I smell a spell coming from previous versions of DnD that has been poorly ported, but here goes:
Glitterdust is a conjuration (creation) spell - it actually create real, physical dust which vanishes when the spell expires - but expressedly states that the dust can not be removed; so we can throw out all attempts to move it - no flooding, no washing, no blowing.
You don't want to get the Dispel Magic answer because it would be obvious, but it is the most straightforward and less bothersome way to do it after Dust of Darkness.
Interestingly enough, Glitterdust does not possess the [Light] tag as descriptor. So the next best solution is to obfuscate lines of sight. Darkness and Deeper Darkness could bring the light level to darkness or supernatural darkness in the spell area, giving you concealment. Effectively, since the line of sight is blocked, the outlining effect is moot. Same goes for Cloud of Smoke and the likes. You can achieve this effect via the spells or some magical items that replicate those effects.
Second best option is not to be invisible. And by that, I mean something like Blink, which makes you alternate between Material and Ethereal Plane. When on the Ethereal Plane, you're on an entirely different Plane, not just invisible, so Glitterdust outlining effect does not apply - though I'd argue the blinding part is still in effect if someone managed to pin it on you while on the Material plane.
I could go and enumerate a few options that are not what you're looking for, such as Stone Wall, which technically block lines of sight. But to sum it up, you can either hide the dust (by RAW) by varying the level of light or be one step above invisible.
Other than the direct spells intended to counter it, you're out of luck to counter it directly.
