>If you want to try phosphoric acid stick the chisel in Pepsi instead! ; ) In all seriousness, if the OJ (citric acid) worked, why not just use what you have? The phosphoric acid solution Bob S. speaks of is available in some hardware stores and is really just a more concentrated solution than the acid concentration of cola or orange juice. It will burn skin so a little more care needs to be taken when using it. However, if what you are doing works, go with it. If the rust is gone, then the OJ is doing what you wanted. Now if you want to blue you tools like Bob S. does that's something entirely different.

>You can get phosphoric acid at most auto parts stores. They are not sold as "phosphoric acid", but this is the chief ingredient. Naval Jelly is the name of the product I have on my shelf at the moment and is marketed as a rust dissolver. I don't like to use it on my wood working tools because it darkens metal.... primarily a cosmetic reason for me.

I prefer an abrasive. Sand paper for really bad stuff. For light rust, I use what are now called a "rust eraser"... rubber block loaded with an abrassive. Several wood working stores carry these, including LN. They are very effective.

>I've had good results using oxolic acid. It's avilable as "wood bleach", white crystals that you dissolve in water. Known a few marine mechanics who like to use it on marine outboards, and laundry people who use it to remove rust stains from clothing. Removes the rust good, but will leave on a chalky white/green residue that has to be buffed off or washed off. It's also naturally found in my two least-favorite foods: Spinach, and rhubarb(leaves)...
