Well I finally did it, I pulled the 1973 Kawasaki 125cc out of my mother in laws shed where it has been for the last 20 - 25 years. It is a mess but I figured I will start with the obvious and go from there. The gas tank is coated in rust on the inside and I am looking for feed back from you guys about the pros and cons of the diffrent methods. I have seen several ways of doing this including Freebirds post on Kleen. I figure either way I go I will be putting washers, chains or some other metal in there with a good spin to loosen up all the surface rust and break loose all I can before going with the chemical cleaners. Someone suggested tieing the tank in a blanket with washers in it and putting it in the dryer on NO heat for some time to get it all knocked loose.
What are your thoughs on the following methods:
1. Navel Jelly
2. Kleen
3. Electrolosis
If you have another idea I am all ears. I want to know which method you think is best and more importantly in my case idiot proof.
