I do my final polishing with Mothers Mag & Aluminium polish.
Decided to try using a paper towel instead of a generic red cotton shop cloth.
This was based on something my optometrist told me: never clean your glasses with a kleenex or a paper towel - they are made out of wood fibers. Use a soft cloth - made from cotton fibers.
To me, the paper towel produced a higher shine in a shorter period of time.
