I'm in a small condo and work on my bike on our patio. I'm in the process of removing rust from the frame and decided on evapo-rust.

I believe the instructions for evapo-rust are to dunk your parts in a container of the stuff and let it soak for a few hours. Unfortunately due to my space constraints, I don't really have anything I can dunk a frame into, nor the space.

I was wondering if anyone had any techniques for this? I was thinking about soaking a rag in the stuff and wrapping it around the frame tubes where the rust is. Has anyone tried something like this with success?
