I tend to have a lot of ear wax build up and use Otex to help, and it does. I have it at the side of the bed. I woke up 2/3 weeks ago now with my ear irritating, being half asleep and not switching the light on, picked up the bottle and put 3/4 drops in while still laying on the one side. I've used a vape pen now for four years instead of tobacco, guess what I had also left on my bedside table, same size bottle, YEP, I put 3/4 drops of vape liquid in my lug hole. never moved so fast to the bathroom to try and wash it out.
