Here's how I remove rust from small parts, IE nuts, bolts, small brackets, widgets, ect.
It works surprisingly well.
1. Remove any and all oil, grease, ect from the item.
2. Mix up a solution of 50% white vinegar and 50% lemon juice.
3. Submerge the item to be de-rusted in the solution for at least 24 hours. You can go longer if necessary, but I have yet to find the need to do so.
If you cannot retrieve the part from the solution for a few days due to life getting in the way, it will do no harm. The solution seems to be quite gentle to the base metal as well as chrome or zinc plating.
4. Wash the item in warm soapy (I use dish soap) water to remove the black film that will form on the surface. It basically wipes off easily. I have never needed to scrub vigorously.
5. Immediately dry the item and oil it to prevent flash rust from forming.
If you plan on painting the item, do NOT oil it! I have found that dunking the item in a treatment such as Metal Treat (sold in the automotive paint section as a surface preparer) works absolutely awesome. Follow the instructions on the metal treatment label for proper application. Metal treat will convert flash rust as well as the exposed cleaned outer surface of the steel or iron item into iron phosphate which prevents further flash rust and gives the surface a really good tooth for the paint or primer to adhere to.
nice tip!....and cheap .......never know what ya gonna pick up here.....
