Only time I use WD40 is after taking out of the water bath- actually does a good job of displacing the water.
Yep, I use WD-40 for that as well. That is after all what it was designed for (WD stands for Water Displacing, but I'm sure you knew that
I use Sodium Nitrate rather than Ammonium Nitrate, it is easier to get. Although many people do not know the difference and they give you funny looks when you ask for it at the hardware store
I wrote about my learning process on my blog (if you are interested....)
