A couple gallons of diesel on top of a little water and that will foul the entire bilge, or the marina!
Water, oil, fuel, coolant, and miscellaneous dirt and junk will eventually accumulate in the bilge of even the most well cared for boat. The water, whether salt or fresh, also becomes very corrosive over time. If the bilge is not cleaned periodically it won't be long before the limber holes are clogged, the bilge pumps, fouled, or worse yet, an oily slick pumped out and surrounding the boat and then a call from the marina manager.

We pump and vacuum out the oily water, steam clean/pressure wash, as well as degrease and deodorize the area. We can also degrease the engines and gears and touch up paint where needed.
