Farmall Cub

Just bought my first cub. 1952. What is the best way, and products to use to clean gas tank? I put bolts in, rattled around and got most of the liaise stuff out. Then put in two gallons of vinegar and the bolts again. A lot came loose but still not as clean as I think it needs to be. Any suggestions appreciated.

I just cleaned 1, using vinegar. Put 4 gallons in it,let it set for 2 days then swish it around a bit.every two day for 2 weeks,came out nice.

I use muriatic acid, rinse it out good after its clean with baking soda to neutralize the acid

Also, look at the similar topics at the bottom of this page. Lots of helpful suggestions.

I'm currently cleaning my tank with a gallon jug of WD-40 Specialist Rust Remover Soak. Been in there 2 days and I'm seeing some really decent results. I hear Evaporust works too but Lowes only had the WD-40 kind. Non-toxic & non-caustic so it's really easy to deal with.

got r dun, It had been setting for about 4 years and was all dried up with a bunch of gunk. Used bolts rattled around, vacuumed out, put in 3 gal of vinegar, and bolts sloshed around for about 3 hours. drained, and still a bunch left, then put in muratic acid 1 qt per gallon of water, filled to the top. let set for 3 hours swished around and drained. Used baking soda water mix, a couple of gallons drained and sprayed with hose. Looked really good, sprayed the inside with wd-40. Put on the next day, and the cub started!
