Query: 8mm head cleaner for 8mm video camcorder

It seemed to work fine on cleaning the heads on my camera although I did have to use it several times before the tape would play without any lines going through it. I was able to view my old 8mm video's from 20 some years ago on my video camera that I taped them on. So I was happy with this purchase.
