Cool Tank Cleaning!!

I installed a clean out port in my fuel tank last week, and then was faced with a lot of black goop, mold and such in the tank. Being lazy I decided empty the tank with a siphon, then added 1/2 gallon of a degreaser called B-52, then about 15 gallons of water in my 33 gallon fiberglass fuel tank. I let the mixture set for a while then took an air hose with a open end and "blew bubbles" in the mix. I noticed that after 30 minutes the soapy mixture had turned chocolate brown. I drained the tank, rinsed it with lots of hot (from the garden hose) water. Lo and behold the tank is as clean as the day the boat was built!!! I wiped the tank out with denatured alcohol to remove any traces of water and 25 years of funk were gone! I bought the B-52 degreaser at the local auto parts store. Sure turned a miserable job into not to durn bad!

You will rest a lot easier knowing that your tank is clean. Thanks for the heads up on B52.

It has to feel good to have a clean tank. You'll really did not need to use the denatured alcohol as you get some moisture just about the day after you add the fuel back. The vent will add small amounts and of course the separator will do it's job. Having access to the tank makes the job easier too.
