The acrylic plate is often used in our homemade keyboard kit, but we recommend that you refrain from using alcohol disinfection and use a neutral detergent if necessary.
If alcohol comes into contact with acrylic, cracks called chemical cracks may occur or the acrylic may turn white and cloudy.
I tried it with an acrylic plate that I do not plan to use.
Here is the original response. beautiful.
I sprayed it with alcohol a few times and let it sit for about 15 minutes.
You can see that cracks are generated from the four corners of the switch hole.
When I applied some force (although it felt a little too tight), the fragile part broke easily.
I think that there are times when disinfection is done at events, etc., but I think it would be better if you put it in a corner of your mind and act.
