Bottom Pait Stains and Particals

[SeaDancer]

Recently the owner of the boat next to me decided to hire someone to sand off his bottom paint. He did not drape tarps around his boat to catch the dust. As a result I have blue particals and dust on my decks and in my cockpit. I had my boat covered from the mast aft for winter. My forward deck and coach roof is a mess of of filth, stains and bloches from the dust particals.
What could I use to clean this mess up and get the white of the coach roof and grey decks back to thier original colors?

I would think that the best tool for this job would be the "hands of the offending boat owner" .....

You should also equip yourself with an umbrella drink or two while you supervise the remediation project....

Boat Zoap and bleach. If you have gelcoat porosity, this can be permanent staining and a big deal. Don't let it sit after a dew fall, clean it immediately. If it gets damp and then sits there it will stain. There are generally rules about this stuff. I'd visibly photo document it, and then ask nicely for it to be taken care of. If not dealt with responsibly, I'd go to yard management and let them know you will be contacting the EPA to mention the highly illegal bottom paint dust all over your boat. It will be dealt with right away, but you may not be welcome there again. Sounds like it would be no loss.
