Regular dishsoap (like Dawn, for example) works great for rinsing too, so you don't really need to go out and buy a bottle of Jet Dry just for this, though it can be nice to have one on hand.
I had seen, I believe it was TVCasualty using hydrated lime to hydrate WBS as well
I don't add lime to a substrate, but I do add chalk since it helps buffer pH. Chalk is hard to come by where I am, at least it's hard to find cheap chalk, but I got more than I can use in several years by taking a 25 pound bag of hydrated lime, opening it, and letting it sit for a year (I should add that it wasn't wide
open; I'd used some then rolled the top of the bag down and put it in the shed outside). I forgot about that particular bag, and later read about lime 'degrading' into calcium carbonate over time if exposed to air/humidity. it works, since half a cup
of year-old lime did not appreciably change the pH of a single liter of water! Normally, one tablespoon would make the pH skyrocket. I add it at a ratio of about half a cup of old lime per 12 jars, give or take. When trying this, be sure to add a little more water to compensate. Casing layers love the chalk buffer as well...
A gram of gypsum per quart jar is good too, and helps make the grain much easier to break up when shaking.
