You're not alone. Two weeks ago we had a similar complaint, though it was not determined if it was a hand scraped product because the original poster did not respond. I assumed it was hand scraped because it was made by Anderson whose product lines are predominately hand scraped or distressed...but after reading more into the original post maybe it wasn't?
post49631.html?hilit=dust%20hand%20scraped#p49631Yours looks pretty clean considering. Check out the responses particularly by Kevin at the page bottom.
I'm sure we'll see more complaints in the future with remodels and these types of floors. Unfortunately there doesn't seem to be any answers in how to fix except live with it or replace. Maybe we can think of it this way; it's now a distressed floor with a greyish white accent color. Grey is popular today.
