Re: effective environmentally friendly cleaners for beach areas?



Hi Shannon:

I am assuming that the dock surface is above the waterline. If so, the likely safest thing to use on the Dock is dilute Hydrogen Peroxide (3%). When exposed to organic matter and sunlight and bacterial action it breaks down to water and oxygen. I would apply it liberally to teh "messy dock surface", let it sit until the bubbles stop and then hose it off.

Alicia Carlson from the NH Beach Program has a question:

I had a request this summer from a beach manager who has a duck and
gull problem at his beach.  In past years, a floating dock at the
beach
attracted waterfowl and, as you can imagine, they made a mess of it.
The beach users are very fond of this dock and most were quite unhappy
when the beach manager decided to remove the dock for this summer.  He
felt there was little he could do to clean off the bird droppings
without contaminating the beach water with bacteria.

Does anyone know of any cleaners that could be used on a structure in
the water that will effectively remove most or all traces of bacteria
without contaminating the water with bacteria or chemical pollutants?
Any information you have would be appreciated!

Thank you,
Alicia Carlson
