It depends on how big the part is, and the time frame in which it will be needed. Electrolysis seems to be a popular method. I've always used plain white vinegar in a can or pan with the small parts soaking for several weeks at least. Vinegar will remove rust, crud and paint when left to work -it won't do anything in just a few hours or days even. Small parts can be put in a plastic coffee can, covered in vinegar, then the lid replaced as the stuff will evaporate fast otherwise especially in hot weather. A larger container like a plastic dishpan will work for slightly large parts like tools, but be sure to also cover. For real big parts, a small kiddie swimming pool will work. Use a plastic container with vinegar so it doesn't have to compete with the metal like a tin coffee can, if you still have any. Vinegar is about $5 per gallon so consider costs on bigger parts. Electrolysis is the way to go on those. Finding a place that will sell lye can be a hassle too. I've used old mower blades for conductors in my tank. We have methods in or HOW-TO's forum to help you decide as well. here is the one for electrolysis...
