh some Iodophor or Star-San around in it myself.

Get some Starsan...

Bleach?

Most bacteria and pathogens are killed at 185 deg f. So 350 is overkill. A foreseeable issue with this method is that there could be non-organic residue left in the growler that can potentially contaminate the beer.

350 is definitely overkill, as is the length of time. If you would put it in boiling water it would take only a minute or so to sanitize.

I run mine through the dishwasher with no soap. No problems so far.

The only issue with this is that the trap in the bottom of the dishwasher can sometimes add crap to the water. Personally, I’d recommend everyone get a small thing of star san and a gallon of distilled water. Make a gallon batch of starsan in the jug the water comes in. It’ll keep virtually indefinitely. Needs to be distilled because otherwise the acid will react with water minerals are in the water. I then take the star san and put it in a spray bottle. You can spray the inside of the bottle out after cleaning and you’ll have a clean and sanitized growler. Easy enough, and no dealing with excess heat or anything.

Urine is actually quite sterile and acidic, and will kill most (if not all) living critters in the growler. All it takes is a keen eye, a quick shake, and a nice rinse with warm water and you should be good to go.

If he was going to fill the growler with Bud Light, this would be redundant,no?

John Palmer has a dry heat sterilization times posted here:

I would put the growler in before you turn the oven on and leave it in there after it’s off to minimize fast temperature changes/risk of broken glass.

I am not sure what you are doing w/ the growler but all of the cleaning solutions mentioned will sanitize rather than sterilize your growler, which is fine for most homebrew purposes. Or if you don’t want to get Star San or whatever you can rinse it out w/ white vinegar and again w/ filtered water. If you are just getting your growler filled at a pub, just clean it out as well as you can.
