Rust Free Shop Tools
Oxidation, or rust, is a natural process that occurs over time with the exposure of metals to moisture and oxygen. Since avoiding these two elements is not an option (at least with oxygen), taking care to avoid rust in shop tools will prolong their usefulness. Areas of the country with moist climates are particularly prone to the problem of rusty tools. Does this Spark an idea?

Rust Applications
-
Removing rust that has already found its way to your set of shop tools can be addressed in a few ways, depending upon the severity of the rust problem. For light rust, there are many chemical removers that are quick and relatively easy to apply, and may only cost $10 to $12. These usually require simply soaking the oxidized tools in the solvent, rinsing with water and drying with a cloth to remove excess moisture.
Sanding and Abrasion
-
Ridding oxidation from more stubborn rust problems may require sanding, or less-intrusive abrasive techniques. An old toothbrush or steel wool can be used to address difficult rust areas on shop tools, particularly in conjunction with a rust removing application. For significant rust issues, sanding the rust off using a rotating abrasive brush attached to a drill will work. Once the rust has been removed using either one of these methods, make certain to either re-paint with a rust-free paint or apply a sealant to prevent a recurrence.

Preventive Measures
-
Coating shop tools with sealant prior to rust taking hold will prevent the problem before it occurs. There are many rust "shields" or cloths available on the market to help in this area. Many rust sealants are in the $15 range. Also, keeping your shop tools clean and well-oiled will help to prevent rust build up and prolong the life of your shop tools.
Storage
-
Avoiding moisture, dirt and grime are key in keeping rust from becoming a problem. Often, it is the time between uses that tools are subjected to the worst oxidation conditions. Tools sitting in a metal tool box or drawer in damp or humid conditions will invariably become rusty. For smaller tool collections, adding a bag of charcoal (in a fabric bag to avoid dust getting on tools) or gel canisters that absorb excess moisture will go a long way toward maintaining rust-free tools. For more extensive tool sets requiring additional oxygen and moisture protection, you may want to consider a Vapor Corrosion Inhibitor (VCI), which regulates air and moisture for tools kept in larger areas (closets and other enclosures for example).
