Use a mild detergent, then rinse with tap water and distilled water

To sterilize a plastic dispenser tap, one method is to use a mild detergent, then rinse with tap water and distilled water. Firstly, it is important to note that not all plastics can withstand sterilization, so it is recommended to review the technical specifications and consult with manufacturers to verify the suitability of a given method.

To begin the cleaning process, fill the reservoir with a mild detergent and water. Ensure that the detergent is suitable for plastic and avoid using abrasive cleaners or scouring pads, as these can damage the surface. Rinse the dispenser with tap water to remove any soap residue. Next, refill the reservoir with distilled water and drain it through the tap to ensure that any chemical residues from the tap water are removed. Repeat this process 2 to 3 times to ensure thorough rinsing.

Additionally, you can also use anti-bacterial dish soap and hot water to wash the dispenser. This method will kill surface bacteria, but it may not guarantee complete sterilization. For the best results, follow up with an alcohol rinse. You can also soak the dispenser in a bleach-water solution of about 5 to 10 percent bleach, as bleach will quickly disinfect the surface.

It is important to note that these methods focus on sterilizing the dispenser and taps. If you also need to clean the exterior and surrounding area, you can use disinfecting wipes or a washcloth with warm water and dish soap.

Wash with antibacterial soap and hot water

To sterilize a plastic dispenser tap, one method is to wash it with antibacterial soap and hot water. This is a simple and effective way to prevent the spread of germs and bacteria.

Firstly, it is important to prepare the dispenser tap for cleaning. If your water dispenser has a hot water tap, turn off the heater by flipping the switch on the back of the machine and unplugging it. Remove the water bottle, and then lift out the no-spill guard and baffle inside the reservoir.

Now, the plastic dispenser tap is ready for washing. Wet a washcloth with hot water and add a small amount of antibacterial soap. The soap will kill surface bacteria, but it may not guarantee complete sterilization. Wash the tap thoroughly, ensuring that you cover all surfaces. You can also use a small brush or sponge to help scrub away any remaining dirt or grease.

After washing, rinse the tap with hot water to remove any soap residue. Repeat this rinsing process with fresh water two to three times to ensure that all traces of soap are removed.

Finally, dry the tap with a clean cloth or allow it to air dry before reassembling the dispenser. It is important to ensure that all parts are completely dry before reuse.

While this method is effective, it is worth noting that there is limited evidence to suggest that antibacterial soaps are significantly more effective than regular soap and water in preventing illness. Regular soap tends to be less expensive and can be just as effective when used properly. Therefore, this method can be adapted to use regular soap if preferred.

Soak in a bleach-water solution

To sterilize a plastic dispenser tap, one method is to soak its components in a bleach-water solution. Firstly, unplug the cooler from the wall and remove the bottle. Then, remove the no-spill guard and baffle inside the reservoir. Check the manual for specific instructions on how to do this. Next, mix a bleach-water solution. The exact ratio of bleach to water will depend on the specific germs you are targeting. For example, a 1500 ppm solution is suitable for general disinfection, whereas a 2000 ppm solution is required to kill additional germs such as Strep and Listeria. Alternatively, a common recommendation is to add one tablespoon of bleach to a gallon of water.

Once you have prepared your bleach-water solution, fill the inner reservoir of the cooler with this mixture. Allow the solution to stand for 2-5 minutes. Then, rinse the reservoir with water 4 times to flush out the cleaning mixture. If you have a bottom-loading dispenser, set the water pump directly in a bucket of the cleaning solution and drain about half of it into another bucket using the tap. Leave the remaining solution in the cooler for 10 minutes to disinfect. Finally, drain the solution and rinse the reservoir with water 2 to 3 times to remove any traces of bleach.

Heat in a dishwasher or microwave

To sterilise a plastic dispenser tap, you can use a dishwasher or a microwave. However, it is important to note that plastic containers cannot handle the same heat as glass or metal containers and can melt. Polypropylene plastics are stronger than standard plastics and can withstand high heat.

If you choose to use a dishwasher, place the plastic on the top rack and ensure that it is not heavily soiled with food. While this method will clean the plastic, it may not sterilise it. To ensure sterilisation, you can combine this method with another, such as using an antibacterial dish soap.

For the microwave method, first, wet the plastic dispenser tap. This is important because the interaction between the microwave's heat and water causes sterilisation. Place the tap in the microwave on high power for approximately two minutes.

It is recommended to combine these heat methods with another sterilisation process, such as using a mild detergent or anti-bacterial dish soap, to ensure complete sterilisation.

Use a UV lamp

Using a UV lamp is a safe, non-heated method to sterilize plastic. This method is widely used in food processing, laboratories, and water treatment. It is important to note that UV light will only travel in a straight line, so any shadow or obstruction will reduce its effectiveness. Therefore, it is crucial to ensure that the plastic dispenser tap is transparent or clear to allow the UV light to penetrate and sterilize the object effectively.

To use a UV lamp for sterilization, you can follow these general steps:

  • Obtain a UV lamp: UV lamps are commercially available, and you can purchase one that suits your specific needs.
  • Prepare the plastic dispenser tap: Ensure that the plastic surface is clean and free of any debris or particles that may obstruct the UV light.
  • Position the UV lamp: Place the UV lamp at an appropriate distance and angle to ensure maximum exposure to the plastic dispenser tap.
  • Expose to UV light: Turn on the UV lamp and allow the plastic dispenser tap to be exposed to the UV light for a sufficient amount of time. The exposure time may vary depending on the intensity of the UV lamp and the level of sterilization required.

It is important to note that UV light has a sterilizing effect on the exterior of objects, and its effectiveness in penetrating the interior of an object depends on the material and design. In the case of plastic dispenser taps, the UV light should be able to reach all surfaces to ensure effective sterilization.

Additionally, while UV light is an effective sterilizing agent, it is important to be cautious as UV exposure can cause some plastics to break down, become brittle, or change colour. Therefore, it is recommended to test the UV lamp on a small area of the plastic dispenser tap before proceeding with full sterilization.
