My musical saw has, despite my best efforts, got little patches of rust on it. How Do I go about removing the rust without spending too much on rust-removal products and without affecting the properties of the steel?
Steel wool and a bit of WD 40. Steel wool will remove the rust and the WD 40 will protect it in the future.
I would suggest rust removal by electrolysis. Search youtube for that. It probably will not affect the metal but there are no guarantees. I would run a test on another metal. Also this process can be dangerous because hydrogen gas is a by-product - remember not to smoke or be cooking nearby! The Easy way is with BlackStar Rust Remover. It will turn the metal black and convert the rust to metal which can then be painted or left black.
