What can be done to avoid ice formation in the freezer?

Place several hot water bottles in the freezer.

When the ice starts to melt and continues to flow, wipe all the walls of the freezer with a cotton ball soaked in glycerin. This will slow down future ice formation.

When loading food into the freezer, try to store it in hermetically sealed containers to prevent liquid from entering the walls of the freezer, which could lead to ice forming.

It is also necessary to check the leakproofness of the freezer door. Attach a piece of paper between the door. When it comes out, you have to change the elastic bands.
