Hey Cabers. I bought this bike from The Golden Greek and received it a couple of weeks ago. It's all original and we thought it was green. Prior to shipping, George removed the old tires and saw light blue paint on the rims and wondered if it had been originally blue. If you look closely at the before picture you will see a small patch of blue paint that looks like a piece of tape or something covered this small spot. Upon further investigation I believe the original owner may have sprayed it with an oil preservative which overtime turned the blue to sage green. George suggested that I give it an Oxalic acid bath, so I completely disassembled the bike, mixed up the solution and submersed it overnight. I rinsed it down and after it dried buffed it was some wax. While the bike was soaking in the acid I completely rebuilt all the mechanicals. I still need to recover the seat, but besides that she's a beautiful blue. I'm going to give it to my youngest granddaughter Katie

Unreal transformation!

Question. Did you or does anyone else wipe down the parts with a degreaser before soaking them in oxalic?

Cabers,
Thanks for all the kind words and compliments. The Golden Greek made me a believer in the Oxalic acid bath. The before and after pictures are real. If you find an old bike with the original paint, but covered by decades of dirt and grime that doesn't wash off, try the Oxalic acid bath.
By the way - after my bike soaked for a few hours, the water started to have a light ordor like sulfur gas or rotten eggs. I told my wife "That Stinks Good"!!! JimRoy.
