I have been trying to dilute 1tsp of citric acid crystals in 20ml of PG for about an hour now and they won't completely dissolve...
The mixture is in a glass bottle sitting on a coffee cup/mug electric heater and it gets very hot, almost too hot to touch the bottle.
What will help this process work?
