Hi folks, I have just picked up an Underwood model 6 11 (?) and I am in need a some assistance on a few things.
Here she be in all her glory:

I would like to clean it up and hopefully get it functional again. I think there is good potential with it, but I'm way out of my wheelhouse with this project. Also, I am not typewriter-literate, so please bear with me on terminology!
Some of the issues I'm up against are:
--Broken carriage return line (looks like a piece of string vs. a band).
--Cleaning it without damaging the decals or the legends on the keys.
So, questions...
--Is there a preferred solution for cleaning the dirt and old waxy buildup on the mechanisms?
--Is there an easy way to remove the carriage and/or platen to permit better access to the bits and pieces for cleaning?
--Is there a recommended replacement for the carriage return string?
I appreciate any insight or links to existing threads that address my questions.
Thanks for looking!
