(UPDATE)Cleaning my tank project

Postby Rick Prentice » Tue Mar 06, 2007 9:18 am

Since the weather isn't warming up to the 60's and 70's like I wished for, I decided to dig out my turn-table for welding or plasma cutting and strap the tank to that.

I looked around the stores for the various chemicals suggested and the cheapest was the Muratic acid at just over $5 gallon. I bought one gallon and dumped the whole jug in the tank, along with a couple handfuls of nuts, and a whole box of BB's.

After just a couple hours, the tank looked about 80-85% clean, I mean like new, except for some hardened stuff that I let soak overnight. I went out this morning and flipped the switch on the turn-table and will let it run for another couple hours.

If it doesn't come 100% clean after that, I'll drain and flush it with hot water, then dump my gallon of carb cleaner in and repeat the process.

I looked for MEK but could only find quart containers at $5. I haven't located any Lye yet.

Here's a couple pics of the variable speed, reversable set-up that I'm using.

Everything is sealed so there isn't any noticed fumes.

Rick Get lye at a hardware store, used for cleaning drains. Make sure all the hydrochloric acid (muratic) is rinsed out of the tank before putting sodium hydroxide (lye) in as a violent reaction will result. Ted

Lye used to be available with the cleaners etc. in the grocery stores. I haven't looked for it in a long time. It's probably considered too dangerous to sell to the public now............ :cry:
I'll look the next time the boss drags me to the store.
Perhaps Donny will let us know if WalMart carries it. :twisted:

Well, I don't think I'll need Lye afterall. The tank was really clean inside, except for some flakes hanging on here and there. I washed and rinsed the inside and dried it too(leaned it against the wood stove for a 1/2 hour). Then strapped it to the backhoe Cub for the final spinning. Some more small nuts and half a shovel of pea gravel. It's been spinning for nearly an hour and is looking real nice inside. Sure beats the $175-$200 the couple shops wanted.

Thanks for all the ideas,
Rick

After all that work, you should coat it with redlkote or some similar product. Modern fuel, Spelled ALCOHOL, attracts moisture and will rust your shiny interior in no time. Ed

It's not too dangerous, it's that it is used by people running meth labs.

Rick,

Here's a suggestion: when you rince the tank of the muriatic acid fill the tank with water and about a cup of baking soda. Rince it several times and you'll be good to go.

I have used the muriatic acid treatment, on a combine engine's gas tank, works slick. You really don't need to worry about using nuts, bolts, gravel, etc. to shake around inside to get it clean---something I was trying to avoid when I had a tank to clean---the acid will find the rust. I diluted mine, IIRC a cup of muriatic acid per gallon of tank capacity, filled the rest with water and let it set overnight. Tank was clean as a whistle.

Before the acid bath, I used lye to eat the varnish, etc. out of the bottom. I was told that the acid won't do much to that. The PO had drained the carb (thank goodness) but not the gas tank. 20 year old gas STINKS!

Good thing that didn't come off the back wheel! I sure would have been running fast!!! :lol: :lol: Great idea. I've heard that works great. Never tried it, but also have a tank to clean, so might give her a whirl. (No pun intended). :wink:

Some closeups of how you mounted it, and a narrative along with some suggestions for those of us who do not have that kind of kit accessible would be welcome.. and a nice addition to the list as well. :idea: :!: :wink: :D
