Shimano 600 friction shifters

My vintage Cilo roadster has the 600 group, and the right (downtube, friction) shifter is getting increasingly hard to tighten enough to prevent slipping in the lower gears.

I was considering swabbing down the innards with a solvent like acetone to remove any oily buildup...Anything else I can use to improve things?
I don't suppose new friction bits are still available.

I forget what the internals look like on those but seems to me they were pretty simple to take apart and re-grease. Best to stay away from acetone if there is anything that's not metal or painted. Wd-40, Kerosene, Simple Green, Orange cleaner etc. work good for degreasing. Not sure if these are the same as what you have but new shifters are available here and cheap. http://www.loosescrews.com/index.cgi...d=291613429221

Take it apart and clean it,it's not getting full contact.I don't put grease on mine,makes it to slippery and attracts dirt.Mine are 32 years old,get ridden everyday and work fine.

If you need a new friction pad,try Loose Screws on the web,they might have one.
