My favourite corrosion inhibitor is now available in individually packaged wipes.
The oil contains a blend of ferrous and non-ferrous anti corrosion ingredients plus a vapour-phase corrosion inhibitor that will find its way into screw threads and seams. A little bit of VanGuard goes a long way, so you can protect a whole load of tools with each wipe.
When you are finished with it, don't throw it away. Both the empty packet and the used wipe will continue act as VCI emitters for months, so pop them in the bottom of your toolbox to give your tools continued protection from the dreaded red stuff.
