Clean refrigerator coil once in a while to keep up the energy efficiency

The efficiency of your refrigerator goes down because of dust build-up on the condenser coil. So, these coils need to be cleaned once in a while to keep up the refrigeration efficiency.

Safety first

Before you clean the coil, fully disconnect the fridge from all power sources. Disconnect all lines including any water supply pipes. Move the fridge to a secure location for easier cleaning.

Locate the condenser coil

In modern refrigerators, this is underneath the refrigerator. In older refrigerators, the coil is on the back. Sometimes the coil is located inside a panel. So, you might have to remove the panel in order to access the coil. Make sure you read the refrigerator’s maintenance manual to locate the condenser coils. Use a flashlight to locate the coil and dust.

Use a refrigerator coil brush

You can also use a paintbrush to clean the coil. Using a refrigerator coil brush makes this cleaning easier. These are long brushes that can penetrate well inside the coil and gives a good clean.

Vacuum the coil and fan

Once the coil is brushed, do a vacuum to remove any visible dust particles. Take care not to break any parts while brushing or vacuuming the coil. Vacuum the refrigerator fan too if that’s accessible. There might be dust accumulated on the fan blades. Give it a good vacuum and you are done!

Note: If you are not sure how to clean the refrigerator coil, it is better to approach a professional who can do this for you. Make sure you clean this coil at least once a year to keep your fridge running at full efficiency.

Use isopropyl rubbing alcohol for cleaning electronic devices

Isopropyl rubbing alcohol (also called as IPA or Isopropanol) is a great hard surface cleaner with a high evaporation rate. It has a lot of applications around your home and office.

Why use isopropyl rubbing alcohol for electronics?
As rubbing alcohol is surface friendly, it will not cause any damage to your electronics. It is extensively used in the electronics industry for cleaning printed circuit board components, computer screens, displays, stencils, fiber optics, cables, keypads, electrical contacts, and connectors.

Things you can clean with isopropyl rubbing alcohol:
Use it to clean your cell phones, tablets, mouse, keyboard, and all other electronic components.

You can also use it to remove the thermal paste from the CPU fan, flux paste from motherboards, printer ink, dirt build-up on electronics and other components.

Isopropyl alcohol is safe for most plastics, seals, and ceramics. It effectively removes greases, oils, and flux without adding additional residues to contacts, relays, and circuit boards connectors.

Isopropyl rubbing alcohol as an all-purpose cleaner. It is completely miscible in water. To use it as a general multi-purpose cleaner, just mix it with the right amount of water and fill it in a spray bottle. You can use it as a sanitizer. It disinfects, and kills all the bacteria!

Note: Alcohol is flammable so use it with caution. Always read labels, warnings, and instructions before using chemical cleaning agents.

Remove batteries from electronics before storing them away

Most of the electronics are subjected to corrosion due to their leaking batteries. I am sure you have all seen corrosion of battery compartments at some point in your lifetime.

It is always better to know the different types of batteries used in your devices. Some types of batteries do leak. Rechargeable batteries like NiMH, NiCd and non-rechargeable batteries like alkaline batteries leak as well.

So, if you are not frequently using these battery-powered devices, do store them separate with batteries removed.
