I have many empty plug-in type scent holders that I'd like fill with FO. I've tried just pouring some in but it didn't work. I think it might be clogging the "wick". It looks like I need to dilute the FO but with what? OO maybe? Distilled water? If I use water, I'll need an emulsifier, right? Will PS 80 work? Hopefully someone has tried this and can direct me before I waste a bunch of FO!
