Re: How do you clean "Gum Wall" glop from rims?

I have a friend who has an old Schwinn Collegiate. He wants to ride it
again after leaving it hang in the garage for decades. The gum wall
tires have degraded and most of the residue has stuck itself to the
inside and outside walls of the rims. I tried cleaning it off with
mineral spirits and scraping it with a plastic scraper. After an
hour's work the front rim was clean enough to accept a new front tire.
What ideas do you have to save some time/work in getting the rear rim
nice and clean without damaging the chrome of the steel Schwinn rim?
Thank you in advance for any helpfu ideas.

Your description matches what I faced with a long-stored bike that was given to
me. It's also a Schwinn but with alum. rims. While the tire rubber was dry and
crumbly, for the most part, a significant amount of goo adhered to the rims. I
tried a little laquer thinner, rubbed on a small affected area with a flat piece
of pine. A new wooden paint stirrer would probably work as well and is easy to
acquire. Thinner didn't work as fast as I had thought it would, so after a
short time I decided to abandon it and use just the wood and water. The water
acted to keep displaced goo from re-adhering. There's probably a better, faster
method but what I describe here worked in the end. That was 2-3 years ago and I
don't remember how long the job took but I'd guess a couple hours per rim.
