Rust spots will turn to pits anyway as the rust eats away the bare metal.

Hello Jean,
If pineapple juice does not work because the rust is too thick ,I move on to electrolytic derusting using:
- any battery charger in the 4 amp to 20 amp range will work. (The lower the current, the longer it will take to get the job done)
Connect the Negative lead to the part that you want derusted!!!
-for the solution: About a tablespoon of household / washing soda to a gallon of water. (Fine bubbles will rise from the object when cleaning is in progress)
-after some hours scrub with Scotch Brite , rust scale is loosened and can be easily removed. Un-rusted metal is not affected in any way.
