Removing grade stamps on decking

[Deep_Sinker]

Anyone have any good ideas for removing the grade stamping on pressure treated wood. I have already laid the boards down and used the best sides up and now have a few black grade stamps. I thought about sanding but am wondering if there is a better alternative? I'm a little concerned that sanding will be just as noticeable.

Wow! I've never seen pressure treated stamped,It normally has a tag stapled on the end.Where did you get it?What brand? Did you get the 40, or 60 underground rated?Also to prevent cupping the grain should be cuped ^ up rather than best looking up.Too late now.
