The process will remove the paint and the rust, given enough time to work. It loosens the bond the paint has, and then it peels up in strips. I think you’re further ahead if you hit the paint with a wire brush first though, it will speed things up.

It won’t do the rubber a bit of good, but it’s hard to say for sure whether or not it will be harmed. The process takes paint off metal fairly well. If the trike’s tires are like the ones on pedal cars, they can be removed by cutting them off. There are replacements available for pedal cars; I wouldn’t be surprised if there were for tricycle tires as well. Good luck!

A table spoon per …
A table spoon per gallon of water. You may use the solution perpetually for multiple parts but eventually it will depleate the water through evaporation, the washing/baking soda will not deplete. Therefore you should add more water to maitain the aforemention ratio, but do not add more W/B-soda as it will not benifit your rust removal operation.
After a few parts however, you will probably want to dispose of the solution because of crud.
Next time use Google its ur friend~!

Thank a ton for …
Thank a ton for this tip, I know most who will use electrolytic rust removal will thank you, under their breath, in unison.
Further note: make sure that if you use salt for increased conductivity, to get the polarities of the part and electrode right the first time or risk having your part desolve, quite literally, before your eyes.

The difference …
The difference between muriatic acid and electrolytic rust removal is that the former removes the rust compleately and seperates it from the “Good” metal. The latter of the two actaully restores the rust closes to the host metal back to actual metal state. Less pitting and deterioration of the patient part is the result.
It should also be noted that after a piece of metal goes trough the electrolytic rust removal it should be stabilized with paint or oil imediately after.
