Gas tank cleaning

john cervini /

I need to clean a magnum tank. It has a little rust but the bigger issue is black hard dried old gas/oil. I remember hearing something about pinesol but wanted some other options. Thanks!

One or 2 handfuls of 1/2" or 1" drywall screws, shaken not stirred. Pour a few ounces of mineral spirits in there while you're shaking. Rinse, then use some evaporust, rinse again, and fill with premix.

Ice cubes melt. Screws, bolts, nuts and the like do not (edited)

None of that is needed , unless there's more rust than metal .

obviously you remove them when your'e done? i've done this to a dozen tanks, really not hard shaking 99% of them out and using a magnet for the last few.

Re: Gas tank cleaning

Use an old piece of bike chain instead of loose nuts and bolts. Much easier to fish out.

Re: Gas tank cleaning

Or you can go to a paint shop throw a guy $20 and he might let you put sand blasting hose down in there and it would look like inside of new moped tank after.

Re: Gas tank cleaning

I have a few old dog leash chains I toss I the tank and swish around with gas. Works realy well. Easy to just dump out after.

I ended up using Pine Sol. I used 2:1 ratio of pine Sol and water. Let it soak for 3 days. No agitation or scrubbing. Dumped and rinsed this morning then dried with a hairdryer. Amazing results. Perfectly clean with zero flash rust!

Re: Gas tank cleaning

If you have any Pine Sol left over, my mom used to use it to clean the crap stains off the inside of the toilet bowl. Worked and smelled great!

It also works good for cleaning ancient carbs . ;)

Re: Gas tank cleaning

I just use the pine cones from the tree in the front yard

Maybe a bit more of a mess , but , that might work . LOL

Re: Gas tank cleaning

I often wonder if those paint shakers at the hardware store would work if they could be set on "Low"?

I got tired of fishing them out 20 years ago at the cycle shop.

Time is money. When sediment is bad enough then it takes much longer to break up with soaking. Crushed ice will save much time soaking.

You're ahead time. Time you could be putting it back together and riding.

I'd have to go find ice at some store or make room in the freezer to make some and then have to wait for ice to form , as we don't keep any ice on hand .

So , how much time is saved ? Heck I could be riding by the time the ice got back from the store . LOL

Re: Gas tank cleaning

fwiw evaporust works pretty good and its reusable.

Re: Gas tank cleaning

No rinse after the Pine Sol? Surprised there’s no residue afterward

Re: Gas tank cleaning

Rinsed with hot water then put the hairdryer on it. I was absolutely expecting flash rust but I was pleasantly surprised when it didn't. Something I had wanted to try for a while. I think it was mostly varnish, not rust. I would think that any rust in the tank may flash back. Mine appears to have the original coating on it.

You would of already had ice from a gas station or motel in the time it took you to type out your previous response

Hmm , closest gas station is a 2 mile trip and motel would be at least twice that , so I don't think your timing schedule would work , for me , where I'm currently located .

Any ice would be half melted by the time I got back . :(

So , there again , all that travel time wasted . ;)
