Spencer......What a shame! Don't know why that happened? Is this a cleaner of some kind? Being a new deck - it shouldn't need cleaned?
I would call Thompson's - 911 - see what they say first. You don't want to do anything to make it worse.
I personally don't like Thompson's products - long on marketing and hype - short on product performance.
CWF - by Flood Corp - is great on XT redwood - once you get this fixed - I'd go with CWF.
