Hello, I am about to begin the daunting task of blade cleaning. I use a wire wheel on a bench grinder on the blades once @ beginning of season & then they are maintained w/ a wire brush prior to sharpening & balancing. Allot of the caked on grass is too time consuming to remove throughout the season. I was considering dumping the blades in a vat w/some kind of solvent, perhaps paint thinner, for a few days & then pressure washing them instead of using the bench grinder w/wire brush. Has anyone done this & if so can you recommend a solvent that would be suitable for removing organic matter from steel.
