Moist Heat

• 1). Place the glass jar lids in a dishwasher at its highest setting or hand wash them in very hot water using lots of soap.
  
  
• 2). Washing your glass lids in the dishwasher or by hand will certainly sanitize them, but if you want them to be completely sterilized by moist heat, place them in boiling water for upwards of ten minutes.
  
  
• 3). Pressure cookers may also be used to sanitize items using moist heat. Place glass jars above the water in the bottom of the pressure cooker, and the rising steam will sterilize them.
  
  
• 4). Let the lids sit in the pressure cooker for 30 minutes after it begins to let off steam.
  
  
• 5). Remove the glass jar lids from the pressure cooker and let them cool before using them.
  
  

Dry Heat

• 1). Place glass jar lids on a baking sheet with a lip, and insert them into an oven.
  
  
• 2). Set the oven at 250 degrees Fahrenheit. Leave the lids in the oven for at least 30 minutes after the oven reaches this temperature.
  
  
• 3). Cool the lids slowly to prevent cracking. Treat glass sanitized with dry heat with care, as it is more fragile than glass sanitized in other ways.
  
  
• 4). Wrap glass lids in foil to prevent contamination. This method will keep them sterile until it is time to use them.
  
  
• 5). Dry heat may be used alone or in conjunction with moist heat. Sanitize the jar lids with moist heat first and then sterilize them with dry heat.
  
  

Chemicals and Natural Substances

• 1). Using alcohol is another way to sanitize glass jar lids. Mix it with water so that it composes 70 to 80 percent of the mixture. For example, each gallon of water should contain between 89 and 102 fluid ounces of alcohol.
  
  
• 2). Spray the lids with alcohol or soak them in it. Alcohol evaporates quickly, so there is no need to rinse anything sterilized with it. Isopropyl alcohol is the best kind for sanitizing glass and may be bought at nearly any drugstore. This method may be used on lids as well as other utensils and items.
  
  
• 3). Chlorine bleach may be used to sanitize items. It should be used at a ratio of one tablespoon per gallon of water. Soak items in a bleach mixture for upwards of 20 minutes.
  
  
• 4). Hydrogen peroxide may be used in small amounts to disinfect and sanitize your glass jar lids. The mixture should contain 3 percent hydrogen peroxide and the rest water so each gallon of water should contain about 39 liquid ounces of hydrogen peroxide.
  
  
• 5). White distilled vinegar, also called acetic acid, may be used to disinfect glass jar lids. Its acidic nature kills bacteria. It does not need to be diluted at all and may be used by spraying the lids or by soaking them.
