Since you're using it as a pressure canner, you can go ahead and keep using it. Clean it if you have to but it will work fine as is. The deposits and discoloration will not effect the food in the jars.

I don't think pitting is an issue.

There is no need to switch to stainless steel.

Scrubbing

Try vinegar and baking soda. Make a paste from it and scrub with that. Or a paste made from vinegar and coarse salt might work, too.

Don't salt and acid corrode aluminum?

Well, the original message said that the owner's manual recommended vinegar, and this is just a scrub anyway, not meant to be left on there so, no, I don't think it would do any harm. The salt is just for abrasion. Obviously you can use salt in an aluminum pressure cooker or else how could you cook anything worth eating? So, no, I don't see any harm there either.

My steam canner looks like that. I agree with Andy, your PC is fine, and there is no need to replace it. The deposits are cosmetic. If you're canning jars, it won't hurt anything. Vinegar and baking soda may work if you're still concerned, I've resurrected several old aluminum pans by boiling a mixture of that in them.

If it fits, mine goes for a ride in the dishwasher.

Don't worry about it a bit. When you begin canning, use a cup of vinegar in the water that you put in the bottom of the canner.

The discoloration and the little spots are not dangerous, just unattractive. The vinegar in the canning water will probably get rid of both, and will keep your jars sparkly, with no calcium deposits to wipe off.

Signed, the lady who has been using aluminum pressure cookers for 40 years. I started when I was 2. :)

Just wondering what kind of pressure cooker costs so much money? Is this a commercial cooker? I have been using an aluminum 15Lb. pressure cooker ($69) for cooking family meals for 30+ years. I have never done any canning so pardon me if I am uninformed on the subject of co$t of your cooker. ps. I clean mine with liquid dish soap and an abrasive scrubber but have never seen marks like those on mine.

But I'll bet your $69 family pressure cooker isn't the same as a 30-quart pressure canner.

oh no. As I stated I have never done any canning. I just make dinner in mine. Mostly lesser cuts of beef w/veges. I must have missed the part about it being a giant 30qt. pressure canner. Size matters. I suppose that explains the cost. Thanks.
