Just finished reboarding my deck,switching from pressure treated to Brazilian Tigerwood.
Started working on my railing sysyem which is iron,drilling and aligning,left for lunch and came back,lo and behold there are stains all over the deck.
Unfortunately it had rained during lunch and the shavings had immediately rusted,giving the hardwoods a look like they had beeen shotgun blasted.
Is there any method of removing this crap off the deck without discoloring it?
Here is an article I found that sums up different approaches I have taken in the past when what happened to you has happened to clients. Iron and other oxidizing metals in pelleted fertilizers is another way clients have stained their decks, driveways, and sidewalks.
Let me state that with any of these approaches you risk discoloring the wood some too so start with diluted solutions and definitely test on a small, inconspicuous area. A real paint or hardware store will have rust removal products but they will work the same so I offer the same cautions.
If you use any acidic or caustic product, make sure you neutralize the reaction with adequate amounts of water or the opposite reacting chemical.
If you got to the fragments fairly quickly, the rust stains may fade over a short period of time or the wood darken to blend them in.
It concerns me a bit you were using fasteners that would rust in an exterior application? You might want to switch to stainless for the rest of your installation?
