Cleaning Keyboards with Ultrasonics

Yesterday I was looking at my computer keyboard and realized that it was time to clean it. Like everyone else, I too sometimes eat at my desk, drop crumbs in the keyboard and have general dirt build up over time. Unlike everyone else, I have unlimited access to ultrasonic machines to clean my keyboard.

Before starting, I decided to take some photos so everyone could see this quick and easy process. I also took some readings both before and after the cleaning so that everyone could appreciate the cleanliness difference that ultrasonic cleaning really makes.

First, the Swab Test

We took a pre-swab for an ATP (Adenosine Triphosphate) test that measures bioluminesence or signs of bacterial life. This count gives a starting point and is a great way to verify that our cleaning is working. As you can see, the count on my keyboard was 181 (dirty!).

Most people don’t appreciate that their keyboards can be a breeding ground for germs. In fact, there has recently been much discovered and reported about in the news on how keyboards at nursing stations have been one of the main causes of the spread of MRSA in the hospitals both domestic and abroad.

Next, the Cleaning

Next, we submerged the keyboard for one minute in our M-115(Mighty One) ultrasonic cleaning system which is regularly used for cleaning electronics of all types.

Results

After removing the keyboard and drying it with both our Heated Blow Dry Gun and in our Drye Rite electronics drying station, we performed another ATP swab test. This time the result was only 29 which is great (for comparison, in the food industry, anything under 30 is considered to be excellent).

The result is that I am now typing this blog from a keyboard that looks better, functions better and is verified as clean. If you are currently working in or considering ultrasonic cleaning for offices, hospitals, schools and other public areas, I would recommend you consider ATP testing along with your ultrasonic process to show your clients the difference that ultrasonic cleaning makes.
