Do they use a special chemical to clean the tanks? If so what is it?
Do they have special equipment?
Just wondering. My boat sat for a few years and the first thing I did was remove the sending unit. Siphon out all the gas and try to clean it. In the bottom was some of this dark gooey stuff. I got most of it out and haven’t had a problem. Change my ws fuel filter pretty often. Tried a bunch of different solvents and none would break down this stuff.

You pretty much got it. Mechanical removal of the crud is the only way to do it right.

have you tried gas?
if gas doesn’t work, I wouldn’t worry too much about it…

Make sure when you siphon the gas out that the end of the hose isn’t hitting a baffle in the tank thus preventing you from removing all the old gas and crud. After you get all of it out you can add 5 or so gallons of gas and try to shake the trailor to suspend any remaining crud in the gas and siphon it back out. Helps a lot as well to tilt the trailor to get everything to one corner of the tank. I’ve been using a pump setup with filters on it to clean out fuel tanks with on boats that works great. Sometimes can salvage most of the fuel but unless it’s a lot of fucl it’s not worth it.
