Clean all dirt and soil from the garden tools. As tools age the steel gets pitted. Scrub out all traces of dirt before sanitizing.
Find a bucket large enough to completely encompass the tools' steel parts -- shovel blades, fork tongs and pruning shear blades.
Mix a solution of 80 percent warm water and 20 percent household detergent; lysol works well, does not corrode tools and is relatively safe to handle.
Dip each garden tool into the solution, making sure all parts of the blades come into contact with the liquid.
Set the tools on a clean, dry surface to air dry. Put tools away when dry or use them in the garden.
