I think my lamp got bumped around in the car, because there are floating particles in the liquid. It's not so cloudy I can't see inside it, but there are definitely particles inside, and the wax has a weird texture that suggests it would feel rough and grainy if it were out of the liquid. The liquid kind of looks like it has a light mist and dust.
Does anyone know a way to clear up the lamp? I've only found advice for lamps that are completely clouded over to the point where you can't see anything inside, so I don't know if the same ideas will work in this case or which one to use.
