How to clean guardian service ware
Cleaning Guardian Service (mes mains propres image by Francis Lempérière from

Guardian Service Ware, thick aluminium cookware, was first introduced in the 1930s, flourished in the 1940s, and was discontinued in the mid-1950s. First touted as "waterless" cookware, the earliest pots and pans had aluminium lids which were later replaced with glass covers, but the design and utility of the cookware is still highly valued by both cooks and collectors. It is as usable today as it was 60 or 70 years ago, and while it is nearly indestructible, it deserves to be kept clean and polished.

  1. 1

    Scrub the inside and outside of a Guardian Service pan with a soapy steel wool pad promptly after each use. Although these aluminium cooking utensils tend to discolour after use, light rubbing usually will remove any darkening from the smooth inside surface. The pebbly outer surface of Guardian Service utensils may require extra attention to burnt-on or baked-on spills.

  2. 2

    Simmer an acid solution in a Guardian Service pot after an alkaline food or boiling water has discoloured it. Prepare a solution of 2 to 3 tsp of citrus juice, pineapple juice, white vinegar or cream of tarter to each quart of water. Fill the utensil to a line above the stain and simmer for 15 or more minutes or until the discolouration can be polished off with a steel wool pad.

  3. 3

    Clean your Guardian Ware with speciality Guardian Ware cleaning products or product kits, which can be purchased from some online merchants, online auctions, or antique stores. These products are specifically designed to clean Guardian cookware and while not necessary are worth trying.

Tips and warnings

  • Guardian Service Ware is widely available in stores and on the Internet; the prices vary widely, but it is much more expensive in 2010 than it was in 1950 despite the fact that the glass lids have not survived as well as the original aluminium covers. Most dealers offer either original glass lids or replacements made for Guardian cookware. The styles of Guardian Service Ware are among the most innovative ever manufactured in the United States and include the famous "three on one burner" trio of pans.
  • While the majority of Guardian Service Ware available is in good, if not excellent condition, there are some pots and pans available which are deeply pitted and scratched. Aluminium cookware in that condition is not recommended for use as cookware, and should be discarded or used for other purposes.
