Washing and Sanitizing Kitchen Items

Dishes and Cooking Utensils

Wash and sanitize any dishes, pots, pans, and cooking utensils that were in contact with floodwater. Water for washing and sanitizing must be certified safe to use.

To wash and sanitize:

1. Remove detachable parts, such as blades, plastic or wooden handles, and screens.

2. Wash dishes, pots, pans, and utensils and detached parts in hot, soapy water. Use a brush, if necessary.

3. Rinse in clear water after washing.

4. Place items in a wire basket or other container and immerse them in a sanitizing solution. Santizing solution can be prepared by mixing 1 tablespoon unscented chlorine bleach in 1 gallon of warm (not hot) water. Hot water causes the bleach to dissipate, weakening the solution.

5. Air-dry dishes in a clean and sanitized dish rack. Using a dishtowel could recontaminate the dishes.

Wash cupboards and other surfaces that came in contact with floodwater with soapy water. Then rinse and wipe surfaces with a disinfecting solution. Remember, cupboards and other surfaces must be cleaned and disinfected before you can store foods, dishes, or cooking utensils in them.

Household Metals

Rust causes the most damage to flooded household metals, especially iron. Use the following treatments to remove rust.

Iron Pots, Pans, and Utensils

1. Wash with soap and water, using a stiff brush, scouring powder, or steel wool.

2. If rust remains, wipe items with an oil-saturated cloth or a commercial rust remover. If using a commercial rust remover, be sure to follow the label instructions.

3. Wash again in hot, soapy water, rinse, and dry thoroughly.

Season iron pans and utensils with a generous amount of unsalted cooking oil. Heat in a 2500 F oven for 2 or 3 hours. This will permit oil to soak into the pores of the metal. During the heating process, apply more oil as needed. When seasoning is completed, wipe off the excess oil.

Stainless Steel, Nickel- Copper Alloy, Nickel, or Chrome-Plated Metals

Wash thoroughly and polish with a fine-powdered cleanser. If hardware is broken so that base metal is exposed and rusted, wipe with kerosene. Then wash and dry the surface. Wax after each use to prevent further rusting.

Aluminum Pans and Utensils

•Wash thoroughly with hot soapy water. Scour any unpolished surfaces, such as the insides of pans, with soapy steel wool pads. However, do not scour plated aluminum surfaces because it might remove the finish.

• Sanitize in a bleach solution (1 tablespoon unscented chlorine bleach per gallon of warm, not hot, water).

• To remove dark stains from aluminum pans, fill pan with water. Add 1 tablespoon vinegar or 2 teaspoons cream of tartar for each quart of water. Boil for 10 to 15 minutes, scour with steel wool, wash with soap, rinse, and dry.

Copper and Brass

• Polish with a copper or brass polish or rub with a cloth saturated with vinegar or rub with a piece of salted lemon.

• Always wash copper thoroughly with soapy water after using acids or commercial polishes or they will retarnish rapidly.

•Wash lacquered ornamental copper in warm soapy water. Rinse with warm water and wipe dry. Do not polish. Do not soak.

NOTE: Do not use copper and brass items for food preparation or service.

Pewter

•Wash thoroughly with hot soapy water, rinse, and dry. Use a soft toothbrush to get into crevices.

• Rub on silver polish (paste or liquid, not the dip type) with a soft cloth. Use a soft toothbrush to get into crevices.

• Rinse in hot soapy water and dry.

• Check for small holes, cracked joints and dents. If the pewter needs extensive mending let a professional fix it. Small holes can be mended by cleaning the metal inside the pewter object with steel wool, then filling with pewter epoxy mender. Carefully follow label instructions.

• Replace felt or other protective materials that have separated from household decorative accessories, such as bookends, ashtrays, and candle-holders. Buy felt or protective materials in a fabric store. Glue in place with rubber cement.

Hardware

• Coat iron hardware with petroleum jelly or machine oil to prevent further rusting.

• Use stove polish on stove or similar ironwork.

Locks and Hinges

Locks and hinges, especially those made of iron, should be taken apart, wiped with kerosene, and oiled. Follow the same procedure as for iron hardware.

If it isn’t possible to remove locks or hinges, squirt a little machine oil into the bolt opening or keyhole. Work the knobs to distribute the oil. This will help prevent rusting of the springs and metal casing. (Do not use too much oil as it may drip on the wood-work, making painting difficult.)

NOTE: Only use petroleum jelly, machine oil, kerosene, or stove polish on metal surfaces that will not come in contact with food.
