Saving Gas Tank

Trying to save the original tank. Is in good condition after 70 years, but full of gummed oil or I don't know what that mass of material is called that solidified after being many years without having emptied the Gasoline.

I have saved a few tanks like that (without cutting them open). Put acetone into them, let them sit for a day, and pour it out. Methyl ethyl ketone is also good, but the fumes aren't so good for you. You may have to repeat a time or two, but in the end, I have had tanks that look like that come out whistle clean.

I was wondering if Methylated spirits might have any effect? No idea, but it might be easier to obtain? (for Mariano) It might also do nothing?

Thanks Rob and Lynn for the comments and advice.
A month ago I filled the tank with 5 gallons of gasoline and the content softened somewhat.
The products that Rob recommends are difficult to obtain here in Argentina, that is why I opted for a hand cleaning with a putty knives and some easy and inexpensive solvent that I can find here.
Then we will have to make some covers, riveting and soldering with tin.

If you can't get Acetone, then I am guessing meka is out of the question.

Do you not have home depot down there?

Home Depot left my country a few years ago..
This tank is the one on the left side, I still have to start cleaning the one on the right side, I think it is in a similar situation since I can put my hand through the mouth and I can find the same material at the bottom...
