8 Track Cassette Head Cleaner; CERTRON, 7182100-00

Once in a while it was suggested to clean your 8track player with a 'head cleaner'. Here is one from the 1970's by Certron, no. 7182100-00. You would insert the cassette and press play like a normal cassette yet there would be no music output. It's job was to 'clean' the playing system. Has been tested and relay-system works but no way of gauging if it cleaned my player. Perfect for nostalgic folk or those who need a deep cleaning of their old 8-track units!
