Removing post clean and brighten fuzzies?

We used the Gemini RAD Cleaner and Brightener to take a year's worth of gray weathering off our 'new' cedar deck.

Did a great job, but the cedar is quite 'knotty' and there is a good amount of gray fluff or fuzzies left over.

What's the best way to clean this material off? Not excited about another round of Cleaner/Brightener as it took a few hours and the garden hose at full blast to get the first pass cleaned up.

Elsewhere I saw mention of just buffing it off - with what? A floor buffer?

Hoping to get an answer quick so we can get the TWP 150 Honeytone onto the cedar before rain and/or cold weather arrives!
