Gas tank cleaning…?

[farmer52]

FYI, there is a baffle in the tank so the marbles/nuts/stones will not clean that area.

Thanks for the advice everyone. The only thing I’m not understanding is how to use MMO after I weld and how much will I have to use?

Are you welding the broken bracket that holds the tank on? No need for mmo, remove it and repair.

I also need to clean the gas tank DarkMinion.

Lawn boy, If you do the vinegar way or weld, put some kinda oil in tank to coat it. Not a lot, just sloosh it around and drain. I use MMO for numerous tasks, so I always have some.

So I fill with vinegar, let sit a couple days.
Add hex nuts, slosh around.
Drain, wash with Dawn and warm water.
After rinsing, slosh around MMO in it.
Do my welding last because I have to drive up north to do the welding with a relative. I am still learning how to weld and I found out that my neighbor’s welder no longer works.

There's this stuff called Evap-O-Rust that's about $25-$30 for a gallon at tractor supply. It's really good stuff and works better and faster than vinegar, and won't accidentally discolor metal red from sitting too long (It'll darken metal though if it sits for over 24 hours). I just used it to do my tank. It's reusable for several uses so don't just dump it away when you're done. Run it through some cheesecloth to catch the chunks of rust and then re-bottle it.

I’ll pick some up.

sounds like your puttting a system to get the job done!!!!!

[LAWN BOY]

That’s what it’s turning into I guess, Lol.
