|Rust prevention and removal|
First up, in the spray bottle, CMT's Formula 2050 bit and blade cleaner. Yep, its made primarily for power tools and by a power tool company, but it's awesome for anything. If your tool has pitch, sap, gunk, whatever, this will remove it. It is also a good de-greaser. It's friendly to work with being non-toxic, biodegradable, and non-flammable. It also provides rust and corrosion protection. I have little to no rust problems with tools I use this on. I order it from Highland Woodworking in Atlanta and it's currently $9.99 for the 18oz bottle. If you are a home shop it should last you a while, can't remember the last time I bought some and I use it all the time. A spray or two will do ya!
Next up, Autosol. This is some great metal polish. Made in Germany for the automotive industry it polishes up any kind of metal. Will remove light rust, patina, etc. A white paste, it works partially chemically and partially abrasively. Leaves a silky smooth surface. No idea where I got this but I see its available on Amazon, eBay and other places for a variety of prices. I have the 75ml/3.33oz tube and it will probably last me for the rest of life. Definitely worth having around.
Last but not least, the sandflex block from Klingspor. Also made in Germany, its a rubber block like an eraser impregnated throughout with metal filings. This is the big gun for eliminating rust. You'll have shiny metal in no time. It's also good for removing that clear lacquer they put on everything now to prevent rust. Available from Lie-Nielsen for $7.00. Comes in coarse, medium and fine. I have the medium and it does the job.
There you go, three things to keep your tools happy and rust free, whether they are powered by you or electrons. Enjoy.
