AirStill - Can I distill twice for the same Alcohol percentage?

[dustytrash]

I have an AirStill. Following the instructions I've distilled 4L @ 18% to get a 720ML product @ 60%.

I've done this 4 times, each time discarding the fore-shot & the tails. However on my last run my distiller puked a little and I now have some cloudiness in my finished product. I also see a little tiny piece of debris. I'd like to distill again for a clear & clean product, but I don't want a higher percentage. I want lower, or equal.

The instructions say I can distill again for a product of 90% (Which leads me to believe it's safe to distill a 60% product), so am I safe to distill again and collect everything? Can I add some water, distill again to get a lower percentage?
