It's recommended to clean your fridge every three to four months, or at least twice a year. This will help to remove any built-up dirt and grime, as well as prevent the growth of bacteria and other contaminants that can cause food to spoil.
In addition to regular cleaning, it's also important to clean up any spills or messes in the fridge as soon as they occur. This can help to prevent the buildup of stains and odors, and keep your fridge clean and fresh.
Furthermore, it's a good idea to periodically clean the fridge's condenser coils, which are located either on the back of the fridge or underneath it. These coils help to dissipate heat, so keeping them clean can help your fridge run more efficiently. To clean the coils, simply use a coil brush or vacuum to remove any dust or debris that has accumulated on them.
Overall, cleaning your fridge regularly and promptly addressing any spills or messes can help to keep it clean and prevent the growth of bacteria and other contaminants. By cleaning your fridge on a regular basis, you can keep it running efficiently and prolong the freshness of your food.
