I was out on a boat today that has a dri-dek type flooring, and the owners agreed that it's a dirt magnet. Still, it has to beat the scars and rust stains from having the tanks on the sole!
Thanks, everybody, for the ideas. And rest assured that no chemicals used on this boat will directly end up in any kind of watershed.
For cleaning the Dri-Dek we tilt the boat up on it's trailer to a reasonable degree on it's front dolly jack and then rinse the interior. I will some times brush the Dri-Dek with my long handle boat brush but we do not spend a lot of time in season cleaning. I some times will lift the Dri-Dek up with my fingers to let trapped debris flsuh out. I also sometimes use a small, not very powerful electric power washer to spray the deck and flush the Dri-Dek of sand etc. I have a large industrial power washer that might punch a hole in the boat, lol, I do not use that one. We have low water pressure where we live, in many areas just a hose with nozzle should be sufficient to flush the Dri-Dek with the trailer tilted up. All the junk just runs out the large deck scuppers on my Whaler. If your boat does not have scuppers then I can see the issue, you might have to do a little hand/towel pick up of debris that collects at the stern as you flush the boat's deck.
Does that boat have scuppers? Is it self bailing, I assume it has a bilge. Neither me nor Chuck really have a bilge to worry over and both of us have drain scuppers I do believe to help rid the deck of water and debris. I can see how having stuff collect down in the bilge would be a problem. Still, I think Dri-Dek is your best option.
It took an afternoon to cut and install the Dri-Dek along with some creative thinking. The Dri-Dek people are super nice on the phone and even sent some extra pieces free. Before ordering look the catalog/website over to see what is offered and what you will need to complete the installation. Boats have plenty of curves etc so the Dri-Dek sometimes, most of the time, has to be snipped in stairstep like patterns.
