Wes how long have you been scraping? 5 years? I have been scraping for 50 + years. I do not dilute the ink with Windex, I dilute the Yellow highlighter or "red lead substitute" with Windex. I also clean the granite surface plates with Windex. It evaporates fast after it is wiped off. I used to sell Tru-Stone / Starrett surface plates and they sell a plate cleaner that in basically red Windex.
If you took my class I have offered for free to you, you would know. I also tell students NOT to use Windex on Canode bluing unless you working in a 100 degree HOT shop. I also teach if you blue something up, to scrape it off and to clean it off plates, straight-edges and parts that the inks are on before leaving the shop for the day, oil the cast iron.
I assumed Lucky was covering the Straight-edge so lint in the air didn't pollute the inks. Lucky has been scraping as long as you have been, maybe more. I would trust his writing more then yours any day of the week. I have been thinking of commenting on your You Tube on the comments, but haven't yet.
