Last evening I spent some time working on my Genco Gold Seal SR. I did not want to remove the pin, so I did this by hand with only Mothers Mag and Aluminium polish on the blade, tang and tail. The rust on the tail and pivot I used a bit of sandpaper, and carefully used a home made sandpaper dental floss and regular dental floss to clean up the pivot. The after photo is not the best -- it shows the tail as being dark, but it is quite clean and shiny. There is some very small pitting on the tail from the rust. There is still some staining on the spine...but I am not going to be too aggressive with this razor at this point in time. It leaves a bit of the original character. For the scales I only used warm soapy water and Q-tips. I am quite pleased with the outcome.
