The boat has two water tanks
and the other polyethylene.
Had diesel fuel
in the aluminum water
tank of a 45 year old aluminum hull
sailboat The tank is built in; the bottom is epoxied and attached to the hull
. The sides and top are not attached to the hull . The tanks
appear to have been lined with something (epoxy??)
Took about 2 gallons of oil
off by dipping and the remainder by pouring the water oil
mixture into a 5 gallon water carboy, filled it to the top and decanting the oil from the narrow opening.
Then several cycles of pressure washing
and scrubbing with stainless steel brushes
. Still a little oily smell and debris.
We'll next try a degreaser.
Suggestions on cleaning
the tank? We'll likely use the polyethylene tank for drinking water
and put filters on the aluminum tank.
There are seven 8 inch inspection ports
with rubber/neoprene gaskets that now have an oily smell. Any idea on how to get the oil from the gaskets?
