I fill it with gravel and water and shake it.

I use a chain tied to a wire (kept outside the tank) to make it ease to remove.

I use Acetone and a couple of handfuls of brass 1/4x20 nuts and bolts. (brass = no sparks). Shake well, dump out residue, rinse with plenty of water. Dump out water, repair any leaks, rinse again with water. Rinse with Kerosene to get rid of water, and check for leaks. If there are any, kero will find them!

Pour in 2 packs of steel BB shot.

Mount tank in a paint shaker and shake it for about 5 minutes.

Dump out BBs ans rust/trash. Blow with compressed air.

Coat inside of tank with Kreme or other similar product made to coat the inside of fuel tanks.

When rinsing the tank, after one of the above recommended cleaning processes, dump your rinse water into a white plastic bucket. That way, you can see when the rinse water is clean of all flakes of crud. Ed

I use a pressure washer. If you do not have one a car wash would work.

Just as I thought I am ready for Lee Pedersen's Tank sealer in my ACME gastank (after days of skake, rattle and roll) , I was going to use compressed air to blow out the last remains of any leftover particles and water.....
I noticed air bubbles from one of the two, about 4" cover holes on top.
Well, after closing off the drain and filler neck and continuing with compressed air, guess what came flying through my garage?
At least I have now a fairly good size access to scrape out plenty of sludge, maybe I hire the neighbor kind (smaller hands ). But seriously, how are these manholes sealed backup? Just a press fit?
BTW, the tanks weight is approx. 125lbs (3gal), quite heavy.
Attached are some pictures, the last one shows the inside, which looks like pictures I took while spelunking in the Mammoth Caves in Kentucky.

white vinegar will remove the rust and is non toxic. Its a little slower than muratic acid but it won't rust back immediately like muratic will. On tanks that had water in the bottom and rusted only the bottom, I have often left them alone after cleaning. On tanks that were badly rusted all over, After cleaning, I treat them with "U.S.Tank" [or U.S.A. Tank] from the POR-15 people. Makes the inside look freshly galvanized and is permanant.

If you want to get fancy, I rigged up an electroytic device, putting a railroad tie into the tank as the positive electrode, (suspended so as not to contact the tank), with the tank filled with water and baking soda, battery charger negative connected to tank.

This will convert all the adhered rust back to metal, and push the stuck goo away from the metal.

I had a tank where the forty-year-old gas had turned to paste and this eventually freed it all up so I was left with bare metal.

I think its something like 5 tablespoons in five gallons, so it doesn't take much, and more isn't better. I got the recipe off the internet from a site that uses it to derust cast iron pans.

Several way have been mentioned and probably all work.

I have always used a hand full of staples, fence staples frome the hardware store--they cut better than rock, chain or bb's. Staples, a little liquid detergent, water, and shake well. Dump the water and staples and rinse several times. Drain all the water possible and then pour in a couple bottles of alcohol--rubbing kind from Wally World. Alcohol will get the last of the water in tank. Dry tank in sun and you are ready for sealer. I have had great results with product called Red Coat from local auto supply.

Good luck

The product is called Red-Kote. I have used it too. I bought a quart can to use on some small pony motor tanks. I like the fact that you can put too much in, splash it around for complete coverage then and pour excess back into the can for use on other tanks. It is a single component coating so no mixing, just clean tank properly and dry completely before treating it.
