Stains in the Bottom of a Pressure Cooker

I have an older Presto pressure cooker and it is pitted in the bottom and stained badly. I got it at yard sale today. The stains in the bottom look black but also appear to be pitted. Is it possible to remove them? I have lemon juice, baking soda, and vinegar with water inside now soaking. Any help will be appreciated.

I use ammonia for cleaning burnt on messes. Like the stove inserts under the burners. I place them in double or triple plastic store bags then pour a bottle of ammonia on them, tie the bag and let sit overnight. When I open the bag, CAREFULLY, not to breathe the ammonia, I remove the parts and begin using a scouring pad which easily removes the mess.

this might work for the pressure cooker, pour in some ammonia, put the lid on, without the rubber gasket and let sit. As for it being pitted, I do not know if it is safe to use, or not, but after cleaning, I would take a toothpick and try to remove anything left in the pits, just to see if it can be removed.

If your pressure cooker is made of heavy aluminum (mine is !) you can try putting enough water in the pan to cover the darkened areas.....then add 1 or 2 teaspoons of cream of tartar. Heat this to a simmer and see if the dark stain disappears after 10 minutes or so. This is how I used to clean and shine up the inside of an old aluminum pan my mother had.

There is a product that is sold in Dollar General Stores called "The Works" bathroom cleaner. Apply just enough to cover the bottom of the pot, and a little hot water and let it soak for a while. This product is also great at removing lime scale buildup from glass vases and ceramic flower pots.

Simple solution...put onion skin (2-3 layers including the outermost one), add water and heat the cooker and let the water boil for 20-30 minutes then you can just scrub it off easily.
