If you need to clean and whiten plastic, you can use a mixture of hydrogen peroxide and baking soda. This simple product cleans and lightens plastic well and does not scratch it.

The freezer should also be disinfected, especially if you store meat in it. Chlorhexidine is excellent for this purpose. You only treat the plastic with it and let it dry.

And finally, to prevent the freezer from freezing less, we lubricate the dry plastic with a thin layer of glycerin after all interventions. Ready!
