Ruth asked: How do I get black stains out of my pressure cooker? I cooked pork chitterlings in my cooker. It left stains and soap pads don’t move it.

When various foods are cooked in a pressure cooker, they can leave a residue that becomes black and can be difficult to remove. Here are several techniques to loosen the residue with simple items found right in your home.

Onion Method

 

You Will Need:

  • Onions
  • Water
  • Stove
  • Scrubbing pads
  • Dish soap

Steps to Remove the Stains:

  1. Fill the pot with water so that it covers the stained areas. If the stains go up the entire sides of the pot, only fill it ½- ¾ full.
  2. Remove and add the outer layers (top 2-3 skins) of an onion. For larger stains, add the skins of several onions.
  3. Place the pan on the stove and cover with a lid. Do not seal the pressurized lid.
  4. Place on high heat until the water begins to boil.
  5. Allow the onions to boil in the pan for 20-30 minutes.
  6. Remove the pan from the burner and allow it to cool until the water is warm.
  7. Add soap and scrub with a scrubbing pad until the stains are removed.
  8. Repeat if necessary.

Cream of Tartar Method (for aluminum cookers)

You Will Need:

  • Cream of tartar
  • Water
  • Stove
  • Scrubbing pads

Steps to Remove the Stains:

  1. Fill the pot with water so that it covers the stained areas. If the stains go up the entire sides of the pot, only fill it ½- ¾ full.
  2. Add several teaspoons of cream of tartar to the water. Cream of tartar is an old remedy for shining up aluminum pans.
  3. Heat the pot on the stove until the water begins to simmer.
  4. After 10-15 minutes, the stains should begin to disappear.
  5. Remove from the heat source and allow the cooker to cool.
  6. Clean with dish soap as normal. If there are remaining stains, they can be cleaned away with a scrubbing pad.

Ammonia Method

You Will Need:

  • Household ammonia
  • Scrubbing pads
  • Dish soap (Bleach free only)
  • Warm water

Steps to Remove the Stains:

  1. Fill the pot with ammonia so that it covers the stained areas. If the stains go up the entire sides of the pot, only fill it ½- ¾ full.
  2. Cover the pot with a lid, but do not use the rubber seal as the ammonia may damage it.
  3. Allow the cooker to soak for several hours to overnight.
  4. Use caution when removing the lid as the fumes may be quite strong.
  5. After finished soaking, remove the ammonia and dispose of it properly.
  6. Clean the pan with dish soap and warm water, using a scrub pad to clean away tough areas.
  7. Repeat once if necessary.

Additional Tips and Advice

  • Remove the rubber seal when cleaning with chemical products to avoid damaging it.
  • Ammonia fumes can be irritating to eyes. Wear protective eyewear if needed to lessen exposure.
  • Never use soaps containing bleach to clean out a pan that has been filled with ammonia. The mixture of bleach and ammonia creates toxic fumes.
  • Some have found toilet bowl cleaners effective for removing stains. Use caution when introducing such harsh chemicals and cleaners to cooking items. If used, ensure all traces of cleaning product are removed before use.
  • If the pan is pitted or damaged, it may be time for a new pan.
