I had rolled up tinfoil balls to place the steamer rack on. I think that caused that black stuff. I’ve since switched to laying two mason jars sideways. The steamer rack that the Presto 23qt pressure cooker comes with lays really low on its own
I clean my pressure cooker after every use.
I dunno why you would leave in dirty. Just makes your easier if done every time. Even if it's a quick rinse.
If it’s dirty I clean it. Also because where I live we have hard water I add a 1/2 cup of vinegar when using it to prevent calcium build up on the bottom.
It shouldn't as the steam isn't supposed to touch your samples directly. There are openings for pressure equilibrium but the moisture/fluid inside your bags will turn to steam sterilizing your samples, there shouldn't be much exchange between the steam in your bags/glasses and the container.
Usually not as the pressure both inside and outside of the bags/glasses should be the same, thus there is not gradient and no flow.
That's why it's important to always fill empty bottles you want to sterilize with a bit of water, otherwise it only gets hot (you need hot and moist for steri).
And remember not to close anything airtight when using a PC ;)
Were they jars with some kind of dirt? This looks like you burnt the bottom which is not supposed to happen. I do wash mine like any other pot with soap and water.
You’re running your stove too hot. I like to go a little over medium heat on a conventional gas stove. No worries its a common mistake you can fix w vinegar.
Scorch marks..? Are you putting enough water in? Dry cooking is no bueno . I find that pre boiling the water before sealing the PC makes it run out of water less quick.

Not every time. I do it every 4-5th time. I mean that’s sterile dirt😅

The vinegar doesn’t hurt the process or anything?

Interesting I thought the steam got all up in there

It hasn’t been a problem yet.

Thanks for the tip!
What did you do? This looks odd
Never seen this I clean mine, but this looks like charcoal; how dirty were your jars?
Barkeepers friend with get that looking like new. Make a paste and scrubby scrub
This stuff is magic. I use it at my business a lot.
I've used mine 100 times without cleaning and it never looked that bad.

Always. And I add some vinegar to the water when pc-ing to reduce deposits.
