Zeiss Ikon Super Ikonta 531 lens cleaning

1936 Zeiss Ikon Super Ikonta 531 medium format folding camera (6x4.5) with a hazy lens (Carl Zeiss Jena Tessar 7cm f/3.5). Important Disclaimer: I am not a professional, so please be careful if you follow this video and attempt to do the same, and consider advice from other sources as well. I did a lot of research before doing this repair, but my experience is not a substitute for doing one’s own leg work.
