Wash pressure cooker gaskets in the dishwasher? I do.

When phosphates were removed from national and store brands of dishwasher detergent, I tried the infamous Lemi Shine and noticed black plastics like the handles on pots and pans and black santoprene dishwasher-safe steak knife handles taking on an ashy glaze. The knife handles were also becoming stiff. I switched to phosphated Bubble Bandit and within a few washes those pieces were dark black once more, and the knife handles felt as soft and grippy as when the knives were new.

Since I have replacement pressure cooker gaskets on hand, I decided it was worth the gamble and it paid off. The gaskets come out of the dishwasher as springy as when they were new with no evidence of hardening, cracking or corrosive damage, little or no oily residue and no lingering odor from the food that was just cooked, especially if onions or garlic are part of the recipe.

Now, when they come up with a 100% dishwasher-safe pressure cooker (pot, lid, gasket, regulator), I'll be the first in line.

If I am running the dishwasher when I use a pressure cooker, I put the gasket in. If not, I wash it by hand with the cooker body and cover.

Can you put a stainless pressure cooker in the dishwasher? I hate to have to handwash our Mirro.

I would say stainless is OK, but aluminum is not.

Stainless steel pressure cooker with a silicone gasket: Pot and gasket can go in the dishwasher if you use a phosphated detergent. If you've cooked legumes, you might need to polish the interior on the bottom with Barkeeper's Friend, Kleen King or Bon Ami.

Phosphate-free detergents appear to dry out plastic, silicone and rubber. Lid and regulator: hand-wash to be on the safe side because some of the safety release components might not be dishwasher-safe.
