Mouse cursor moves by itself on Windows 7 with PS/2 and USB mice, MBAM clean

On some pads, laser mice behave interestingly. I used to struggle with the washer because there was a nice white line on it that spoiled my chic.
Laser mice do actually wander around the screen from time to time, and this is normal. You don't touch her and she wanders off to one corner. Even without a pad on a uniform color surface, sometimes it is not a virus.

4Tech has good mice. My father used to have one of their mice in his laptop, and it was amazing. I used to have a 5-button mouse (4TECH) for the PS2 connector, it had a ball inside, it had to be cleaned once a month, but it still works (it's lying somewhere in a drawer). On the other hand, optical mice should generally be washed from the outside with, for example, foam. The same applies to the keyboard because it accumulates the most germs. After 5 years, the uncleaned equipment must look nice ... once I saw a mouse in a heavy smoker, not cleaned from the news. I couldn't stand it and asked for a cloth and soap because I was disgusted by the equipment. Rach snip and the keyboard and mouse like new, the client was shocked ... The best thing is that even yellowed plastic can be repaired with perhydrol + sun, but that's another story.
The mouse has spacers on the underside (rubber or plastic) that are in contact with the ground, they must be cleaned as the mouse behaves strangely. The second important thing is the transparent prism (I'm not sure if it can be called a prism) through which the ray from the diode passes and the reflected beam returns. There must be no dust or fur there. Once I had a cat hair on this part, and I couldn't understand why the mouse wasn't working.

On the other hand, a cheap optical mouse may behave strangely after a few years. Mostly, however, the problem concerns the buttons or the cable (laptop mouse) in my mouse, I have already changed the cable 2 times, I have replaced the buttons, but I will probably say goodbye to her in a while.

I do not have isopropyl alcohol.

Isopropanol is used, for example, for cleaning optical fibers and, in general, for many elements that require oxide removal from the surface. It is the only alcohol that should not tarnish the plastic. However, any solvents, nail polish remover, after-shave lotions based on ethanol, denatured alcohol (in any form) etc. must not be used especially for transparent materials, LCD monitors, etc. God forbid!

I would not use isopropanol to clean the LCD (just in case), but apparently you can.

It is best to use a computer cleaning foam or a little good liquid soap and water to clean the mouse. Of course, we do not soak the electronics. If you do not decide to open the mouse, clean it from the outside with a cloth dampened with soap and water, and then thoroughly dry the surface. If you plan to open the mouse (I recommend), take out all the elements and wash them thoroughly, then wipe and dry.
Do not use rough cloths for washing dishes as they may scratch the surface. I do not know what else to write because it is such a simple operation that it is difficult to spoil it.
