Given half a chance I'll be off to Northampton market to get some various 50/50s and a new load of clearos.
This certainly doesn't love 100%VG and the pair of us are struggling with each other.
Live and learn, eh.
As previously mentioned, VG is thick. Some people water it down at the mixing stage with either distilled water (some use tap water, or tap water boiled), or vodka if they want a good throat hit. How about trying adding a small amount of water to your clearo and try it? Worst case you've wasted a little juice, best case you cure it.
