How to Properly Clean the TENS Unit Pads

Now that we understand the significance of cleaning the TENS unit pads let’s delve into the various steps for accomplishing this:

1. Prior to each use, ensure you clean your skin. 

The most effective approach to prevent the buildup of dirt and oils on your TENS unit pads is to proactively reduce their accumulation before application. Begin by thoroughly cleansing the area of your skin where you intend to attach the pads. Use soap and water to eliminate any dirt and excess oils from the skin’s surface. This practice helps minimize the likelihood of dirt and oils adhering to the pads.

Furthermore, avoid applying lotions, oils, powders, or any skincare products to the skin where you intend to place the pads. These substances can adhere to the pads and create a sticky residue. Some manufacturers even recommend using an alcohol pad or wipe to ensure the area is thoroughly cleaned.

Before affixing the pads, make certain that your skin is completely dry. While some companies may suggest trimming excess hair to enhance pad adherence, it’s advisable not to shave immediately before a session, as this can irritate the skin. It’s essential to never apply the electrodes to broken or irritated skin.

2. Clean the pad by gently wiping it with a damp washcloth.

Cleaning TENS unit pads is a very easy and straightforward process, and all you need is water. If you notice any dirt or debris adhering to the pads, you can simply wet your hands and manually remove it. Alternatively, you can use a damp washcloth to wipe the unit pads clean.

It’s essential to avoid using a dry washcloth, as it won’t effectively remove dirt and could potentially dry out the pads. Additionally, make sure to use a washcloth, preferably one that’s lint-free and made of Microfiber, rather than paper towels. Paper towels tend to shed loose fibers that can stick to the TENS pads.

For added convenience, you can purchase TENS Pad Wipes, like the ones depicted above, specifically designed for TENS pads. These wipes function like other moistened wipes and come with a cleaner that is safe for your TENS pads. Furthermore, they won’t leave fibers on your electrode pads when you use them. You can also use these wipes on your skin before attaching the pads.

However, if you already have similar wipes at home, there’s no need to acquire these specialized TENS Pad Wipes.

3. Ensure proper storage of the pads. 

Lastly, it’s crucial to store your TENS pads properly to prevent them from becoming soiled. Typically, these pads come with their own containers, so be sure not to discard them. However, before returning them to storage, ensure they are cleaned. Additionally, there are commercially available TENS pad holders, as shown below, that can aid in organized storage.

When storing your TENS and EMS Pads, the general recommendation is to keep them at room temperature. Some brands may suggest refrigeration, but this is primarily to cool them down after use. If you do refrigerate them, make sure it’s in a frost-free refrigerator with the pads positioned sticky-side up. After cooling, return them to room temperature storage to prevent excessive drying.

If you’ve misplaced the storage liners, you can substitute them with clean wax paper, which will prevent the TENS pads from sticking to each other and accumulating dirt. Some individuals also opt to store TENS pads in ziplock bags to safeguard them against dirt and contamination.

How Frequently Should You Clean TENS EMS Pads?

The optimal practice is to clean the pads every after each use to ensure the removal of dirt before storing them. This routine maintenance can extend the lifespan of the TENS unit pads. As time goes on, these pads may begin to lose their adhesive properties. Ultimately, if you’re unable to restore their stickiness, a replacement will be necessary.

When Should You Replace Your Pads?

As mentioned previously, TENS unit pads have a finite lifespan and will eventually require replacement to ensure you continue to receive effective TENS treatment. Typically, most manufacturers recommend replacing them after approximately 30 uses or within 1-3 months, depending on usage frequency.

However, there are situations where you may need to replace the electrode pads sooner. The frequency of pad replacement depends on factors such as usage patterns, storage practices, and the type of pads you purchase. Here are some of the most common indicators that it’s time for a replacement:

The pads no longer adhere properly

A frequent reason to consider pad replacement, even with minimal use, is when they start to lose their adhesive properties. In such situations, you can try to do this to make your tens pads sticky again

While some individuals resort to taping the pads in position, not everyone finds this comfortable due to variations in tension.

The pads have dried out

Dried-up pads are highly likely to lose their adhesiveness, particularly along the edges. The low voltage emitted by TENS units can gradually lead to pad drying during use.

Certain manufacturers suggest attempting to rehydrate the pads by applying a drop of water for absorption. However, it’s important not to submerge the electrode pads, as this can lead to oversaturation.

Furthermore, improper storage practices can accelerate pad drying. It’s advisable to return them to their container or seal them in a bag to minimize moisture loss. Additionally, avoid storing them in environments with extremely high or low temperatures.

Inadequate conductivity

This is an indication that it’s time to purchase a new pad. If you wish to attempt to extend the life of your TENS unit pads and are facing conductivity issues, you can consider using electrode gel. The gel is applied to the pads to improve conductivity. Nevertheless, it’s important to note that this is a temporary solution, and you may want to get new pads that will eventually be necessary.

Experiencing a burning sensation or a change in the stimulation

When you notice any alteration in how it feels or the effectiveness of the device, it could be an indication that it’s time to replace your pads. Your TENS unit device may still be operating correctly, and it’s the pads that are impeding you from experiencing the same level of relief you once had while using the unit.
