How to clean lens elements in Canon FD 50mm 1:1.8 (new version)

In this video I will show how I try to clean the lens element’s in my old Canon FD 50mm 1:1.8 (new version), I use lighter fluid to cleaning the lens surface and it look’s really good. There was also a very small area with fungus on the 3. lens group, so I try to clean it some Hydrogen Peroxid 3%, and it work’s perfect. But when I assemble the back lens group’s I made a mistake because I put the 3. lens group in the wroooong way, well, I figure it out, and everything was correct again without any damage.
