Thank you, I’ll see if I can get similar results as I just returned from autozone with a jug. :)
What I find funny is they claim it’s reuseable.
That’s until it turns black. You know for $23 a gal if I get one good use out of it I’m happy.

If your going to soak the rings once good is off try seafoam. Put enough in so you get a good puddle of it on top of piston and let it soak down. Great stuff it is

It's a bit expensive but it does last quite a while and is certainly worth it for the results. I've never had it fail as long as the tank is de-oiled. I hope you get the same results! Let us know how it turns out.

I did a tank with muriatic acid, too, but the acid will keep eating in to the metal itself so you have to watch it carefully. I’m glad to hear positive results about evaporust from trusted sources. I have been wanting to try it since I found out about it, but it is expensive and I haven’t had a chance to do any fun tractor work for a while.

There is also a Rust911 that I THINK might be the same as evaporust, but half the price. It’s not nearly so well documented or marketed as evaporust, so hard to know for sure. Has anybody tried that?

Looks like it is also works through chelation like evaporust, so it if is cheaper it's probably worth a shot.

If it was me before I started spending money on it not knowing the condition I would put a small chain or some rocks in it and slush them around for a while. The results of this will probably tell you if you have pin holes or not. From there you will have a better idea of what to do. And it will knock the high spots off. JMO

Sorry for the delay in replying, got busy since my last post. I found the Evaporust on ebay or amazon in a 5 gallon pail for about $60 and free shipping. It was not reusable as it was BLACK after the 3 days soak. I used the 5 gallons full strength for a couple of days and then diluted it with water to fully fill the tank and do the top 1/2.

I friend of mine when he cleans a tank puts a length of small chain and small nuts and bolts and some oil in the tank and drives around with the tank in the puck up a week or so.

Had one that was not as bad but close, soaked it with white vinegar for 2 or 3 days and would shake it up several times a day. Drained it out the sediment bowl hole that I had put a pipe plug in. Then I pressure washed it good through the gas cap hole and if you have any pin hole the pressure washer will fine them. I then took a round wire brush on a flexable shaft and put it on my drill and that finished off what rust was inside and washed it out again and dried it out with a heat gun. Then I put a couple of bottles of rubbing alcohol in it to absorb what moisture was left inside.

Set to prepping the tank for a evaporust soak.
After an hour repairing the power washers pull cord :roll: I removed the hood which wasn’t fun. The PO who “restored” the tractor once did a lot of off the wall problem solving putting it all back together. Some of which is pretty neat but some is a PITA. Well it’s off and I did take the suggestion of power washing the inside.
It’s better, there’s no pinholes which is great and there’s no gunk left so it worked well. The rust survived the assault though. I used a heat gun on low to dry it all out. Tomorrow I’ll pour in the evaporust. Looking forward to seeing the results.

Underwood wrote:X2 on the evaporust. I had almost exactly the same situation, inside of the tank looked just like yours and too nice a paint job on the hood to risk messing it up. I waxed the hood, bought a 5 gallon pail of evaporust and let it sit in the tank for 3 days (instructions said 6 hours). Still had to rinse the tank with water several times to get out loose stuff but no issues since. Didn't hurt the paint either.

I poured it in early this morning and sealed up the fill hole with gorilla tape. Once every hour I sloshed it around and changed it’s position to let a new area soak. It’s been about 15 hours and I opened up the filler hole to have a look.
:? Ok, I’m thinking this is going to take 3 days too. It didn’t do much. I’ll see what it looks like in the morning.

I've used evaporust, some parts cleaned up nice while other parts wasn't touch by it. Tried it in a tank and it didn't do much, ended up going back to a muriatic acid mixed with water.

That'd odd. The results are usually pretty quick. When you degreased, what did you use for soap?

Simple green and a power washer.
Simple green has been my go to de-greaser.
I didn’t put anything in to rattle around with it though so today I’ll go count out a couple dozen nuts from the garage and drop them in to knock stuff loose.
