4 Tips To Take Care of Your Flashlight

A flashlight is such a handy thing to have in your house, your office, your purse or your car’s dashboard. You may not need it for everyday use, but you never know when you might just need it.

It does help to have one for those emergency times. It is not just enough to buy a flashlight but you should also take good care of it to ensure that it functions for the longest time possible else you will have to keep buying new torches all the time simply because you were not keen on taking good care of your first flashlight.

If you do not take care of your flashlight well it will start to corrode and once it corrodes it will destroy the wiring and stop functioning. Taking care of your flashlight involves four steps which, though seem technical, are quite easy.

These are: cleaning, replacing broken parts, protecting parts and lubricating.

1. Cleaning Your Flashlight

To begin with, clean the outside of your flashlight. This is quite simple and straightforward. For the best results use an alcohol pad and a microfiber fabric or a terry cloth.


  • To clean off, hard stains use a bristle brush such an old hard toothbrush. Ensure that you remove all the grease on the flashlight by rubbing gently to avoid scratching the flashlight.
  • Once you are done with the body, clean the lens. Be very careful with the lens as they are very delicate but very easy to clean. Simply wipe off the dirt with the terry cloth and it will be as good as new.
  • Next you will need to clean the inside of your flashlight. To clean the inside, you will have to take the flashlight apart. Start with the easy part such as the batteries. Use the terry cloth dubbed in a bit of alcohol and clean all the slime.
  • Check the threads in the flashlight and if they have any grit they will need to be cleaned otherwise the grit especially on metal torches will make it hard to remove the threaded parts whenever necessary. Use the toothbrush to remove ethe grit. Be gentle and careful not to damage the O-rings near the threads. If you think you might damage them, you can remove the O-rings first. To clean the battery contact, you can use DeoxIT as a professional battery contacts cleaner.

2. Replacing Broken Parts

  • The first thing you need to do is to check on the O-Rings. O-Rings are very important parts of a flashlight as they protect your flashlight against water and dirt. Check to see if they are all in good condition and they are not broken or dry. If they are broken then you will have to replace them immediately. If it is just dryness then don’t worry all you need is to lubricate them.
  • To replace the O-Rings check if your flashlight manufacturer sells them and buy them from the manufacturer instead of a different dealer. This way you are assured of getting the correct size for your flashlight.

3. Protecting Flashlight Parts

The other important part of maintaining a flashlight is protecting its parts from corrosion. Most parts that corrode are the battery contacts. So if they are not already corroded you will have to protect them from future corrosion.


  • To do this use DeoxIt Gold a product specifically manufactured to protect flashlight threads, springs, and the spots where the battery touches the torch from corrosion. There is a DeoxIT brand that is like a pencil. Buy that one as it is easy to use especially on the threads.

4. Lubricating Your Flashlight

The final step in maintaining your flashlight is lubricating it, you can use Silicone Grease 2.0 oz. Jar.

This step is important as it keeps your O-Rings from drying out and it ensures that springs move around smoothly as intended preventing them from breaking. There are different flashlight lubricants in the market, but the best are those that have silicone or those that contain Teflon. Some of the best brands include Super Lube, Nano-oil, Nyogel, and Kyrytox. Silicone grease lubes are especially good on plastic torches while Teflon ones are good for metal torches. You do not have to go for expensive lubricants just to be sure of good results. A lubricant such as Super Lube is cheap and readily available and is one of the best flashlights lubes in the market.


  • As mentioned, there are several parts that will need to be lubricated. First start with the threads. Lubricate with a thin layer of lube. Do not cake it with lube, a thin layer simply to coat the threads will do just fine.
  • Next lubricate the O-Rings. The amount of lube to use on O-Rings will be determined by how you use the torch. If you use your torch underwater a lot then you should use a thick layer of lubricant. For this use a silicone grease lube as it will not wash away easily as the Super Lube with Teflon does. If your torch, on the other hand, is not exposed to water then a thin layer of Super Lube or any other Teflon based lube will be good for your flashlight.
  • Once you are done cleaning and lubricating all the parts, and you are sure that any broken parts have been replaced, put the parts back together carefully and screw then into place. Now you are all done with cleaning and maintaining your flashlight. Repeat this process at least every three months. Lubrication does not necessarily need to be done so often, but you can use your judgment to decide when it is necessary. However, ensure that you lubricate your flashlight at least once every year.
