The tubing made from silicone is well-performed in UV and heat resistance. Silicone tubing is also very easy to clean and sterilize, thus it is widely popular in the food industry and medical industries. How to clean and sterilize silicone tubing?
If you are using silicone tubing in a food product processing environment—in food process facilities, it is very vital to clean the silicone tubing regularly. Silicone tubing is very available for homemade equipment because you can boil it to clean the goo that had existed inside the hose. It should be cleaned regularly to prevent blockages and foul odor.
If you are using silicone tubing in the automotive industry, cleaning is a regular step.
The easiest way to clean the silicone tubing is: to use hot soapy water to clean the inside of the tubing. As for the temperature of soap water, there is no strict requirement for silicone tubing to be heat-resistant. We should keep in mind that we should avoid using WD40 and petroleum-based cleaning products. Some cleaning products may react with silicone further damaging its structure and functions.
How to sterilize the silicone tubing? There are several ways:
(1) Gamma irradiation. But this sterilizing method can change the structure of silicone as well as silicone become easier to knot
(2) Electron beam irradiation;
(3) Ethylene oxide is another effective sterilization method for most organosilicon materials. But this method has a drawback that is silicone will absorb ethylene oxide, so you need to remove the substance before using silicone tubing.
