Thanks for your suggestions. I was indeed searching youtube videos, but couldn't figure out the name of the damned material. Is it vinyl, rubber or something else entirely, I don't know. Also, in some cases I found relative videos, but products used there aren't available here in Serbia, so I was kinda looking for some household solution so to speak.
Electric toothbrush sounds good, I will just have to wait a bit more, don't want to waste it just yet
