Process for cleaning Keyboards and Plastic:

Each keyboard was processed individually in the Mi40 wash tank using our Galvex 18:01 with a concentration of 3% for 5 minutes. After the cycle has completed the keyboard was immediately removed and placed in the rinse tank for a further 5 minutes. This is to ensure any dirt or cleaning fluid left on the keyboard is removed and will not dry on or stain the keyboard. After the rinse cycle, the keyboard was placed into the Mi dryer unit for 20 minutes at 45°C.

Will ultrasonic cleaning damage plastic?

One question that frequently arises when it comes to ultrasonic cleaning is whether it can damage plastic. After all, plastic is a highly versatile material that is used in a wide range of applications, from household items to industrial products. The effect of ultrasonic cleaning on plastic depends on a number of factors, including the type of plastic, the temperature of the cleaning solution, and the duration of the cleaning process. Some plastics are more resistant to ultrasonic cleaning than others, and some may be damaged if exposed to ultrasonic waves for too long. Polyethylene, for example, is a plastic that is highly resistant to ultrasonic cleaning. This is because it is a low-density polymer with a relatively low melting point. Other plastics, such as polycarbonate, may be more susceptible to damage from ultrasonic waves. Polycarbonate is a thermoplastic material that has a high melting point, which means that it can be damaged if exposed to high temperatures for too long.

In general, the longer an object is exposed to ultrasonic waves, the greater the risk of damage to the plastic. This is because the energy created by the bubbles can cause the plastic to heat up, which can lead to warping, cracking, or other forms of damage.

Will ultrasonic cleaning remove grease?

Ultrasonic cleaning is highly effective in removing grease from different surfaces. The energy generated by the collapsing bubbles of an ultrasonic cleaner is capable of penetrating into the tiniest crevices of a surface, dislodging and removing grease that has accumulated in these hard-to-reach areas. Additionally, ultrasonic cleaning can remove grease that has dried and hardened on surfaces, making it a useful method for cleaning machinery and equipment. While ultrasonic cleaning is generally effective in removing grease, there are several factors that can affect its ability to do so. These factors include the type of grease, the cleaning solution, the temperature, the duration of the cleaning process, and the frequency of the ultrasonic cleaner.
