I am interested in using oxalic acid to remove the rust from inside my frame. I have read that with some acids it is vital to soak it in water and baking soda after to neutralize it. Is this so with oxalic acid as well? How long should i leave my frame soaking in the acid bath? Should I dilute the "wood bleach" with water? And if so with what ratios? Thanks alot, I'm sure many other people will appreciate these details as well.
