Buffing to get rid of fuzzies

Hello!  I used RAD cleaner/brightener on a new (aged 13 months) deck using scrub brush.  All gray removed and most black (minor left). But now I have the white fuzzies.  I see that you do not recommend sanding before staining, but also recommend buffing to get rid of fuzzies.  So do I just use a floor buffer with buffer pad?  But you also mention a sanding pad.  Difference there?  I want to ensure good stain absorption (DEFY extreme semi-transparent). Will it removing fuzzies reduce some absorption?  What exact pad should I use and with what wait time before staining.
