It's always worked fine for me. I use a mix of 1 part white glue to 3 parts water, and I use straight 90% isopropyl alcohol dripped on from a pipette as a wetting agent.
By the way, I'm also a heavy-handed caulker, so there's lots of the stuff under my track, too.
One thing you might consider is painting the caulk with a dark color if you've really got a lot of it. That way, any small missed spots won't show up as readily. Or, you can wait until the ballast is dry and then touch those spots up with cheap acrylic about the same color as the ballast.
It takes an iron man to play with a toy iron horse.
In one of his videos, Joe Fugate recommends using grey latex caulk because it matches the ballast color in most cases. That should eliminate having to paint the caulk.

Exactly right ... white glue and ballast bond very well to LATEX caulk, but not so well to silicone caulk. If you've used latex caulk, you should have no problem with your ballast staying put.
