The Shaare Rahamim Haggada

Chapter 8: Alphabetical List of Utensils

Below, listed alphabetically, are various kitchen utensils and household items and the kashering method needed to be done to make them permissible on Pesah. 

Baby bottles
a) If hot hametz was poured into it, then Method C, Irui, is necessary.
b) If the bottle was warmed in a microwave, then Method B, Hagalah, is necessary.

Baking Pans
Theoretically, they must be kashered through Method A, Libun, however, since direct contact with a flame will ruin them, they should be locked away for Pesah and new ones should be bought for Pesah use.

Barbecue grates and grills
Kashered through Method A, Libun.

Beer bottles
Kashered through Method D, Kavush.

Blenders
a) If hametz was blended with sharp spices, then Method B, Hagalah, is required. b) If hot hametz was poured into it, then Method C, Irui, is necessary.

Braces
Should be washed very well (for biteplate, see Dentures

Broiler Pan
Kashered through Libun.

Chairs
 Must be cleaned and wiped, and places that are not accessible should be taped over

China
Cannot be kashered and should be locked away for Pesah.

Coffee Grinder
If it was only used for non-hametz coffee, then it may be washed and rinsed in cold water.  However, if it was used for anything else that might have been hametz (i.e., coffee substitute made of roasted wheat), the blades must be kashered through Method B, Hagalah.

Countertops
Kashered through Method C, Irui or must be covered well. (If they will be ruined by the hot water, then they should be scrubbed very well and covered.)

Crystal
The same law as glass, must be cleaned well and is then permissible.

Cups 
Kashered according to the usage of the cup:
(a) If hot hametz was poured directly into it then it is kashered through Method C, Irui.
(b) If it was used directly over the fire or microwave, it is kashered through  Method B, Hagalah.

Dentures
Can be made kosher for Pesah through Method C, Irui.  However, if they will be ruined by boiling water, then they should only be cleaned well and rinsed in cold water.

Dishwasher
Must be thoroughly cleaned of any trace of food; then it must not be used for twentyfour hours; finally, while empty, it must go through one complete cycle, using hot water and soap.

Earthenware
If used for hot food, it cannot be kashered and must be locked away for Pesah.  If cold hametz was soaking in it for twenty-four hours, it can be kashered through Method D, Kavush.

Electric hot plates
If hametz spilled on it when the plate was hot, it needs Hagalah.  Since this is not possible, the only solution is to cover it well with heavy duty aluminum foil.

Enamel pots
Kashered through Method B, Hagalah, preferably three times.

Forks
Kashered through Method B, Hagalah.

Formica
Countertops or tabletops made of formica are kashered through Method C, Irui; however, if it will ruin them, then it should be thoroughly cleaned and covered well.

Microwaves
