The finishing touches on the gas tank

After I used the dry gas and other alcohol based solutions (CLR, The works), there were still calcium buildups and other skitah (as my dad calls it) stuck to the inside of the tank. After reading about other peoples similar problems on the internet, I decided to try using a power washer. Ours was still winterized so I threw the tank into my truck and set off toward the car wash, I came prepared with $5.00 in quarters. First I used a soap cycle and then high pressure water. I was amazed at how much solid waste came out of the hole at the bottom of the tank (I removed the valve so the debris could be removed). Five dollars later, I now have a clean gas tank.
