Blast ye proprietary bottle and impulsive shopping. Here's how to get the oil out of a glade scented oil bottle into an oust scented oil bottle thinger... I proclaim, I like the oust bottles better - much easier to refill yourself without breaking the bottle.
Step 1: Poke It
Use a tooth pick of skewer, and press it into the glade diffusion tip.
Step 2: Push It
Using the skewer - push the diffusion wick into the bottle. It will likely break in half in the bottom of the bottle.
Step 3: Pull It
Pull the skewer out, and any remaining wick with it.
Step 4: Pour It
Pull the diffuser off the oust bottle, then pour the glade oil into the oust bottle.
Step 5: Stick It
Stick the oust diffuser back in, and then into whatever device it goes into.
