Methods for Rust Removal from Antique Tools without Destroying the Patina?

Q. What is the best method for moderate to heavy rust removal that won't damage an aged patina? I've had great success removing rust with chemical products such as Evapo-Rust.
but what is left afterwards is a dull gray surface that lacks the character of the original. Restoring a decent surface requires abrasives, but this isn't always possible when say there are just spots of metal surrounded by a japanned finish.

The reason I ask is that old tools are valued by both users and collectors for their historical significance, quality of manufacture, and the patina that develops over years of age and use. Newly discovered tools (from garage sales, estate sales, grandpa's tool chest, etc.) invariably have rust obscuring a beautiful antique beneath. While heavily rusted tools often only benefit from a full restoration, tools in good shape can be cleaned with a light touch using mineral spirits [on eBay or Amazon] and 0000 #0000 steel wool [on eBay or Amazon].

The problem for many old tools is that they are rusted enough to leave them borderline collector and/or user quality. These tools are most appropriate for actual use, but being craftsman themselves, user's still value the look and feel of an well maintained tool with a rich patina, but can't necessarily justify or afford to buy a collectible in good shape for shop use.

A. Try 5% ammonium citrate,pH must be 3,5(50 gm citric acid [on eBay or Amazon] /1 lit water + add some ammonia). This solution can be thickened with corn starch or wallpaper glue(cellulose based). When object is clean neutralize with 5% baking soda [on eBay or Amazon] and then rinse it well. Hope it helps and good luck!

A. I have been looking for a way to clean rust off of old stoves as well as old tools. They were my fathers and he passed away. Now I have 100's of very old tools, wood working tools, welding tools, potbelly stoves, about 50 kerosene lanterns. What would be best.
