2 Rinse and Shake method

First method is perhaps the most laziest and unsafe methods. It involves putting your hands under some water and shaking it dry instead of washing it thoroughly. It usually happens when you are short of time and in urgency. But when Jennie rinsed her hands under water for 3 seconds and shook them, the UV light showed that her hand glowed like Christmas lights due to presence of bacteria despite shaking the water away from the hands. Only little bacteria around the fingers were washed away and rest of the hand was still dirty. Even experts have termed that just a quick rinse and shake is not the best method to wash hands.

3 Six Second wash without using soap

According to research, six seconds is the longest anyone washes their hands after using the toilet either at the home or in public. Jennie’s hand still looked covered with bacteria despite washing her hands for six seconds. Remember no soap was used, just water and under the UV light, her hand still shows bacteria covering the back of her palm and fingers. Correct method to wash hands is to rub the palms together and interlace the fingers to scrub them nicely to ensure the hand is cleaned nicely. Jennie also dried her hands using a towel, which lessened the amount of bacteria on her hands, an important thing to do.

4 Six second wash using a soap

Jennie this time uses soap, which actually should be used when washing hands and preferably a soap containing some anti-septic and antibacterial solution in it. Soap is sticky and the bacteria are washed along with the soap and when rinsed with water, the dirt also gets removed from the hand along with the soap and bacteria. Lather formed during the washing process also causes ease in rubbing the hands and washing them properly. Jennie’s hands under UV light are relatively clean, but nails and cuticles are areas which are problem areas with bacteria present in large quantities in it.

If you have worked on something really dirty and filthy and used your hands to do it, then you should prefer washing your hands for over 15 seconds and maybe even 30 seconds.

7 What is better a dryer or using a towel?

Now this is a debate that has been going on for a long time – what is better to use, a dryer or a towel. Unfortunately the research on both of these methods to clean your hands remains inconclusive. Advantage of using a towel is that rubbing your hands to dry them will remove any bacteria or germs that you missed during the washing of the hands. Using an air dryer requires patience, since it takes time to dry the hands completely. But please avoid using towels that have been used by many people and is wet, as it can contaminate your clean hands with bacteria from other people. Better carry a small hand towel with yourself and use it wipe your hands and clean that towel nicely.
