Discover effective methods of preserving food. SSPDaily has told you about three proven ways to prevent rust on jar lids and preserve the quality of canned food.
Use vinegar to remove rust
One of the proven ways to save canned food when lids rust is to use vinegar. Vinegar contains acid, which helps dissolve rust and makes it easier to remove. You can soak the rusty lid in vinegar for about 30 minutes. After that, gently brush or sponge the lid to remove any remaining rust.
Apply baking soda paste
Baking soda, being a mild abrasive, makes it easier to remove rust without leaving scratches on the lid. The paste can be prepared by mixing baking soda with a little water until it reaches a thick consistency. This mixture should then be applied to the rusty areas of the lid left for about 15 minutes and wiped off.
Use petroleum jelly as a rust preventative
To prevent rust from forming on jar lids and ensure the longevity of the preservation, petroleum jelly can be used as a rust preventative. You can apply a thin layer of petroleum jelly to the rim of the jar before putting the lid on. This will create a barrier between the metal lid and moisture, preventing rust from forming. It's important to remember to remove any remaining petroleum jelly before using the food.
