Gas Tank Cleaning


Recommended Posts

Experimented with a rusty, gunked up Studebaker gas tank. Added a full gallon of white vinegar to empty tank, let it sit for four days swishing it around every so often. Drained it and washed it out well with the garden hose. Result: super clean tank down to clean metal in most places.  Total cost: about $1.59.   I'll let it dry in the sun for a few days and then I will add gas tank sealer.  I honestly didn't think it would work but it did.

You have to be careful with not covering steel entirely with vinegar.  The interface at the top of the liquid level is very corrosive.  I filled a 5 gallon bucket with 3 gallons of vinegar.  I installed my engine side cover plate in the vinegar with the level just over half way up the plate.  The intention was to let just over half of one side soak and derust, and then flip it over and do the other side.  It removed all the rust, but it also ate a line into the metal at the interface of the air and the vinegar.  You can see the line thru the Letter B and a shallower line thru the K.  My suggestion is to stay liquid full in the gas tank.     Hugh

I used the time proved serious home method for cleaning heavy rusted and heavy varnished up fuel tanks with good old fashion 100% lye ..it melts the solidified goo and embeded varnish and eats the rust and doesn't attack sound stell/iron  metal to any degree .2 pounds of it in chrystal form added to water in plastic buckets(12 gallons)  ,then fill the tank . you may or maynot rotate a few times incase of air pockets and helping hands. 24 hours later the tank is clean. Use normal care and protections.Rinse with whatever 

as required depending sealing or not.

 

Pre hot soapy wash outs pryer to any acid cleaning is usually done for loose surface crap removal.

Well, I thought I’ve linked to specific posts within a thread before but I either can’t remember how I did it or or imagined that I did it, but if you go to this thread here and scroll down to the part where he was cleaning the gas tank you’ll see my favorite gas tank cleaning method EVER.

I saw the video he referred to and it really was funny. Funniest thing I’ve seen in years and I really can’t explain to you why....

Oh yes, I forgot to mention the gas tank post is from Feb 17th - located on the 1st page of the thread about 1/2 way down.

 

And that video really was funny. I can’t exactly explain why but there’s just something about his buddy sitting solemnly on that tractor like this was a very serious piece of business and that stupid gas tank was just going around and around and around....

You could tell whoever was taking the video was trying hard not to laugh out loud.

I almost died.

For a long while Crystal lye was tough to fine like a lot of stuff chemical wise because big daddy is protecting us idiots and making life more difficult in the end..

Like offering us "green "products that barely work ,cost more and one  usually ends up using 2 or 3 times amount needed over the proper base product they replaced before you give up .

But we are safer they say. 

 

I fined the lye  easily at Walmart and Home Depot.About 4.99 for one pound container.
