Bought some of this today to try on my Festool TS55 blade. I sprayed it on a section of the blade and waited a few minutes and then used an old toothbrush to scrub it down as well as a cloth to wipe things down. It would probably even work better if you could submerge the blade right in the solution for several minutes and then scrub and wipe off. I only cleaned the bottom left quarter of the blade for these pictures. There were a couple spots where I couldn't get all the grime off, but they were pretty small. Overall, it worked better than I expected.
