"Removing rust from inside a bicycle frame"
I need to clean some light rust from the inside of a bicycle frame. I was told that this could be done with a low percentage muriatic acid and water solution and then rinsing. Where can I find details on how to perform this job and what is a low percentage solution (1 part acid to 3 parts water?)Rob Schlumpberger

There are hot alkaline rust removers that work well, but cost too much to set up for a quantity of one. Muriatic acid will take out the rust, but it will rust worse after the treatment, even with excessive rinsing. Try to find a non toxic rust remover. Normally this will be a Citric Acid [affil link] formulation. Mega safer, but use proper protective equipment; gogglesGoggles [affil link] , rubber glovesProtective Gloves [affil link] and apron [affil link] are an absolute minimumJames Watts

I have a question in regard to the last comment: will the non toxic rust remover keep the rust away for good if applied properly?Zach M

Certainly not, Zach.
The reason automobiles have such extensive treatments -- all turned edges, no exposed welds; galvanneal material; phosphatization; multilayer paint; clear coat -- is that all of those steps are mandatory to provide long term rust prevention in exterior use.
