Since my tank is particularly rusty i've been looking at methods to "de rust" it. I came across this thread https://www.mopedarmy.com/wiki/Removing_rust_from_a_gas_tank that had several methods for tank "cleaning" and found it very interesting. Let me start by saying i've not tried any of these methods and can't vouch for any of them. I've seen most all of these methods listed in various places before except the electrolysis method. Has anyone on the forum (or anyone you know) ever tried this method before? I like the sounds of it for two reasons; 1) it seems like it produces less toxic mess you have to dispose of, in fact they state you can pour it on your grass (hmm, i wonder) and 2) it doesn't eat metal away like all the other methods. What are your thoughts on the electrolysis method?
