How do you clean an infrared thermometer gun? General maintenance and cleaning can go a long way towards the longevity of your IR thermometer. However, improper cleaning techniques can damage the thermometer, even beyond repair, and utilizing the wrong utensils can have a similar effect.

It is of the utmost importance to pay close attention to details whenever you clean your infrared thermometer guns and that you take every precaution to avoid damaging the sensitive devices that make up the working components of your infrared thermometer guns.

Do You Need to Clean Your Infrared Thermometer Gun?

The short answer to this question is yes, resoundingly. This is especially true if you have used your infrared thermometer in, particularly dirty conditions recently. Infrared thermometers must be kept clean and free of dust, dirt, moisture, fog, smoke, debris and any other airborne particulates. You should avoid using your infrared thermometer in these adverse conditions if at all possible.

How to Clean an Infrared Thermometer Gun?

You should build a habit of always cleaning your infrared thermometer after it has been exposed to any conditions that may soil it. Use in any dirty, foggy, humid and dusty conditions will require immediate cleaning. No matter what the conditions, extreme care should always be taken to keep the lens completely free of debris.

Steps to clean your infrared thermometer:

  1. Dampen a soft cloth or cotton swab with water or medical alcohol. Never use soap or any other chemicals.
  2. Gently wipe the lens first and then the body of the infrared thermometer. Never submerge any part of your infrared thermometer.
  3. Allow the lens and body to try completely before storing or using the infrared thermometer.

How Often Should You Clean Infrared Thermometer Gun?

It is a very good idea to clean your infrared thermometer every six months. This is, of course, depending on use, so more or less frequency may be required due to the regularity of use. No matter what, if you ever have to use your infrared thermometer in contaminated conditions, you should clean it immediately after use.

How to Properly Store an Infrared Thermometer Gun?

Proper storage can increase the longevity of your infrared thermometer dramatically. Likewise, improper storage practices can leave it exposed to elements and accidents making it more prone to break.

Be sure to store your infrared thermometer between 40°F and 149°F (4-65°C). Be cautious of temperature fluctuations as extreme temperatures can damage the infrared thermometer even when it is in storage.

Cautions for Using Infrared Thermometer Gun

Drops and other powerful shocks can easily damage the sensitive mechanisms of your infrared thermometer. Care should always be taken to avoid any such falls and blows. Lanyards and wrist-straps are available for some units and add an extra measure of safety to your precautions.

Never leave your infrared thermometer lying around when not in use. Store it properly and safely until you are ready to utilize it again.

Additional Tips for Using Infrared Thermometer Gun Correctly

Infrared thermometers can have their readings affected by adverse conditions such as those dirty, foggy, humid, smokey and frosty conditions that require it to be cleaned after use. Be aware of these conditions as your readings may not be accurate.

Temperature changes can also affect the readings of your infrared thermometer if the ambient temperature fluctuates rapidly. Be sure to maintain a consistent ambient temperature whenever using your infrared thermometer.

Emissivity is a measure of a material’s ability to emit infrared energy. On a scale of 0.00 to 1.00, the higher an object’s emissivity the apter it is to absorb infrared energy (whether ambient or direct) and emit only its infrared energy. Most organic materials (people, animals, plants and their collective bi-products) maintain an emissivity around. 0.95. Due to this, your infrared thermometer may read inaccurately from low emissivity materials like aluminum or stainless steel.

Conversely, if a stainless steel pan is coated in organic material, like cooking oil, the emissivity will increase due to the film of organic substance coating the surface. Some infrared thermometers have adjustable emissivity settings to account for this phenomenon like the ThermoPro TP30 Digital Infrared Thermometer Gun to help you account for and offset inaccurate readings.

ThermoPro TP30 Infrared Temperature Gun, which fully adopts the Thermopile Sensor Technology to give you seamless user experience and the most accurate readings you’ll get. Boasting impressive specs of backlight display selection, 1.5 accuracy range, 12:1 Distance-Spot Ratio, 0.1-1.00 adjustable emissivity, automatic battery indicator, and a swift response time of 0.5s, you are assured of desirable measurement every time. This is why ThermoPro TP30 be outstanding!


There are materials that your infrared thermometer cannot “see-through”. Glass, liquids and other transparent objects may allow light to pass through them, but your infrared thermometer will measure the surface temperature of these objects and not the object you see beyond their surface. So if you point your infrared thermometer at an object underwater, you will receive a reading for the surface temperature of the water.


In conclusion, cleaning your infrared thermometer is one of the most important maintenance procedures you can practice. Make a habit of cleaning your infrared thermometer regularly (every six months) and always take the time to clean your infrared thermometer immediately after use in any adverse conditions.

Take care to store your infrared thermometer properly and always take the necessary precautions to avoid dropping, hitting or otherwise shocking your infrared thermometer.
