I just use the Tuf-Glide directly. One drop or more on each side of the blade, spread and wipe with a clean rag. This way I do not have to worry if my cloth is still effective as I can see a wet layer of Tuf-Glide on the blade. I also end up with my own home made "Tuf Rag", which I use for quick touch ups, eg. wiping off fingerprints after handling or after minor use.
I re-apply every 6 months or so for knives that I do not use. Has kept my carbon blades pristine and shiny. A patina does not even form.
But I really do not know if Tuf-Glide will last through a washing though.
