Kashering Oven Racks

You may kasher oven racks by putting them in a self-cleaning oven and running the self-clean cycle. Or, clean with oven cleaner and then put into a normal oven on its highest temperature for 40 minutes.

Kashering an Electric or Gas Regular Oven
To kasher an oven that is not self-cleaning, you must:
  • Remove any deposits on the walls, racks, and window.
    Note If there are stains or deposits, you must clean them off or burn them off. If the stains or deposits do not come off after two cycles of using strong oven cleaner such as Easy Off, the oven is considered sufficiently clean.
  • Turn the oven on to its maximum temperature for 40 minutes.
    Note Self-cleaning ovens attain a higher maximum temperature than do non-self-cleaning ovens.
Kashering an Electric or Gas Self-Cleaning Oven
To kasher a self-cleaning electric or gas oven, you do not need to clean it first. Just run the self-clean cycle.
Kashering a Grill
Make a grill red hot to kasher it.
Kashering a Dishwasher from Dairy to Meat, or Vice Versa
You may not kasher a dishwasher (even if it is stainless steel) from dairy to meat, or vice versa, in order to use the dishwasher for dairy and for meat utensils, even sequentially.
Kashering a Dishwasher from Non-Kosher to Kosher
Dishwashers may generally not be kashered except when made of stainless steel (and have no non-kasherable materials inside, such as plastic, silicone, or rubber).
Note If the racks are not stainless steel or if they are coated with plastic or other substances, they may not be kashered.
Kashering a Clean Electric Stove
To kasher a clean electric stove, turn the burners on to the highest setting until the burner glows red (this is easier to see at night) or until a piece of paper will burn on it (the paper does not need to burst into flame).
 
Kashering a Gas Stove
To kasher a gas stove:
  • Remove the burner grates,
  • Clean off any deposits,
  • Place the grates on a clean surface inside the oven, and
  • Heat the grates to the oven's maximum temperature for 40 minutes.

Passover: Kashering an Oven: Cleaning
To determine whether an oven is clean: 
If there are black or brown spots, scratch them:
  • If the substance crumbles, the spots are OK.
  • If the spots do not crumble, consider the oven NOT clean.
Note If you use the oven's self-clean cycle, you do not need to remove the hard deposits from the oven before kashering.
If the oven is not self-cleaning, you must remove (clean off or burn off) any deposits on the walls, racks, and window. If the stains or deposits do not come off after two cycles of using a strong oven cleaner such as Easy Off, the oven is considered sufficiently clean. Weaker oven cleaners that do not remove deposits may not be relied on.
Passover: Kashering an Oven
To kasher an oven for Passover:
  • Clean it completely, including any hard deposits, and
  • Heat the oven for 40 minutes at its highest temperature.
Passover: Kashering Pots and Utensils To Change from Milk to Meat (or vice versa)
You may make certain utensils kosher for Passover if they were chametz or non-kosher. For a list of materials that can be kashered, see the sections entitled "Items/Materials that Can Be Kashered" and "Items/Materials that Cannot Be Kashered" here: Introduction to Food Nullification: Utensils (Kashering).
Note You may not change utensils that are already kosher directly from milk to meat or meat to milk. Rather, you must:
  • First make the utensil non-kosher (or chametz), and then
  • Kasher it.
Once kashered, the utensil will usually be neutral/pareve as far as gender and you may choose to make it dairy or meat.
