SLR stands for Shimano Linear Response and is a later brake lever than the N600EX ones.
For cleaning and polishing old alloy parts by hand, I've found Mother's Paste Polish (sold in automotive sections of stores) to be absolutely amazing stuff. I put some on a hub t hat was brown and it cleaned that hub and polished it up (with a micro-fibre cloth) just like new.
