Maintenance Tips for Your Flashlight

1.    Cleaning

Firstly, you need to ensure that you clean the exterior of the flashlight.  The best way of going about this is using a rag with an evaporating cleaner like alcohol. Micro fibre cloths or baby wipes also work well. For more intricate cleaning, I’d suggest you use a bristle brush or old tooth brush lightly dipped in alcohol or an evaporating cleaning solution.

You should start off by cleaning any dust, debris, dirt or grease on the exterior of the flashlight. Once that’s done, wipe the lens with a microfiber cloth. It’s important to make sure that the lens is clean. After all, that’s where the light comes from.

Once you’re done with the exterior, we need to move on to the interior. This will require you to disassemble the flashlight. You don’t need to completely take it apart. Removing the batteries is enough. If you don’t know how to, your flashlight should have come with a manual. Again, if you break your flashlight while cleaning it, head on over, they have plenty of Flashlight buyer guides to help you get straight.

Once you remove the batteries and disassemble the flashlight, for precision cleaning, we suggest that you use Q-tips dipped in an alcohol cleaning solution. You can use a small bristle brush to sweep the inside of the cylinder. Use your Q-tip clean between the flashlight’s battery contacts. It’s important to make sure that no fibres are left between the threads. You also need to ensure that the contacts are dried so they don’t corrode. While you have your flashlight disassembled, check if your springs are working fine as well. If your flashlight is already corroded, you could try a solution like MG Chemicals Nu-Trol or DeoXIt before searching for a replacement.

2.    Check, Replace and Protect

Flashlights are made up of different parts collaborating with each other. If one part fails, that could spell trouble for the other parts. So it basically works like the human body. A key part of maintenance is checking if all the parts are still working correctly. Check the lens for any scratches, dirt or grime. Replace it if it is faulty. Most flashlights, particularly the Maglite allow you to replace the bulb. If the flashlight bulb is faulty or shot, we recommend that you try to replace it before trashing the entire flashlight. I know we’re basically rehashing this point but you also need to make sure that your spring is working well. A faulty spring may impact the way the batteries sit in the flashlight. A common problem that can occur with flashlights is corrosion.

Usually corrosion occurs when you have a faulty O-ring. O-rings can be fragile components but they’re one of the most important parts of your flashlight. O-Rings are little rubber circles that keep moisture, grime and dirt of the flashlight body. They help stave off corrosion. If you notice anything wrong with the flashlight’s O-ring, it is recommended that you replace it.

To further protect your flashlight from corrosion, there are chemicals, materials and oils you can use to protect your flashlight’s metal parts from rust and corrosion. Visit your local hardware store or there are plenty of websites online to help you find the best anti-corrosion material for your flashlight.

3.    Lubricating

Lubricating your flashlight is important so it can open and close properly. Finding the right lubricant is ultra-important. Once again, I recommend that you ask the advice of your local store clerk or do your own online research to find which lubricant best suits your flashlight.

You need to start by lubricating the O-rings. Pay careful attention that you don’t cake the flashlight with any extra grease or lubricant. Lubricating the O-ring is as simple as removing it and applying the lubricant by hand. Make sure to cover the O-ring evenly.

Next, you need to use a cotton swab or Q-tip to rub some of the lubricant on the threads so that it’s easier to open and close your flashlight. Before lubricating these parts, you need to make sure that they’re clean. And that’s it!

Final Word

These quick flashlight maintenance tips should help your flashlight run smoothly whenever it’s in need. These should also help your flashlight run longer. The longer your flashlight runs, the less you’ll have to replace it and the more money you’ll save in the long run. I hope you’ve found these tips to be helpful.
